Newer to the world of lampworking and looking at a few things on prometheushobby.com, and overall it looks legit, but there are a few things that are way cheaper than anywhere else. Has anyone ordered from their site before? How long did it take to get here from Turkey? Any issues with customs? Thank you in advance!

Something fun from last week, getting really happy with how the ombres are coming along consistently
Putting a little halt to my solo work has been nice, and I’m finally starting to get some prep together to share if anyone’s got some good collabin ideas, fun stuff to bring to Champs in Austin this year

I'm a scientific glassblower. It's been a very long time since I've worked with color, but I have a couple personal projects that I want to get started on and wanted some input from other lampworkers on the current state of Chinese color tubing. For context, I specifically want tubing that is machine drawn and in the standard wall/medium wall ballpark; hand-pulled tubing isn't going to be practical due to inconsistent diameter and heavy wall weight. In the past I'd shop at Mountain Glass, but sadly they seem to be out of business.

My main question is: do all the online retailers get their glass from the same factory/manufacturer, or is there a difference depending on where you shop? Any specific recommendations for suppliers?

I'm also interested in thoughts about the various colors. The palette seems to have expanded some since I last looked at it. I'm excited to see a transparent red option, has anyone worked with it? What about transparent lime? Are opaque black and white still troublesome from a compatibility perspective? Do the transparent colors mostly play nice with each other? What about the milky colors?
