I know that the dusting-on process is often used for this, but that is
about the extent of my knowledge. I've been curious about what other
methods if any are used.

Well, ash would be the inorganic impurities that won't carbonize and burn
away (usually silicates or other intermetallics). If your oven is hot
enough to vaporize and remove the ash, it will probably also vaporize your
pigments too. After all, they would be made of similar materials. Also,
carbon as a pigment would certainly not be an option <grin>.

You can get gelatin specified with low ash content. I just don't know how
low is low enough, and if a little ash would cause problems with your
image or not.

If/When you try this I hope you will report your findings back to us. I'd
certainly like to hear what you discover!
