I'm making a face for a wrist watch I'm building, and I want to do something in terms of a pearl coating on the dial. However, I don't have the means to melt a pearl, that would require some 6800 degrees celsius. From my understanding, calcium carbonate reacts to different chemicals in different ways, for instance it will become soluble in vinegar. What chemical could I use to make the pearl soluble while maintaining its glossy look?
The idea is to either paint or spray the solution onto the face layer by layer over a period of 1-2 weeks. Hopefully the vinegar would evaporate in this time leaving the calcium carbonate.
