      Moderators needed!   12/08/2017

      Ceramic Arts Network is looking for two new forum moderators for the Clay and Glaze Chemistry and Equipment Use and Repair sections of the Ceramic Arts Network Community Forum. We are looking for somebody who is an active participant (i.e. somebody who participates on a daily basis, or near daily) on the forum. Moderators must be willing to monitor the forum on a daily basis to remove spam, make sure members are adhering to the Forum Terms of Use, and make sure posts are in the appropriate categories. In addition to moderating their primary sections, Moderators must work as a team with other moderators to monitor the areas of the forum that do not have dedicated moderators (Educational Approaches and Resources, Aesthetic Approaches and Philosophy, etc.). Moderators must have a solid understanding of the area of the forum they are going to moderate (i.e. the Clay and Glaze Chemistry moderator must be somebody who mixes, tests, and has a decent understanding of materials). Moderators must be diplomatic communicators, be receptive to others’ ideas, and be able to see things from multiple perspectives. This is a volunteer position that comes with an honorary annual ICAN Gold membership. If you are interested, please send an email outlining your experience and qualifications to jharnetty@ceramics.org.

Food Coloring - dying glazes for better application.

Recommended Posts

What type of food coloring and what color do people use? I need to dye a white glaze I use as the other glazes are also white, so it is tricky to tell how good the application is when I spray. I had read somewhere on here that people use food coloring, but no one said what brand or what colors work best without interfering with the glaze.

Is this just a test and see what happens thing or is there not a common Walmart brand and color I can just go pickup?

I've used lots of different brands, blues, reds, greens and neons in purple, aqua and orange and have never had a problem with it not burning out completely. I've also used Crayola liquid paint for kids  (blue) and it works like a flocculant plus colouring and also burned out cleanly.

The only issue I experienced, was that I added some red food coloring to my clear glaze.  It applied fine, and the color obviously burned out.  However, the food coloring, in the glaze, stained my glaze brushes a bit.  It didn't affect the brushes performance afterwards, just the look.  

I usually just get a clear that is colored pink, but accidentally bought a type that didn't have the pink.  The students kept mixing it up with other glazes, so I added the food coloring.  Apparently, whatever the company uses to dye their's isn't as strong as standard food coloring...

I sometimes use food coloring in my glazes - because I'm colorblind and many raw glazes look identical to me.   Doesn't matter which brand you use, they will all make color and burn out in the firing, i've been using McCormack from grocery store.

 

I first started doing it when I was spraying glaze - I'd put a drop or two into my sprayer pot, spray it on and change the color enough to see each layer.

Another "trick" with food coloring is for brushwork.  I use red food coloring like "ink" to do a "layout drawing" on a piece before going with a ceramic pigment.  red always burns out.   (I had a blue that left traces once.)

best,
