Duncan Overglazes ~ Precious Metals and Lusters

Each precious metal or luster should have its own brush! Mark each gold brush and Mother of Pearl brush to avoid contamination by other paints.

Apply to surfaces that are free of dust, skin oils and lotions to ensure proper adhesion. Wipe the surface with rubbing alcohol prior to applying the overglaze (except when using over crackle glazes). Use only in properly ventilated areas. Noxious fumes can be offensive. Be sure underlying glaze is overglaze compatible. When using precious metals and lusters on the same piece, apply and fire the metallics first.
Clean brushes with Essence.


OA901	Essence Cleaner for brushes which are used with overglazes. 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.	1/2 oz. - $6.00

Overglaze Tips & Techniques

These products are extremely prone to contamination. Even sneezing near the open bottle will allow water to become encapsulated in the product and affect the fired outcome.
1. Work in a well ventilated area, not windy or dusty.
2. Because metals always settle, turn bottle over and allow metals to fall, to mix the product to an even suspension. Do not shake vigorously. This can cause tiny air bubbles which may look like black spots on your fired gold.
3. Use a NEW or previously used brush dedicated to that product only. For example, keep the brush for OG 805 clearly marked and use only for OG 805.
4. Clean up with OA 901 Essence. Clean the brushes thoroughly and allow them to air dry. Each overglaze should have its own clearly marked bottle of Essence. Using the same bottle of Essence can cause cross contamination and affect the fired outcome.
5. A second coat of gold re-fired over the first one will improve the richness of the look.
6. In cold weather, when the ware is cold or damp to the touch, heat up the pieces in the oven to approximately 150 degrees and then apply the gold.
7. To apply Mother of Pearl, use a cotton tipped swab. For small areas, wrap a small amount of cotton on a toothpick and apply in the same manner, using a swirl or circular motion. Simply discard, no brush to clean up!

Unfired Brite Gold has a red appearance.
Unfired Premium Gold is dark amber.
Unfired White Gold is dark green.
Unfired Mother of Pearl (MOP) is light blue.

If fired hotter than recommended, MOP will have a frosted appearance. Cooler firing leaves the color shiny and iridescent. If applied over Satin glaze the MOP will be iridescent matte.
If fired hotter than recommended Gold can result in a cracked or webbed finish. With a cooler firing gold may rub off.
