Silicon used in hot primes

Hi, While looking up “hot” primes I have seen some compositions which contain Silicon. When I looked up on the internet I found silicon being described as a metal, is it the same thing which is used ? Regards

You want elemental silicon, not silicon dioxide (sand). A lot of people play a little fast and loose with the descriptions when selling it. It is available from Skylighter Silicon Powder, 325 Mesh — Skylighter, Inc. and Fireworks Cookbook Silicon Metal Powder -200 mesh - Fireworks Cookbook
