I highly doubt that there are any carbonates present. I use it to make boric acid, the yields are quantitative, and there is no observable evolution
of carbon dioxide upon addition of HCl.

It might have some carbonate. There's also some insoluble garbage in my experience. It's pretty easy to hot filter the solution and make nice
crystals. They're quite hard so I don't recommend glass. The bottom of a milk jug makes for easy crystal recovery.

Yeah, always hot filter. The insoluble crap might be cardboard from the inside of the box it gets shipped in. I live only about 150 miles from where
it is mined, so maybe that's why I don't get much "insoluble junk".
