Discontinued Overglaze

Mayco has discontinued their full line of Duncan overglazes as of September 3, 2024. This line includes Mother of Pearl (OG803), Bright Gold (OG801), Premium Gold (OG805), White Gold (OG802), and Essence (OA901).

We understand this will be a disappointment to many of our customers. We're disappointed, too. Inventory will be listed on our Duncan Overglazes page while it's available. We are actively pursuing alternative products.

As of September 13, the Mother of Pearl (OG803) is sold out. For those looking for an alternative, we recommend Sara Lusters Opal or Mother of Pearl (the Opal produces a stronger effect). These two products are still being manufactured, though there may be longer lead times than OG803 as the industry adjusts to these changes.

Mayco Official Statement

Due to circumstances beyond our control, we are announcing the discontinuation of our overglazes. 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.
