David Gamble, lowfire clay artist, Skutt kiln expert, did an article a while back. I don’t remember where – someone out there remember? Tell us! – about the various products for decorating on majolica glaze. I asked David to recap his experiences for us. He said:
When I did all my tests I found GDC’s seemed the best – Spectrum was 2nd in my use & assessment and they had lots of color – I heard Color Robbia had some but folks I know said they did not like them & I never tested them – Mayco says that their Stroke & Coats work & yes they melt on top of whites – but I found that they were not as stiff & moved/bleed at the edges – so exact lines were out of the question with them.
All your tests with velvets on white glazes are still good with me — though not sure about food surfaces – they are so soft they would have to melt completely into the surface to be dinnerware safe. Of course you already know all of this.
Before there were GDCs, I tested the AMACO Velvet Underglazes on top of majolica. The results of this are posted on my website Handouts page. Some melted very well and were usable for majolica, some were very refractory and pig-skinned (so matt they left a crinkled, stony surface on top of majolica.)
David was in touch with AMACO, and checked on the availability of GDC colors at this point. He reported:
They are out of pink in 2oz but have pints of pink left — red & turquoise are low in pints around 10 each . Seems to be lots of 2 oz jars left in all except pink colors.
So folks should get them know while they still have a great selection at AMACO’s retail store – Brickyard Pottery- Cheri is the manager you can call 317 244 5230 or Amaco’s 800 – 374 1600 and ask for Cheri at BYP .
In my studio world, pink is safe, and so is brown. I probably have enough brown for the rest of my studio lifetime. I’d probably run out of the bright yellow (mixed with turquoise 3-4:1 it’s a great Chartreuse), Light Red, Pearl Grey, and Avocado first. At one point, I did make it a project to use brown, just to see if I could. I do like certain browns – nice ochre-tan-saddle colors, and reddish, rusty browns.

Martin’s Game of Thrones series and the house of Stark motto: winter is coming.
