Hi all,
Today I did some burning/melting tests. I melted glass till it boiled, I welded the glass to a stone and much more. But you can not melt every stone, because if the stone has pores, the gases in these pores expand so fast in the heat, that the stone explodes. I also made a piece of clay to explode. This was very much fun
Here are some pictures.





The melting area in reality is so bright, that you can not watch it directly without black glasses - almost like sun
