Thousands of years ago, the Egyptians use natrion in their mummies. It is a type of soda salt used to dry out the mummies. Traders transport the salt from hundreds of miles away. One night, the trader camp by sea shore. They build a big fire on sandy beach using natron blocks to support their cooking pots. The next morning they notice glass where the fire had been. They discovers that heating sand and soda make glass. Today globs of hot glass are rolled on giant screws to make marbles.
