i<3sgrafitto Posted April 6, 2015 Report Share Posted April 6, 2015 Hello, my studio uses a cone 10 gas kiln and I love to do sgraffito with slips on porcelain and stoneware. All of the red and purple slips that we have turn blue in the high fire. The closest we have to a warm color is a saturn orange which turns kind of a pale peach color. Do any mason stains stay red (or failing that, a warm color) in a high fire kiln? Thanks! Link to comment Share on other sites More sharing options...
Mark C. Posted April 6, 2015 Report Share Posted April 6, 2015 Red is one of the hardest colors to get in cone 10. welcome to the forum. Mark Link to comment Share on other sites More sharing options...
Chris Campbell Posted April 7, 2015 Report Share Posted April 7, 2015 Have you tried the Cerdic inclusion stains? I know of some Mason stains that stay red in oxidation, but not reduction. Link to comment Share on other sites More sharing options...
S. Dean Posted April 7, 2015 Report Share Posted April 7, 2015 I have no experience with them, but US Pigment advertises that its inclusion stains, including red, are good up to cone 10 in oxidation and reduction. http://www.uspigment.com/inclusion-stains.shtml Link to comment Share on other sites More sharing options...
Humboldt Potter Posted April 7, 2015 Report Share Posted April 7, 2015 I also do sgraffito on porcelain to ^10. For some colors I simply add a Mason stain to my clay body to make colored slip, but for red I have applied Amaco Velvet Red or Bright Red underglazes on greenware, then carved through it for sgraffito, I bisque to ^06, then glaze with a clear glaze and fire to ^10. The color stays red. The Velevet underglaze functions similarly to slip for carving. Link to comment Share on other sites More sharing options...
Betty Fount Posted April 7, 2015 Report Share Posted April 7, 2015 Inclusion Stains are the only way I know of to keep a bright red in Cone 10 Reduction. Tom Coleman uses them all the time. Link to comment Share on other sites More sharing options...
TJR Posted April 7, 2015 Report Share Posted April 7, 2015 I use them all the time, and my name is also Tom. Check out the chicken plate in my gallery. It's a Mason stain with fritt over a glaze fired to Cone 10. I have also used Degrusia Inclusion stains. They are expensive, but you get consistent results. I will look in my studio for the # of the stain. TJR. Link to comment Share on other sites More sharing options...
jamiefinedc@gmail.com Posted May 14, 2015 Report Share Posted May 14, 2015 another Q: for TJR: Which stain and how much do you add to your Mason stain? I'm doing a big group of tests, but am collecting some info first. I'm happy to let everyone know how the tests come out. Link to comment Share on other sites More sharing options...
