Can someone please inform me on the various sizes of glass tubing used in glass blowing? For example I know there is 50mm and 38mm... I'd like to know because I am designing a custom tube to order and I need to take all these things into consideration. Thank You!
8,12,16,18,25,32,38,45,50,60,65,70,75... There are some more. Checkout euglass.com or ustglass.com for sizing
