I have a suggestion about technique. My BTH is hard, dry, and not malleable (it will break before it bends unless it's warm). Because of this dissolving it in water for IV use is the #1 frustration people have. Fortunately it's really easy if you now how. You just wrap it in 3 layers of sandwich bags, put it in the freezer for 5 minutes (which makes it even more brittle), put it on the counter and hit it with a hammer (or crush it in a vice). My BTH product will turn in to a dust.  Once it's a dust it dissolves instantly. Also, for the kind words Finally! I do not recognize your name so you must have a different SR handle than here but something about your comment makes me think you may not have tried Type-G yet. Message me on sr and we'll yap, you will be very impressed.
