Dear Pete.
when I melted this, I found the sodium tripolyphosphate at a place called the chemistry store online in 50 lb. bags, at about $2.00 a pound. They sell home soapmaking stuff.

I made star murrinis with cobalt blue from regular SP87, no splitting occurred.

I only tried it one time, and the crap floating on the top was a real issue for me. I hope to re visit this again because the fire opal possibilities really excite me.

Incidentally, the bag of sodium tripolyphosphte says "for use in water purification systems" , a plus!
