Smalt only, or smalt AND cobalt blue?
From the recipe supplied, it's clear this factory produced smelted cobalt glass (smalt) which contains no alumina or aluminum. But did it also produce cobalt blue which is made with smelted alumia as the matrix? I have changed the article to the company doing both, since I know it produced smalt, and it would have been a huge miss if it didn't also produce cobalt blue (from alumina) if it already had the ore, and had smelting facilities which were necessary to make smalt/cobalt glass. But I need confirmation. S B Harris 21:19, 14 October 2010 (UTC)
