The son of a fire keeper .....clay, pottery, money, magnets, lens I experimented with fire and even burned stone. I found that some rocks could be hammered to shape when red hot. One particular rock I heated red hot and hammered flat started to attract red sand dust like it was wet with water.
I found that melted sand turns into a transparent rock that is very sharp and beautiful. I was able to polish a small piece into a pebble that focused bright sunlight into such a small spot that it would burn dried grass and start a fire. When I showed this to my father, he decided that instead of making clay pots to carry fire to his customers he would instead just carry the transparent pebble I made, and use them to start the fires at his customers.
