I have a problem with crushed glass when I first start blasting a lot of media comes out then it tapers down to a small amount. Then I adjust the pot allowing more media to come out, but I get that first big blast of media then the rate lowers down to get the correct rate I turn the adjustment several times open to get the media to come out enough after that first blast. When I do that that the first second or 2 its really big blast of media. I'm not sure if that's normal or is it this pot. The manufacture soda blasting systems in Houston said it is a multimedia pot. I'm blasting at 80psi. I thought it may have been I was trying low pressure like 50 but it does it at 80 as well. I blasted some max strip and it didn't do that seems to happen with the glass. I haven't had time to call them yet I will tomorrow.
