Customer Testimonials

Robin Lehman Robin Lehman Glass

"The R&R GLASS-CAST 101 BANDUST investment has treated me very well. It's much easier to use because there's virtually no dust! Also the end result gets me a smoother and shinier finish. Lastly the mixture with water is very forgiving and too much or too little seems to work very well. I thoroughly recommend this product!"

"Of course I’m still casting glass with R&R® Glass-Cast™ 910 investment, and having wonderful results! The latest pieces have fragile areas with crisp lines and sharp edges. As always, R&R GLASS-CAST 910 investment worked perfectly for me. I've been telling all my students and glass friends about your products.”
