Total base recipe 500
+ Stain 50
To 500 g batch of dry ingredients (plus stain) - add 300 g of non toxic antifreeze, mix well, add just enough water to get a pudding consistency.
Weigh 350 g of prepared mixture and add 25g snot, mix thoroughly with immersion blender, scrape sides frequently. I don't sieve underglaze for screen printing, the screen is 110 mesh or finer. While the underglaze alone is a nice consistency on its own without the snot, it will dry super fast and clog your screen, and it will chip off the paper. Maybe experiment with leaving the gum out if you are printing directly onto clay slabs? Try it and let me know.
How to make snot - to one cup of boiling hot water in blender, add 3 heaping teaspoons of CMC powder, blend for 2-3 minutes. Store unused snot in tightly closed container. Discard after about a year or when it starts to stink. This can be safely added to any ceramic glaze, underglaze, or stain to improve brushability or dry strength.
Thanks! I so appreciate when potters are willing to share their process.
omg I love you
I teach classes and have memberships in my studio so you could come to Freeport IL and pot with me :)
This is so lovely, I feel like I can tackle this process now
Nicely done. Thanks for taking the time. Agreed, fun to learn and do.
great demo, many thanks!
Thank you!! Great video ! Great information!!
Great information!
Glad it was helpful!
The ink you made... is that an underglaze recipe? I have been looking for a good underglaze recipe for a while now. Thanks
When you say anti- Freeze are you talking about polypropylene glycol? Automotive anti-freeze? What paper are you printing on for your transfers and do you have a source? And thirdly have you ever tried the transfers as an ,"on- glaze" transfer. Im going to try this as an onglaze process on cone 6 majolica. I dont know how its going to go. Might have to spritz the glaze to dampen, perhaps with alcohol. But there is a window shortly after glazing wherecthe glaze is still damp but tough. Hoping for the best. Thanks for the vid.
Can you tell me what type of paper you printed to and any chance of seeing the transfer process to the clay
The paper is from a huge roll of paper that is used to cover banquet tables, I cut what I needed, but newsprint would work too. I currently don't have any wet work on the go that needs transfers, but I will put it on my list of videos to make when I do it next time :)
Thanks for watching!
Thank you very much for sharing your recipe. I love doing screen printing and have been looking for such a recipe suitable for ceramics.
Can I mix up a purple by using blue/red 50/50? Are there any colours which do not work? And how do you store it?
Do you blend it while it's boiling hot?
I blew the lid off my blender with boiling hot soup and narrowly missed getting scalded.
I am definitely going to try out you recipe. It looks just the right consistency! Thanks againr
Definitely be careful blending anything hot, I used boiled water but no longer remember how long it cooled if at all before I poured it in. When blending hot liquids its important to leave an opening for the steam to escape.
Ceramic pigments do not always behave like non ceramic pigments, since they are chemical reactions waiting to happen and can be modified by the clay body under them, by the glaze put on top of them, and the temperature they are fired at. The Potter's Answer™ is to TEST EVERYTHING with your materials and processes.
I store it in a closed jar on a shelf. CMC is organic and will eventually rot, so only make what you think you will use in a short period of time and the more you dip into it or leave it open to the air the faster it will breed microorganisms. Also some colorants seem to just feed microbes, cadmium yellow is one I have noticed likes to get stinky when mixed in glaze or underglaze.
Hi Stacey. Thanks for the video. Can the tissue with transfers on be stored once printed? Or does it need to be used soon after being made? Thanks!
Thanks for your patience, yes they can be stored as I made them, the "snot" (thick CMC gum solution) makes the print a bit more stable than plain underglaze. If you use a different recipe, experiment to find what works best. When you are ready to use them, lightly mist from a distance away to moisten the paper and underglaze and then proceed as though they were fresh.
what and were do you recommend buying for paper? I'm really excited to try this. thanks for sharing
Hi, I think that a lot of artists use newsprint, I used paper off of a roll that was designed to cover buffet tables, it worked well. I think a light duty cheap paper is best. Look around your home and see what you have, and experiment. I thought that the tissue from old sewing patterns might work, or wrapping tissue, but haven't tried it.
Hi there. Im from Brazil and im trying to put together a recipe to make my own underglazes. Some stuff im trying to work out how to get here.... But im just wondering what is the antifreeze stuff that u r using and what's it's function in the recipe.
Thanks for sharing ur work. Its very helpfull. See ya
It is Propylene glycol, and in the mason stain underglaze recipe I began with it serves to make the mix more easily brushable, the antifreeze is a little viscous. I suspect that for the screen printing you could leave it out and just use water, since you are adding so much CMC gum for that process. Here is the original recipe link for the underglaze - www.vincepitelka.com/wp-content/uploads/2016/03/Mason-Underglaze-Recipe.pdf
@@staceypottery3368 great. Thanks for clarifying. Cheers 😊
Hi, did you use a 120 mesh?
Go for 45T
