A.R.T. Glazewerks Maiolica colors

Thanks to the nice people at A.R.T. Studio Clay Company, I have just tested their Glazwerks Maiolica colors on top of my standard white majolica base (listed in the Majolica and Lowfire handout here.) The tile was fired at 200 deg/hr to a cone 04 visual at about 3 o’clock (about 1950 deg F at this ramp). If you have a kiln sitter, that would be an 03 sitter cone. Right side is a double coat. The results look good – a workable substitute for the discontinued AMACO GDC colors. Yay! See the tile below. I tested 10 of the colors. The remaining test were mixes of colors. Product is listed in their catalog on page 12:

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. Below, a bowl from 2003 during the self-imposed brown challenge. Summer flowers on the front, winter leaves on the back. Perhaps the theme presaged my later immersion in George R.R. Martin’s Game of Thrones series and the house of Stark motto: winter is coming.
