Duncan Concepts Underglaze

Duncan Concepts is a prominent brand in the ceramic arts industry, specifically known for its underglazes designed for bisque firing. The brand originated in the United States, founded by Erma Duncan, a pioneer in the ceramics field who established Duncan Ceramics in Fresno, California, in the 1940s.

Over the decades, Duncan became a household name for hobbyists and professional ceramicists alike. The manufacturing process is traditionally centered in the United States to ensure quality control over the chemical formulations of the glazes. The product shown, CN173 Dark Kelp, is a common example of their color-consistent underglaze line.

In terms of ownership, the brand has undergone significant changes in recent years. In 2020, Mayco Colors, another major player in the ceramics industry, acquired the Duncan ceramics brand. Mayco Colors is a family-owned company headquartered in Hilliard, Ohio, USA. Since the acquisition, Mayco has integrated the Duncan product lines into their production facilities, maintaining the brand's legacy while centralizing the manufacturing of major glaze and underglaze products within their Ohio operations.
