I have 3 differenet types of malachite. Malachite base, malachite
oxalate and the regular malachite that I always use for making stain.
Can I use the other two forms for making stain and, if so, can I have
the directions please. These came to my department from an old med tech
lab at our college and I whould like to use them if it's possible.
Thanks in advance.
