What is gym chalk made of?

Things weightlifting "chalk" are NOT made of:

Blackboard chalk is calcium sulfate or calcium carbonate. Great for a teacher writing lecture notes in front of a class, terrible for helping sweaty palms.
Talc is a clay mineral composed of hydrated magnesium silicate. It's often used as a dry lubricant, exactly the opposite of what you would want to improve your grip.
Baby powder is talc mixed with corn starch. Since talc is a dry lubricant, it would actually make your grip worse than nothing at all.

When you are looking to buy chalk for gym, you should always be looking to buy 100% PURE magnesium carbonate (MgCO3)chalk. There is a wrong perception that every chalk is the same, people like to say "chalk is chalk", but that's not true, I've tried few different gym chalks, and found few good ones, but also few that are not that good quality. It also depends on your hands, how sweaty they are are when you use chalk etc., you should try and test few different chalks and see which one is best for you. Neba-sports chalk was best for me and I'm using only that one now.
