Holy smokes....I ran over and bought 25 lbs and it works amazingly. Yesterday I mixed one cup plastic and 1/3 cup of salt in a Pyrex and poured some ikas. The first batch weighed 9.7 grams. The last batch weighed 11.8. I can't get the salt to stay suspended while pouring. However the glass beads stayed suspended and all six batches of ikas weighed in at 10.6 grams. They r really look nice and clear too. Thanks Montees for the help
