There are a few images of my own and other artists to show what I am talking about. If you want to see more, please check out my Blog postings for March 19, 21, 23, 26, 28 + 30, 2012. I wrote an article titled “Working With Ceramic Substrates” for Ceramics Monthly Magazine, that was published in February 2011. It told the story of my experience in finding this incredible, more or less unknown, high-tech material and working with it as fireable surface for doing glaze paintings and drawings on. As an artist trained in painting, drawing and printmaking, as well as ceramics, I have looked for something like this material for about 50 years, but it was just not developed yet. When I found it a few years ago as a completely unrelated product for the space and computer industries, it opened up all manner of possibilities for graphic/ceramic interaction. There was great interest in the article with many follow-up questions. Unfortunately, I wasn’t informed about the questions and they were often unanswered, or, if answered, it was often done incorrectly, by people who, most likely, had never experienced using the material. This blog aims to answer those questions and clarify the situation.
RANDY BRODNAX - UNTITLED - FIRST EVER RAKU-FIRED SUBSTRATE
IMAGERY ACHIEVED WITH FERRIC CHLORIDE AND RAKU GLAZE
as PC Substrates and from selected Supply Stores under the name Blank(s). This product has undergone rigorous mandatory ASTM D4236 SAFETY TESTING for Schools and General use. It is the only advanced ceramic substrate guaranteed non-reactive. The fact that these products have been through the stringent US Federal toxicology testing ensures that they are safe for handling and multiple studio firings is really important. PC Substrates are tested as safe for school-aged children, with no chronic health warnings required. From the hundreds of substrates that are manufactured for various purposes, only ONE type of substrate has been approved for art usage, and that is PC Substrates, also sold as Blank(s). The test is mandatory per the Federal guidelines for art materials sold in the US for any application. PC Substrates are the only ones that have been tested and approved.

DECALS AND CHINA PAINTS FIRED AT CONE 018 IN OXIDATION
Some of the other advanced ceramic substrates that are manufactured for various industrial applications are not suitable as an art material either because of the color, the high cost of production, the low quantity of fallout (SECONDS) available, the small manufactured size, or that it wouldn't pass the handling or re-firing safety testing.
JAMIE KOZLOWSKI - BACKLIT CRYSTALLINE GLAZE
In order to be available for sale, these lookalike materials should have the mandatory testing certification. None of them have. Technically, their vendors have been breaking the law in selling illegally. The lookalike materials have not been tested and have been creating many problems for users. They are likely made in China and use inferior raw materials for manufacture. The sheets that I use are the only ones that are tested as non-reactive, compliant and safe! They seriously affect color and glaze development in a negative way. With tested products you know what you are working with. Untested could be just about anything with no quality control.

- WHAT IS THE DIFFERENCE BETWEEN
- PC Substrate AND KERAFLEX?
- PC Substrate can generally be fired and cooled very quickly for most applications with the exception of Crystalline-type glazes which that need slow, often staggered cooling for optimum crystal development. Crystalline glazes are fired flat, eliminating flow problems.
Fallout material (with the occasional tiny flaw, that do not impact the material for art usage) is available on a first-in -first-served basis from the Ceramic Art Cart online store ONLY under the name of PC Substrates in generic packaging. They are also available in a variety of shapes, sizes and thicknesses. Information on availability is given on the Website.
This covers some of the most asked questions. If you have more, please post a comment and I will answer there. I believe that I have researched this material for ART use more than anyone else in the world, so if you want answers, get them from the Horse’s Mouth and buy your sheets from:
The Website is full of information and includes gallery images of both PCS and Keraflex. My CM article is also downloadable from there and answers many more questions. The online store also carries a very interesting range of glazes from Germany named BOTZ. My LATEST educational DVD, "INSPIRATION AND INTERPRETATION" is also available for purchase from this source. It is about surface decoration processes that I use. Approximately half is devoted to working with substrates in both cold and warm methods. As yet, this is the only video that shows the process in action. SKUTT KILNS built me an excellent, computer-controlled, special small test kiln for my research. That model is now part of their general line and called "Glazetech". It is perfect for the job in hand and holds several substrates at the same time, making for very economical firings.
IF YOU HAVE QUESTIONS, PLEASE DON'T HESITATE TO ASK
IN ABOUT TWO WEEKS IN MID-DECEMBER.
