Ah...so you put it in the cheesecloth *before* dissolving it...smart!
Thanks also for the link :)

I allways fold the lumps in a peace of cheesecloth, bind it together and hang it in the water in a jar. Time does the rest. Squeeze it after 24 hours (or more). The gritty stuf stays in the cloth!

The pre-mixed is so expensive to ship, and I couldn't find the powdered stuff online, so I ordered lump gum which I've never used. I can't find any instructions for mixing it, but finally just put some in a plastic container with roughly an equal amount of water. A day later and some of the lumps have melted, but the bigger ones are still there and it's kind of gritty and hairy looking. I suppose I'll just filter out the lumps and gritty stuff - but was I supposed to do anything differently such as heat the water?
