Hi all, i really hope you cold help me to find a very important answer:
i burned a little quantity of commercial silicone (the same silicone you can commonly find in shops) a obtained a quite-white powder. Someone can explain me what kind of powder is it? i would really appreciate to know by which chemical groups is it composed.
Thank you in advance, ask me if i need more details or if my request is not clear.

I could look it up, but I think I can guess.  Let's try to figure it out together:  what compounds make up silicone?  What elements are present?  Can you look up some of that on Google?  What is the nature of some of the elements?  Burning to leave a white powder, now that's something that doesn't happen all the time.  Look up: refractory, and see if its a useful hint.

Silicone is known to leave a silica powder when burning. I also did it as a teen, with the same result.
