A word of caution, I never knew that their was a differance in kinds of solder. I have been using winter solder and just thought it was me not knowing how to solder correctly. It has been so hot here that it took over an hour for the solder to harden up. The guy at the hardware store said that because it hardly ever gets this hot near Lake Micigan that they only special order summer solder. The other problem I had was figuring out how many ice cubes to put on my dutch oven to keep the temp where I wanted it.
