ALDON Innovating Science - Potassium Thiocyanate 500g Laboratory-Grade for Inorganic Synthesis and Chemistry Education

One of the uses of this chemical is in developing film. Negative film processes as a positive reversal with fine grain. Used in a few formulas. This stuff was 1/3 the cost from another supplier

Exactly what I needed for school for my day of science demonstrations.

It's potassium thyocyanate

This isn't quite as toxic as some reviews have suggested. This has an ld50 of 854 mg/kg. Which means a 100kg person would need to take a bottle and a half of this for a 50% chance of death which would be difficult to do because one of the first symptoms of potassium thiocyanate poisoning is nausea and vomiting which would reduce the dose you took substantially and quickly. People I believe are confusing this with potassium cyanide which has an LDL 50 of 5 mg/kg if this was indeed potassium cyanide it would be enough to kill many people. It is also a bit funny that this comes up as a top result if you search "suicide pill" on Amazon
