I'll have to mix my own since I bought palladium chloride from Artcraft. For the sodium chloride I see table salt has other additives, even the non-iodized salts. Will that be OK? I also saw small bags of salt at the grocery store and the ingredient is only sodium chloride - it is in small chunk form and I was wondering if that would be a better pick than the table salt and is it pure enough? I think those bags are intended for ice melting. I would just have to grind that to powder form.
