Would not recommend using a glaze with 40% barium carb, especially for functional

@ImogenBIf you use this you need a liner glaze. Sorry, I'm so used to using liners, I forgot to mention.

 

Any clear cone 6-8 glaze would work. There are plenty in Britt's books.

Brandon,

Thanks for your reply.

I was wondering if it was stain. I'm yet to test one out, I shall get experimenting.

This is the work of Helen Levi, I would think she tests her work to see if it's food safe, so i'm sure it can't be saturated cobalt as that wouldn't be safe.

And thanks for the extra tip about amounts, i'll make sure to larger amount when ordering.

Here, I just came across this, looks nearly identical.

 

I saw it and immediately thought of your posting. Give it a whirl and let us know how it comes out.

Also, You can probably squeeze this in a cone 8 load. If you want, I can make a test of it, Im getting rid of my last bit of HF clay, and don't have enough glaze for all the pieces

I'm a new potter, and looking into making my own glaze. I'm concerned about how to make such a bright glaze on a stoneware body, most likely firing to cone 7/8 and that is this bright in colour AND most importantly food safe. I'm learning the chemistry behind it but ingredient suggestions might be helpful or just any help. 

 

That is most likely a stain or a very saturated cobalt. Most saturated cobalts are dark blue, I have never seen such a light blue like that with cobalt.

 

Look at these mason stains below.

Note: Stain are usually between 3-10% in glazes. If you want to make (say a 5000g batch) you are better off getting 1 lb of stain, many people (myself included) often get 1/4 lb and it's a few grams off, and there is not enough for a batch.

Simon is more comfort food than learning experience, I'll give you that.  He's a comforting figure you can tune into for some soul time.  He has about 100 videos on making tankards but his British charm and soothing voice are something that I tune into just for fun.

There are days where I will have my laptop sitting behind me and have his videos playing while I throw.

 

Something about that damn voice, makes you feel comfortable on the wheel.
