Just started weighing all the chemicals ready to make my first batch of Pyrocat HD and all was going well until I opened the Pyrocatchenol container and where I was expecting powder I find varying sized yellow ochre particles from about 1mm to about 8mm in diameter and about 1mm thick.
I dropped a small one into some water and gave it a swirl and it does not seem to want to dissolve.
Do I have to grind these bits up into a powder? Is this the normal way they are supplied? from reading the COSHH shet they are not very good for you if inhaled so I would have thought that grinding them in a mortar & pestle would not be a great idea.
Thoughts, HELP?
