It has been awhile since I've had the time to hit the local thrift stores, and so in a much needed moment of thrifting, I headed out the door last week in search of good find. The funny thing about me is that I tend to thrift for similar items. My collection of ice cream makers, yogurt makers, and pasta makers could make a person laugh. Okay, it's not that bad but it's pretty close. My latest craze is pots and pans. I actually was in need of a set last fall and found a great copper bottom set for $12 at a yard sale. But I was struggling with sizing issues. When I found these beauties I couldn't resist. All told $22 for the set. I little higher that I usually spend. Taking one look at them and I knew I had hit the jackpot. The sizing is perfect for my needs, and with handles like those I can go from stove top to oven. Yeah! (My ceramic stove top was not fairing to well with my cast iron pans). When I brought them home, my first thought was that they just don't make them like they used to. But I have a question to pose. I don't really have a good background in what things were made from. These look almost tarnished on the inside like silverware. Can anyone tell me what these might have been made from and how to care for them?
