Overglazes by Duncan

Duncan Brand Overglazes.

We've captured the timeless, iridescent beauty of everyone’s favorite gemstone and transformed it into a translucent overglaze, ideal for adding that classic luster to your pieces!

Mother-of-Pearl can be easily applied and its appearance will vary with the type of glaze over which it is applied. Over a gloss glaze, Mother-of-Pearl adds a shiny luster and when applied over a matte glaze, it adds a subtle sheen.


Go for gold with Duncan's Precious Metals! Apply over fired glaze to add brilliant gold accents that’ll make your project look like a million bucks!

One coat of Precious Metals offers opaque coverage. Apply over gloss glazes for a shiny sheen or matte glazes for a subtle luster.

    How to use Essence
    Swish overglaze brush in solvent until bristles are free of product. Wipe on paper towel.

    Don’t let water and other solvents get the best of your projects! Capture the essence of good brush and tool hygiene with Essence – the must-have solution for cleaning all of your brushes and tools used with overglazes. 

    Essence is the perfect accessory to working with Duncan overglazes; other cleaning agents may contain water or solvents, resulting in the separation of overglaze during subsequent applications. Use a separate bottle of Essence for each overglaze product.

    Tips & Techniques

    Use a separate bottle of Essence for each overglaze product. Mark the bottles according to which overglaze product was used. Contamination can result if brushes and/or Essence used with one product come in contact with brushes and/or Essence used with another. For example, if you use Bright Gold and clean your brush in one bottle of Essence, then clean a brush used with Mother of Pearl in that same bottle of Essence, contamination will result and compromise all subsequent firings.
