I have been collecting and using ci for about 6 months now and love cooking with it. I have made some good buys, #4 griswold for $5 and a#10 wagner ware for $10, but also some bad buys, ie Korean and Taiwan. I have learned a lot reading the info on the forum, has made me much better informed on what's good and what's not so good. I am in the process of building a electrolosys set up. Any tips would be great. Thank you in advance
