Ammonium chloride (alias "sal ammoniac")
Anyone know where to find ammonium chloride, otherwise known as sal
ammoniac, in granular/powder form? (Somewhere in the
Seattle-Portland corridor would be great!) I know welding supply
places can get the stuff in one pound bars but I was hoping to find a
small tub of it in technical grade. Found one place on the Web but
the shipping costs more than the material.
(McCreight suggests it as a flux for niello.)
Cheers!
Neil
