We recommend using this color in any type of flame. For a more opaque color use a slightly reducing flame and for beautiful transparent color use an oxidizing flame. This color can be used in any application without problems as well. We consider this color to be a striking color so the more you anneal it the more opaque it will turn. Please remember that if you thin out the color too much you will not be able to bring it back to a nice opaque color. Thanks for the continued support.
