How to Flatten Glass Bottles

Flattened glass bottles can be an interesting piece of artwork, a thematic drinks tray, or a fancy cutting board. It is not possible to “slump” bottles with normal household appliances, but once you have a kiln the process is easy to learn and fun to experiment with. Remember, if you have an accident with glass, be sure to call the emergency services straight away.
