I am a glass business in ontario that has been in business for 22 years.I kiln form glass for a living but generally stay away from colour unless it is in stock at Hollander.
If I order glass, they will not take steps to get it in a timely manor. They will not stock with consistency common colours. In the past when Hollander says a colour is out of stock I have contacted the manufacture to discover it is in stock.
There most common blue colour once took over 6 months before they got it in.Even though the factory said it had lots.
