You wont have to worry about going over these temps because the time it takes to disolve into solution while being heated and stirred isnt long enough to reach these temps for the most part and I use a pan with boiling water to disolve the powders while in the ba/bb and the max temp of boiling water on the stove with nothing added is like 100c which isnt close to the melting point of the powders I have you have to add oil or another substance to the water to get it to go above 100c
