Ha! says you. I know you gotta strike while the iron is hot. In this case it's really hot and malleable (that means easily shaped and hammered). Saves on electricity and energy costs this does.

It is not iron. It quickly forms a crust and it forms fissures as it SLOWLY cools. The main ingredient is silica.
