Hi I was so surprized to have so many replys to my question about the Fireless Cooker. My best hope was to get one answer. I had no idea that there were so many such products. I also did not know that there were different types. I also did not know that that they were around about the turn of the century. One learns a lot of things when doing genealogy. The one that my family had was about the size a fair ly large plastic cooler that we take on picnics or camping. It was made of metal. I don't remember whether it had two wells or not. The one that best describes it is the one where one boiled some soapstone and then put one under and one over the food. When looking at the time it took for different foods, to cook, I had to rethink that part. It seems that it is slower than solar cooking. I think that what my mom did was not just brown a roast but also started cooking it before we went to church. It would be good and hot and with the help of the soapstone it would finish cooking very nicely. My dad would not allow us to leave an oven on when we were not home watching it. Some of those products looked very dangerous. It seems like hay would likely catch on fire. Thanks to everyone who took their time to help me. I had some great answers. I will try to get a thank you out to everyone tomorrow. I always thought that genealogy was a very fun way to learn history. Now I see that it isn't just history.but so much else. Velma
