Hey all, I am working on cleaning the fossil pictured and would love advice on how to remove the plaster jacket. I was instructed to jacket it with plaster and burlap, using tin foil as a barrier. I tried using scissors which barely made a dent on the plaster, then a hand saw which shook the fossil too much for my comfort, and finally I tried wetting the plaster then cutting it with a utility knife which also shook the fossil more than I liked. I know museums use cast saws, anyone have an economical recommendation? Thank you in advance!
