I have kind of an curious topic to bring up. I am wondering about the health and safety of some old drops. In the past (and likely still in some places today) Scenics have used powdered pigments which contain lead and possibly toxic chemicals. I am wondering if anyone is aware of any safety measures to carry out when handling old drops, or possibly a test that can be carried out on old drops to determine their composition. or what the proper disposal methods might be.
I am working for a theatre that has amassed a tremendous amount of very lovely, very old drops (Some of which have no dates on them), and I am nervous about unwrapping and hanging them.
