Very easy to use and inexpensive. There isn't another composition like it on the market! Simply mix the A/B two component ignition comp and place approx ~10 grams in a square ofaluminum foil, insert a length of Imitation Thermalite™, safety fuse or an electric match, twist the foil 'bag' closed and press it into the thermite as shown below. One pound will make forty five, eight gram shots - each one will ignite raw thermite! Note: if using electric matches, we recommend our Boro/Zirconium 8000™ kit. The two part A/B kits CAN be shipped by US Mail with no hazmat fees - No ATFE required to order.
