Solder without using alcohol. Just dip the item to be soldered in Magic Boric and stir to coat, then solder. There will be no flaming up as there is with alcohol and no flux is needed because a flux is built-in. Works like Boric Acid Powder to prevent oxidation of silver during soldering. Magic Boric is water based, so as it evaporates, just add water. 16 oz. jar.
