UWE, a crock pot is a slow cooker, low temps for extended periods of time. Put supper in it in the morning and it's ready to eat for supper.
Eric, I got an expensive version of a crock pot, $5 from good will.
Dave, I use a crock pot to make the hide glue I used on my newest sinew backed bow. It was my first attempt and so far so good, although I haven't strained the bow since I sinew backed it.
