Kevin, are these measurements? 46.0,300 etc.? Does one mix together and add water? sorry if this is obvious, but I am new to this.
Where is the best place to buy these materials?
Typically your local clay/ceramics supply due to weight/shipping. But places like Clayscapes Pottery do ship materials.
Hi if you look at Sheffieldpottery.com they have a lot of items with free shipping, not sure about raw materials. Do live near any distributors? Sheffield is in western Massachusetts, Bailey pottery in near Troy New York, Portland pottery is in Braintree mass, I’ve bought my raw materials from each of these places. Where do you live?
Jess has a class out there about mixing your own glazes that will explain everything.
How do you go about adding colorants, how much? Are mason stains colorants?
yes! Mason stains are colorants, although there are many colorants that are not Mason stains. How much to add to a batch depends on the result your looking for, which may differ depending on the specific clay body your looking to apply to it.
thank you --- is this a zinc free clear glaze?
I fire to cone 5, can I still use this glaze? Will it be food safe?
wish 2167 was for sale. I am so new to all this Jess is my Godsend LOL So when she says she uses something I am like....ok buy it now HAHA
oh ok so I'm not a total idiot haha.. I've been looking for her clear glaze for sale and couldn't find it. I figured they'd at least sell the ingredients and just add water maybe? for us noobs? Maybe they do and I just haven't come upon it yet!
I wish they sold it, would make a fortune LOL
I am in the UK and EPK is something I am not familiar with. What does it stand for? Many Thanks. Nadine
It's a kaolin (Edgar Plastic Kaolin).
Quick question, when I go to order silica there are lots of options... is it silica sand or flint/silica or something else?
Thanks so much!
Also are we talking about grams in the recipe?
Flint/silica. It’s not silica sand.
I only use this glaze as I have had a lot of problems with underglaze running and other problems.
Thanks so very much for providing this recipe.
Go to know, thanks Susan.
Thank you for this recipe - beautiful clear gloss with NO cloudiness, even over b3 dark brown clay!
Hi sorry if this is a stupid question, but can this glaze be used on earthenware too? Thank yiu
This is a cone 5/6 glaze so it'll need to go hotter than your earthenware probably wants to go.
Is this recipe based on a 5gal bucket (10000g)?
Still curious, want to make a batch and wanting to know what size bucket to use
Think of the values as percentages, so you can make any size batch you want. Jess typically does a 1000g batch and that works well into a 5 gal bucket.
Hi Kevin, do you mean 10,000 g batch? I usually do about 3,000 g for a 2.5 gal bucket. 🤗
Yep. Coffee wasn't working yet this morning...
Should the silica be 200 mesh or 325 mesh?
Jess said 325 mesh in a live broadcast.
325 is what you really need for this.
Hi, is that Minspar 200? Is there a substitute? I have Custer Feldspar and Mahavir. Thanks!
