Here's my shop bench covered with a test tube rainbow! The Enamelling Course is in October, so I plan to do as many testers as I can.... That way I can take some colours with me that I know work on my PMC/Art Clay silver and get the most possible out of Lindas Course!
I got all the colours from the very friendly helpful folks at Vitrum Signum. Another incredibly wonderful person has been Joy Funnell. Joy is a Senior Art Clay Instructor and a Craftsman of the Guild of Enamellers. As my enamel choices have been a bit "hit, miss and maybe" Joy was kind enough to recommended some brands and key colours to try with fine silver.
Over the next few weeks I'll be gradually creating fine silver testers and posting the resulting trials, tribulations and colours on my PMC tips blog.
