Due to the demand for Mayco slip cast mold shapes that exceed A Ceramic Shop’s production capacity, Mayco will transfer its mold production to Clay Magic Inc, who will distribute Mayco molds for sale alongside their shapes. The final day to place your order for Mayco Molds at A Ceramic Shop is June 1st. All outstanding Mayco mold orders will be fulfilled by August 1st.

If you would like to place an order with A Ceramic Shop, please contact Bill or Michael at aceramicshop4003@aol.com or call 614-337-9042.
Mayco expresses its gratitude to A Ceramic Shop for keeping the Mayco molds available since our in-house production ceased in 2022. A Ceramic Shop will continue to offer a variety of other mold shapes, bisque, and color products to support the industry.
About Clay Magic Inc: Located in Rockwood, Michigan, Clay Magic Inc is a well-known provider of a diverse catalog of clay molds for ceramic artists and enthusiasts alike. We are confident Mayco’s iconic mold shapes are in good hands with Clay Magic. Visit their website at: www.ClayMagicInc.com
April 11, 2025:
Tariffs:
We have received many questions from our distributors and consumers about how the new tariffs will impact our pricing. As I write this at 7 am on Friday, April 11, 2025 (I feel the need to time stamp this), President Trump has paused on the country-specific reciprocal tariff rates (ranging from 10-50%) for 90 days, leaving the earlier tariff rates in place. However, tariffs on goods from China and Hong Kong were not included in the pause and are now at 145% as China and the US engage in a trading skirmish.
For now, Mayco will be able to absorb the existing tariffs on raw materials from all countries except China. Fortunately, most of our raw materials and packaging used in the production of glazes are sourced within the US, Mexico, and Canada. Earlier this year, in anticipation of the threatened tariffs on Chinese goods, we purchased large quantities of those raw materials sourced from China and have an adequate supply for the next several months. So, barring other unanticipated costs or events, we do not expect a price adjustment on color for at least the 90-day pause and hopefully longer.
Bisque, also sourced from China, is a different situation. We are holding prices while we monitor movement in the tariffs. If the high tariffs stay in effect, then we will undoubtedly have to raise our prices. We commit to absorbing all of the increased costs we can and will work to find other cost savings to reduce the impact as much as possible.
We understand the importance of keeping the cost of doing ceramics affordable- whether as a hobby or business. We are optimistic and hopeful that this volatile situation will settle favorably for our global economy. We promise to keep everyone informed as the situation changes and new information is received. In the meantime, remember that what we do is a wonderful escape from some of the harsher realities of life. Keep making pottery, and the world will be a more beautiful, happier place. Make it Mayco.
-Colleen Carey Brennan, Mayco CEO, President
Additional paragraph for PYOP’s
It is important to note that if there is an increase in bisque pricing, it is ideal to determine the profit margin that you want to obtain when pricing your products. This differs from taking the new wholesale price and using a standard multiplier. Adding the increase to your current price allows you to maintain your profit margin.
While this is a challenging time, it is important to remain optimistic and continue to offer an engaging atmosphere for your customers. We all need some lightness in our days, and your studio is a place for people to connect and rejuvenate through art.
-Crista Toler, Mayco Market Specialist PYOP Manager

We have seen the posts and received several complaints about inconsistent and varied results when using SW219 Opal Lustre. Our lab and in-house designers have extensively tested this product and concluded that while it shows a range of variability under different application and firing conditions, it still performs to our standards. To help inform customers about the variability from this glaze, we will be sticking the top of the jars with the following statement:
NOTICE: Due to varied results, Mayco has done extensive testing of SW219. This product has a wide range of variability. Clay body, application, firing process, and temp will affect the fired results. We recommend testing cone 6 (1222°C/2232°F) in a lightly packed kiln on a white stoneware clay body with texture. If you are unable to test and accept varied results, we do not recommend this glaze. If you are unsatisfied with the results, this glaze looks great in combo with other Mayco glazes.
We appreciate everyones help in sharing their results and assisting with testing.
September 3, 2024: Due to circumstances beyond our control, we are announcing the discontinuation of our overglazes (OG801 Bright Gold, OG802 White Gold, OG803 Mother of Pearl, OG805 Premium Gold, and OA901 Essence). This decision was not made lightly and was influenced by various factors and challenges. First of all, we recently updated toxicology on the overglaze line. Due to stricter regulations recently implemented for both consumer health and the environment (including transportation), the warnings and requirements for safe use and shipment have greatly increased. Further, we have been dealing with significant packaging issues. After meeting with our supplier, it is their decision to not reformulate to a more user-friendly formula, nor are they willing to replace the antiquated equipment that is causing the packaging problems. This product line is a very small portion of their business, which they no longer wish to support. Given the myriad of issues, we have decided that discontinuing this product line is our only choice.
We recognize the disappointment this news may bring to our customers. However, alternative options such as Laguna Lusters and Colorobbia Lustres are available. Mayco continues to be deeply committed to maintaining the highest standards of quality and safety in all our products, and we apologize for the disruption this may cause. We have given all of our distributors a chance to order. Please check with your favorite distributors on their overglaze stock.
January 5, 2023. The following products will be discontinued beginning January 1, 2024.
Discontinued Sizes:
Stoneware Bisque
Earthenware Bisque
For database purposes and consistency on our website, marketing collateral, etc., we will change our item number format to remove all dashes. For example: SC-1 will be SC001, FN-001 will be FN001, CG-1000 will be CG1000, DSS-1000 will be DSS1000. This is a rolling change to everything that displays an item number, such as labels, price list, charts, literature, website, accessory inserts, silkscreens, and stoneware bisque labels.
NOTE: If you have any item with the following lot #’s, please contact Mayco technical support ( technical@maycocolors.com ) with a photo of the lot #, located above the barcode.
April 4, 2024: It has come to our attention that UG050 Black, lot #2408060 in 2 oz size only has a viscosity collapse issue and is not up to our standards. While the lot passed our quality control check when manufactured, the glaze became watery in the jar and does not get better no matter how much you shake it.
May 30, 2024: It has come to our attention that SW251 Pink Opal, lot #2411046 in pints is not performing to our standards and color.
June 1, 2024: SW219 Opal Lustre Pints from Lot# 2407077 are developing darker, with less color variation. While technically within spec, it does not meet our high standards for a new product release. We request pints from lot # 2407077 be removed from distributor shelves and consumers contact technical support if they have pints from Lot# 2407077.
June 28, 2024: SW501 White Gloss lot #2417075 has a viscosity collapse issue and is not up to our standards. While the lot passed our quality control check when manufactured, the glaze became watery in the jar and does not get better no matter how much you shake it.
You asked for it and we listened! EL-159 Emerald Green and EL-161 Bottle Green are now available in gallons! The cost is the same as the FN-219 Lustre Green. Get those Christmas trees ready!
NOTE: If you have any item with the following lot #’s, please contact Mayco technical support ( technical@maycocolors.com ) with a photo of the lot #, located above the barcode.
April 4, 2024: It has come to our attention that UG050 Black, lot #2408060 in 2 oz size only has a viscosity collapse issue and is not up to our standards. While the lot passed our quality control check when manufactured, the glaze became watery in the jar and does not get better no matter how much you shake it.
June 30, 2023: Three lots of SW-140 Black Matte that have white specks in them. The lots that were affected are #2230077, #2244094, and #2301036. The issue has been fixed and we have new product in stock.
June 15, 2023: SW-146 Aurora Green with lot #2242059 is falling out of suspension/separation and doesn’t get better no matter how much you shake it.
June 5, 2023: UM956 Silver Ultra Metallic Acrylic Paint with lot #2235104 is turning hard and chunky in the jar.
While all three lots passed our quality control checks when manufactured, we discovered that the glaze started to degrade in the bottle over time. The fired results bubble, mottle, blister, and in some cases, the pigment changes color.
November 2, 2023: CG-1004 Berry Tart 4oz and pints of lot #2326061 fading.
November 15, 2023: EL-158 Pine Needles Lot #: 2301054 in 4 oz and Pints are thickening in the jar but can be reconstituted by adding a little bit of water at a time and mixing before use. The fired results are the same.
February 9, 2023
Products Moving to a CL label: Due to ACMI’s toxicologists taking a more conservative stance on the limits allowed for soluble copper to be considered non-toxic, the below colors will be moving to a health caution label (CL) with the next round of manufacturing.
Changes in Dinnerware Safety for Elements: Below is a complete list of the Elements and Elements Chunkies that are not recommended for dinnerware due to updated surface durability testing (this testing is for cone 06 (999C/1830F)). The glazes listed are not recommended for dinnerware use. All other Elements are considered dinnerware safe, even those previously considered unsafe, as they did not react to our surface durability testing.
Changes in Clear for Fundamentals Underglazes at mid-range Cone 6: Below is a complete updated list of the Fundamentals Underglazes and Designer Liners that are recommended to use with SW-004 Zinc-Free Clear when fired to cone 6. This change is primarily due to some reformulations with chrome pigments. The liquid and fired color results remain unchanged. SW-001 Clear can be used on all other Fundamentals Underglazes and Designer Liner colors not listed at cone 6.
January 1, 2023: Due to the number of new products we are adding in 2023 and space limitations, we took a hard look at our sales and determined that some products were not meeting our production goals. One of the biggest changes is the discontinuation of 72 Stoneware Dry which does not meet our production goals. The following items will be discontinued on January 1, 2023, or if stock is depleted earlier.’
Just a reminder: Envisions will be discontinued on 2/1/2023. We are manufacturing the colors that will merge into the Mayco palette (Foundations Sheers and Elements) and will advise when available. We would suggest purchasing the Mayco version as soon as it is available.
Jungle Gems
Elements
Accessories
Stoneware Dry
Please note, the liquid pints of the following colors are still available.
Silkscreens
Earthenware Bisque
Stoneware Bisque
NOTE: If you have any item with the following lot #’s, please contact Mayco technical support ( technical@maycocolors.com )
November 3, 2022: CG-999 Jazz Notes with lot# 2217054 in 4 oz only was bottled with the wrong color crystal. The CG1000 Mardi Gras purple and blue crystals were used instead of purple, yellow and green.
October 7, 2022: SW-118 Sea Salt with lot #2222083 was bottled with the wrong color crystal. The fired crystal will look bright green instead of sage green.
November 2, 2022: AS964 Duncan No Fire Snow with lot #2201005 is becoming hard in the jar and unusable.
June 1, 2022: It has come to our attention that SW-144 Lava Rock lot #2131085 was incorrectly labeled and is firing as SW-145 Tea Dust.
March 3, 2022: It has come to our attention that lot #2201027 of SW-100 Blue Surf and SW-115 Midnight Rain pints contain incorrect pigments resulting in a lighter fired color than our standards. See photo below; left is the correct color, right is incorrect.
January 4, 2022: An incorrect pigment was used in the manufacture of Fundamental Jet Black UG050. The low fire (cone 06) results are correct and meet specifications. However, users will get undesirable results (turns brown) if used at mid-range (cone 6) with a zinc-bearing glaze. Please check your stock for lot codes #2142117 and #2144010. Again, this product is acceptable for use at low fire or if the mid-range customer uses a zinc-free clear.
November 22, 2021: 4 oz Duncan No Fire Snow was mislabeled and has a ‘kiln required’ icon and cone 06 firing instructions.
October 29, 2021: We have discovered a technical issue with two lots of SC-75 Orange-A-Peel. Please check your stock of all sizes for lot codes #2131068 and #2134068.
September 3, 2021: CG780 Mystic Jade, 4 oz only, lot #2112098 has the wrong crystal in the jar. This product itself is not defective – just not to our standard due to the wrong crystal.
May 18, 2021: SC-18 Rosey Posey lot # 2108062 is defective due to viscosity collapse and water head formation. Sizes include 16oz, 8oz, 2oz.
March 15, 2021: CG977 Ink Spots, 4 oz only, lot #2043052 has the wrong crystal in the jar. The product itself is not defective – just not to our standard due to the wrong crystal.
December 1, 2020: We have a defective lot of SC-70 Pink-A-Dot due to a batching error. The product will be watery and affects all sizes. Please remove lot #2037083
We have been struggling with our mold production for quite some time due to labor difficulties. This situation has become even more challenging as our plaster mixer requires service almost daily. We can no longer get parts so our maintenance department struggles to find fixes. As a result, we have made the difficult decision to discontinue mold production. Please note that this decision was not made lightly but unfortunately, we are limited in the number of challenges we can overcome.
However, we do have good news. Mayco molds will live on!! A Ceramic Shop will be purchasing all of Mayco’s Molds to produce and sell from their Columbus, Ohio facility. A Ceramic Shop is well known in this market as a manufacturer for several other mold lines: Lakeland, Kentucky Pottery, IMD, and Tag, among others. They are also the producer of Doc Holliday Paints and are very familiar with this market.
Mayco will be at the Hamilton Mold Show in September but we will not be taking preorders or selling molds. We are accepting mold orders from distributors until August 1st. However, given our limited staff and undependability of equipment, we may have to transfer business to A Ceramic Shop earlier than planned. Mayco distributors will be able to continue to purchase Mayco molds from A Ceramic Shop. However, there are direct purchasing opportunities as well. If you wish to speak with Bill or Michael from A Ceramic Shop, you can email them at aceramicshop4003@aol.com or call at 614.337.9042.
This was one of the more challenging decisions we have had to make, given our commitment to surface design and the slip casting community. While molds were never our largest revenue stream, a significant amount of time and effort has been devoted to them over the 30+ years we have been designing and manufacturing. Our design team will continue to feature Mayco molds (and others!) in our project creation. Long live Mayco Molds!

New glazes: Keep an eye out for some new glazes coming in September. They will be “EZ” peasy to work with. And, we are working on a strong low fire and stoneware color release in Spring 2023! Get your glaze brushes ready!
2 oz Stroke & Coat, Speckled Stroke & Coats and 4 oz Foundations are back in stock!
Mayco & Duncan Clear Glazes: All 4 oz clear glazes jars are discontinued. CN2000 Clear Dipping (Duncan) is discontinued in all sizes as of September 1, 2022.
Duncan Concepts: Due to diminished sales and continued production capacity limitations, Concepts will be discontinued on September 1, 2022. View our conversion chart for a list of color matches in the Stroke & Coat line.
Duncan Envisions: Due to diminishing sales and continued production capacity limitations, Envisions will be discontinued in February 2023. Many of the colors in the Envision palette have direct matches in the Mayco Foundation line. Most of the remaining Envision colors in the Best of Duncan palette will be merged into either the Mayco Foundations or Elements product line. View our conversion chart for a list of color matches in the Foundations and Elements line. (See the updated Envision news above)
July 18, 2022
Duncan Sprays: The Gloss, Satin, and Matte Sprays are discontinued as of July 11, 2022. Our Spray manufacturer has discontinued its private label program.
Duncan Bisq-Stain Acrylics: OS431 White and OS476 Black in 16oz will be discontinued on September 1, 2022. The 2oz and 8oz sizes remain available.
July 1, 2022: This year we were given a significant increase (70%) from our Mat and Stamp supplier due to the increase in raw materials, particularly rubber and resin. Unfortunately, this increase would put the price well over what we believe the market would be willing to pay. In addition to the increase, the supplier has had trouble keeping us in stock on our existing designs, causing further shortages. After much consideration, we have decided to discontinue these product lines. Please contact your nearest Mayco distributors for any leftover stock.
March 1, 2022: Since their introduction, Duncan has always called their Concepts brand an underglaze. However we disagree with this language because technically it is not due to being frit-based as opposed to clay-based. To our knowledge, Duncan promoted this brand – at least initially- with instructions to apply a clear glaze. However, with the acquisition of Duncan and distribution through Mayco distributors, new consumers are being introduced to this product, thinking it is an underglaze. This causes confusion and sometimes poor or unexpected results, such as having a gloss finish and adhering to kiln shelves. To clarify and educate new consumers, we are updating the Concept label and our website, removing any reference to the term “underglaze” and begin positioning it as a glaze. The label change will be rolling. We would ask that distributors and dealers make the same changes in your presentation on your website, shopping carts, etc by classifying Concepts as a glaze and removing any reference to underglaze.
March 1, 2022: Stoneware drys are now available as 10 lbs per pack. We believe the 10 lbs. quantities are friendlier to the consumer and recommended when dipping. The 10lbs will remain in the current bag materials for environmental and storage purposes. Any orders moving forward will be in a 10lb unit with the updated pricing as of March 1.
March 1, 2022: Effective March 1, 2022, Mayco will be implementing a modest price adjustment on color, bisque, and decorating accessories The increase is directly attributable to the increase of raw materials, packaging, transportation, and operating costs. Click here to view our product price list.
March 1, 2022: The following silkscreens are discontinued.
DSS-0137 Cutesy Animals

January 11, 2022:We recently updated the Overglazes to have a Mayco branded logo. See the picture on the right for the new label. As a reminder that in January 2021, we announced that our overglaze manufacturer is unable to obtain our normal 2gr jar due to the demand generated by the COVID Vaccinations. We are uncertain of when our normal jar will be available. We moved to a new size jar temporarily although the contents will remain at 2gr (see picture for size comparison). This will only affect the overglazes sold in 2gr units: OG801 Bright Gold, OG802 White Gold, and OG805 Premium Gold. The larger jar will appear to be short-filled but it contains the same amount as the previous bottle and as the label states.
January 11, 2022: An incorrect pigment was used in the manufacture of Fundamental Jet Black UG050. The low fire (cone 06) results are correct and meet specifications. However, users will get undesirable results (turns brown) if used at mid-range (cone 6) with a zinc-bearing glaze. Please check your stock for lot codes #2142117 and #2144010. Again, this product is fine for use at low fire or if the mid-range customer uses a zinc-free clear. However, if you wish us to replace it, we will be happy to. Contact our technical team at: technical@maycocolors.com. We apologize for the inconvenience.
November 5, 2021: Due to the discontinuation of the AmTalc 98, we have had to reformulate SW-106 Alabaster, SW-118 Sea Salt, SW153 Indigo Rain, and SW-155 Winter Wood. Users will notice a shift in the wet glazes (from grey to buff). but the fired result will essentially be the same, depending on firing temperature, atmospheric conditions of the kiln, application, and underlying clay body.
UPDATE: February 2, 2022: Despite our best efforts, the discontinuation of AmTalc 98 has slightly changed the fired result. Users will notice a slight shift in the fired color result. Please note that the fired result is dependent on firing temperature, atmospheric conditions of the kiln, application, and underlying clay body. The crystal loading has not changed. See below for the wet glaze color comparison of SW-106 Alabaster and the comparison of fired results on chips.

January 11, 2022 Update: We know that this suspension has impacted some of you more than others. We are working on a plan to re-introduce a limited palette of the top-selling colors sometime towards the end of the first quarter. We will let you know as soon as we have the manufacturing availability and list of products. Again, we apologize for this disruption but hope you understand that this suspension has allowed us to keep more products in stock as we are unable to recruit enough employees to staff all of our bottling lines.
September 20, 2021: We are temporarily suspending production of certain sizes in the following product families:
We believe it is better to be stocked in all colors of some sizes rather than some colors in all sizes. We currently have an inventory of these sizes, especially the holiday colors, and will continue to sell them until we run out.
September 20, 2021: We have made the decision to cease production and sales of our earthenware and stoneware slip indefinitely. Slip is labor-intensive to produce, requires a great deal of valuable manufacturing and storage space, and is more a regional product due to expensive freight costs. We will refer business to other suppliers such as Columbus Clay, Laguna, and Standard, in addition to local suppliers.
