How do I preserve a kiln patina? Should it be sealed in some way to ensure it stays?

Answer

I’ve found that they last for a long time on sintered bronze clay. However, unfortunately, there’s no way to preserve them indefinitely without altering the appearance. You can try applying Nikolas 2105 spray lacquer or brush on a thin layer of Protectaclear, but both will add a shiny finish that will affect the way the colors appear. You might try applying one of these coatings to a test strip to see the difference with and without.
