Work is starting to slow down and I had a chance to do a bit of prep work on some sconces I am making for gifts. Specifically, I picked up some electrical coduit (essentially pipe) to use in making candle cups. The emt is coated with zinc which can be extremely toxic when heated so today I gave the coduit a soak in an acid bath (swimming pool acid). This removes the zinc from the emt to make it safe for me to work with. This weekend, I should be able to finally get back to the smithing.
I did not know that the swimming pool acid would remove the zinc. Do you have any links to that info?
ReplyDeleteI did know that the zinc was toxic.
I did not have a link per se, but got the advice from one of the smiths on www.anvilfire.com. I did find a link at http://www.chaski.com/homemachinist/posting.php?mode=quote&p=83103&sid=04e47afb29c7f1424566f9b26c18023e that mentions it.
