Does anyone in the U.K. stock preciosa Ornela (Czech) glass?
I'm not sure but be very careful, the COE is not consistent and its not always compatible even with other glass that is meant to be the same, its also very spitty, like frit on a stick. I think I have a sample pack but I don't use it I had to many problems. Its a real pity as some of the colours are beautiful.
I've recently bought some Czech glass from a supplier in Germany and I've had no problems with spitting.
I haven't mixed it too much with other glass yet (apart from adding dots) but so far no issues. Shipping is very reasonable too, you can buy per rod or different size batches!

Thanks for the link Trudi
I have used it before Nikkei, I found the trick is to pre heat it by using a rod warmer or putting them in the kiln.
