Darrel,
This glaze contains 65.72% grit which is dense. You can mix 10,000 grams into a 5 gallon bucket.
This is not always true if you are using light fluffy chemicals. But that much grit makes it an easy fit.

I got this fancy glaze batch size reference sticker from glazecal.com when I was at NCECA this past year. I like it because I always forget.
Of course the weight will vary according to what type of materials go in.


Sticker says:


"8,000g - 5gal container
3,000g - 2gal container
1,500g - 1gal container
500g - 1 quart container

Start with a batch size you know will fit into your container. Gradually increase for each glaze."

dear percolator,

I have used Arbuckle's glaze and it fits in
To five gallon buckets because Frit is a dense material.
So do several other majolica glazes using high Frit contents.
Ps. I have been going to NCECA since 1971, served on the board in the 1990s and know for a fact that
This glaze will fit 10,000 grams into a five gallon bucket. This does make a very full bucket but I mixed it for a tile glazing workshop so it was good to have a full bucket.

The sticker you are referring to is an OK and just OK rule of thumb with a few exceptions...dense Frits being one of them. On the other extreme, ash glazes or Magnesium carbonate glazes may not fit 6000 grams into a 5 gallon bucket because the material is the opposite of dense. The two other examples are light and fluffy. This changes their mass in a five gallon bucket. this has been discussed on this forum previously.

Here is additional information from her web site. Your recipe is slightly different going into 2 decimals.
http://lindaarbuckle...handout2007.pdf

When preparing the surface , sand any blemish and wash the piece with diluted vinegar and water.

After applying the glaze, and after it dries, smooth out any thick spots or pin holes.

Watch her video online. There are several sites and one on CAD.
