How To Mix CMC Gum Solution for Ceramic Glaze

[@IamAli89]

hi nice video, have a question, is the CMC powder (food grade or chemical grade)?. thanks

[@BlueNoseTrading]

Thanks for watching! I used food grade because it was what I found first. For the purpose of suspending glazes, I don't think it would much matter which grade you went with.

Good video!

Glad you enjoyed it 😊

Let's say we have a glaze that simply drips off the bisque ware during the second firing. And, it's really only this maple colored glaze. Do you think this CMC Gum stuff would help with that?

[@BlueNoseTrading]

The CMC gum isn't really going to affect how the glaze is running or behaving in the chemistry of firing. It's main purpose is to thicken for easier brush on application, and to harden the glaze when it is dried to the bisque to make it easier to work with while you are loading into the kiln. The amount that a glaze is running on a body is going to be related to the amount of flux and the glaze chemistry. I'm not a great source for glaze chemistry (yet). I recommend you check out John Britt on KZbin. He has some really awesome free courses on glaze chemistry. kzbin.info

@@BlueNoseTrading I didn't think adding a glue would do much in a 1800+ degree kiln. Thanks for the tip on the flux. I really just think it's a bad batch of glaze. ❤

How long does the solution last for?

[@BlueNoseTrading]

Thanks for watching, the general internet says "one year" for the CMC solution, but I think that is more in reference to food safety and consumption. I have glazes that have solution added that are well over a year old. The solution still works, but it can get a little stinky once the solution has "soured".

Mine got liquid in about a week time 😕.

if am to stabilize passion fruit juice can i use the CMC made solution without need to boil the passion fruit juice?

[@BlueNoseTrading]

Unfortunately I have no idea, I only use CMC Gum solution to increase brushability in ceramic glaze applications. Best luck!

bravo

Thanks for watching 😊

Mixing time?

[@BlueNoseTrading]

Probably around 15-20 minutes at least. You have to keep mixing until it's completely smooth and free of lumps.
