Duncan Concepts - Change in Classification (3/01/22)

March 1, 2022: Since their introduction, Duncan has always called their Concepts brand an underglaze, which 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 recently updated 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. Concepts are similar to Mayco’s Stroke & Coat glazes, which do not require a clear, unless 3 flowing coats were not applied.

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.

SP-270 Speckled Pink-A-Dot is next in line and is expected to be available to order by the end of January. Contact your nearest Mayco distributor to order. 

Overglaze Jar Change

 January 11, 2022: 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 are moving to a new size jar temporarily (see picture below for size comparison) although the contents will remain at 2gr. This will only affect the overglazes sold in 2gr units: OG801 Bright Gold, OG802 White Gold, and OG805 Premium Gold. Please note, that 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

Xiem Tools Studio X-Bevel Clay Cutter

 December 14, 2021: Xiem Tools Studio X-Bevel Clay Cutter (X10108) is unavailable for the foreseeable future.

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.

Temporary Suspension of Certain Molds

September 20, 2021: We are temporarily reducing the number of molds available to order. Focusing on the bestselling, newer, and seasonal molds will allow us to turn molds orders faster by operating more efficiently. Click here to view the list of available/unavailable molds. We will reevaluate the manufacturing suspension of the glaze sizes and molds in the first quarter of 2022. Our hope is that things will be back to normal by then and we can resume production for all SKUs.

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.
