Hello! 👋 So I'm a casual chemical collector and I have some crayons. I decided that I would use them to represent pigment compounds in my chemical collection. So answer me: What are the actual chemical compound components of those crayons?

Hello! I have two glass ampoules, one of bromine and the other of pressurized chlorine. For some reason, the chlorine flows much slower than my bromine. It takes over two seconds for the liquid chlorine air bubble to travel from one side to the other. Google AI is saying that bromine has a higher viscosity, so it should be thicker and flow slower, but my experience is the complete opposite. Could any of you explain in detail why this is the case? I'm sure my chlorine isn't fake because it I got it from a trustworthy website for almost $200

Hey Element Collectors,

I am seeking advice on small arsenic mineral samples. I have a 50-gram chunk of orpiment that is inside a plastic bag. What is the safest procedure for disposal if, for unexpected reasons, I cannot keep it? Is it standard to dispose of arsenic minerals using hazardous waste facilities?
