Review on 🌈 Assorted Rainbow Iridescent Glass Sheets - PALJOLLY 9 Sheets, 4 x 6 inch Stained Glass Sheet for Mosaics and Glass Hobby Projects by Amy Mcleod

(Multiple boxes ordered including this rainbow box, 35 total) - Strange granular white almost powdery surface on 26 of 35 pieces that does NOT move regardless of cleaning tool or chemical. I've soaked it in hot, soapy water overnight, tried non-ammonia glass cleaner, standard cleaners, rubbing alcohol, hydrogen peroxide, GooGone, WD-40, and acetone. Every sponge and bristle structure imaginable has been used and no modifications have been made. Almost like leftover cement paste or something. Makes parts in stained glass completely unusable. The quality of all glasses is very low. Lumpy, with air bubbles galore,
