Can I Burn Drywall Hunker

The composition of drywall makes it difficult to burn Drywall is a mixture of gypsum and water pressed between sheets of paper While the paper itself is flammable and burning will evaporate the water it takes a very high temperature to burn gypsum As a result it is not possible to fully burn drywall outside of industrial furnac...

How to Make Sea Salt 7 Steps with Pictures

The idea with this method is to evaporate the salt without risk of scorching by using low heat However depending on the amount of salt water you have this could take multiple days with the stove on and thus will cost more in energy With your pot of seawater on the stove turn on the burner to the lowest heat setting and let it evaporate...
