[QUOTE="tim_w, post: 1842196, member: 11132"] Becuase it take way longer than we can leave it in salt to reach the temp. We need higher salt temp so that with the neck actually gets up to that 800f range. Consider the study from University of Illinois using molten lead @ 1000°F it took a piece of 70/30 brass the thickness of a case neck fully submerged 19 seconds to reach the same temp. With 3/4 of the case out acting as a heat sink and the fact we can not leave it in more than 5-8 sec or the body gets too hot we need much higher temp. Consider that propane torch flame outer tip os close to 2000°F To answer another question asked. Tempilaq can only work where its not in the salt. It can be put on the body using 400 to ensure they do not get too hit. But on the neck in the salt will not work as its measuring the temp of the salt touching it not the internal core of the brass. I hope that all makes sense. Its all counter intuitive on its face. [/QUOTE]
