[SEL] Annealing Aluminum

[Ed Herreid]

Rick.
 
To anneal the aluminum you need to heat it to a temp around 600 to 700 degrees F and let it cool.  
 
Aluminum does not change color as it heats like steel.  So it is difficult to judge temp.  If you heat it too much it melts.  
 
He is using the change of color of the soap to judge temperature.
