Fire Up for Intense Blue

Recently, while testing CerPrint Blue and CerPrint Black toners, I wanted to see how high I could fire before the temperature affected the two pigments.

Using our High Fire Lamination paper, I printed and laminated one black and one blue decal sheet and applied the decals to regular 4×4 porcelain tiles. I fired to 1825 degrees Fahrenheit–or around Cone 06–using the normal firing schedule.

The black toner performed as I expected, resulting in a grayed out image. However, the blue really surprised me. The result was a beautiful, rich Chinese blue. I’ve included a picture of that tile. I knew that the blue toner could survive much higher temperatures, as I had tested up 2,000F previously using an unfluxed decal paper. At 2000 F the image was somewhat faded, but acceptable. This sheet fired at 1825F really pops.

I am not sure how using an unfluxed decal paper and firing to maybe Cone 04 or Cone 05 over a Cone 06 glaze would work. Anyone want to give it a try and tell us how it worked? Drop us a line through the contact form.
