2024 Product Issues

NOTE: If you have any item with the following lot #’s, please contact Mayco technical support ( ) 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.

Product Issues

NOTE: If you have any item with the following lot #’s, please contact Mayco technical support ( ) 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.

October 2, 2023: SC046 Rawhide 8oz Lot #2316036 was mislabeled. SC032 Bluebeard 8oz and Pints Lot #2322043 glaze is too thin.

  • SC-45 My Blue Heaven lot #2325041; Pint only
  • SC-75 Orange-A-Peel lot #2325043; Pint only

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.

Changes to Dinnerware Safety, CL Labels, & Clear Glaze over Fundamentals

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.

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.

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.

2023 Discontinued Items

The following items will be discontinued on January 1, 2023, or if stock is depleted earlier.’

2022 Updates

Product Issues

NOTE: If you have any item with the following lot #’s, please contact Mayco technical support ( )

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

Duncan Envisions moving to Elements & Foundations / 2023 Discontinuations

August 10, 2023
After announcing last month that the Envisions line will be discontinued on February 1, 2023, we received a number of questions about the future status of individual colors. At Mayco, we pride ourselves on being transparent and want you to be able to plan for the future. We anticipate moving over the below Duncan Envisions glazes into the Mayco Elements and Foundations lines beginning February 1, 2023. Please note the following:
  • Envision colors moving to the Foundations line will be reformulated and color matched into the Foundations chemistry.
  • Envisions colors moving into the Elements line, instead of Foundations, is either due to having a health caution seal (we want to keep the Foundations AP Non-Toxic) or because they do not work with Stroke & Coats in design due to lacing. Those formulas will remain unchanged.
Merging colors will keep the name but will have an EL or FN number. Colors not moving into either line is because of direct matches in place or low sales volume. Please keep in mind that this list is subject to change.
Duncan colors absorbed into Elements (EL) or Foundations (FN):
IN1013 (EL-152) Denim Blue
IN1015 (EL-153) Caribbean Blue
IN1017 (EL-154) Sea Mist Green
IN1019 (EL-155) Holiday Green
IN1036 (EL-156) Bluegrass
IN1037 (EL-157) Leaf Green
IN1603 (EL-158) Autumn
IN1609 (EL-159) Emerald Green
IN1640 (EL-160) Foliage Green
IN1669 (EL-161) Bottle Green
IN1653 (FN-055) Downright White

Discontinuation of Mold Production By Mayco

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 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!

Upcoming Fired Product Changes (Mayco & Duncan)

July 18, 2022

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)

Upcoming Duncan Non-Fired Product Changes

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.

Stamps & Mats Discontinued

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.

Duncan Concepts Change in Classification

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.

Stoneware Dry from 5 to 10 lbs bags

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.

2022 Price Increase

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.

Overglaze Jar & Label Change

 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.

UG-50 Jet Black (Cone 6)

 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: We apologize for the inconvenience.

2021 Updates

SW-106 Alabaster, SW-118 Sea Salt, SW-153 Indigo Rain, and SW-155 Winter Wood Slight Color Change

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.

Temporary Suspension of Certain Sizes of Products

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:

  • 2oz bottles of Stroke & Coat, Speckled Stroke & Coat, and Concepts
  • 4oz jars of Foundations and Envisions
  • 4oz jars of Clear Glaze Brushing (S2101, C300, NT-BR, IN1001, PB001, SN351)

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.

No Longer Manufacturing and Selling Slip

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.
