Don't go simple on molten salt baths, those things can kill you. Find plans to build one from someone who has built one. First of all I know that you don't want to weld together a steel box from simple steel. You need stainless steel pipe because the salt will eat the plain steel for breakfast, lunch, and dinner. Be aware that if you introduce ANY water into the system you could be facing a volcano of molten salts.

The strong points is 1) you can hold a precise temperature for a long period of time if it's built with a PID regulator that cuts the gas off and on and 2) it prevents oxidation by blocking out atmospheric air from the blade.
