I've always wanted to use that type of flux! But since I have classes with 24-30 students, I have to buy larger quantities from Rio. What ratio do you you use of the boric and alcohol?
@@LadyBerz You can get boric acid powder at most hardware stores branded as 'roach poison'. It is very inexpensive. I just use a fully saturated solution of alcohol/boric acid. Usually 3:1or so. Dip your item in the solution and burn off the alcohol and it is ready to go for soldering or annealing. 😀
A mixture of powdered boric acid and denatured alcohol works great as well. 😃
