I have zillions of rocks/shells/fossils/pieces of bone, etc. I am not a chemist, and I do not want to get into anything unnecessarily dangerous/toxic. Also, I would love to possibly cut and polish rocks that I find fascinating. What do I need for my “starter kit”, and can you/will you please recommend sources for these items that you work with, and that you like and trust (especially a source with great patience to answer the tons of questions I will have).
Thank you-
Karen
