Hi all. I am new to this forum and am working on etching. The ferric chloride has been tried a few times. While searching for better ways to etch using ferric chloride I came across an Instructables on how to etch with muriatic acid so you do not have throw out your solution when saturated with copper.

When I tried the Cupric Chloride the I made sure the area was well ventilated but I believe the cold slowed down the etching process so much that the traces also were partially destroyed.

Has anybody found a fume hood that will handle cupric chloride? Etching outside or with a window open is not a good option in the winter.
