not much clay in that glaze... just the bentonite. have you tried the
product "flocs" it's supposed to help keep stuff in suspension.
might help. or try to reformulate using some clay? some glazes
without clay work great some are terrible at staying in suspension.

Has anyone made Harding Black's "Orange Peel Oxblood" glaze?
I just made it and sieved it about 10 times but the ingredients still
settle to the bottom like cornstarch almost. SOOO thick -- and there is
plenty of water so its not a matter of dispersion of ingredients to
water. I'm just wondering if anyone has had the same cornstarchy
experience with it. Its NOT because of the bentonite.
Here is the recipe I got off of Baylor University's site. Harding Black
donated all his glaze research notes to Baylor.

I used Minspar 200 instead of NC-4 Feldspar
Minspar 200 -- 55
Whiting -------6
Silica ---------- 20
Frit 3110 ------15
Zinc Oxide ---- 4
total ----------100
add
Tin Oxide -------- 1
Copper Carb --- 0.8
Bentonite --------2

Hi DJ,
It's the 3110 - lots of sodium coming out and no clay to help the suspensio=
n.
You could try adding some Epsom salts.
Depends on how much you mixed up - dissolve two table spoons in half a
cup of water - heat - microwave will work well - stir - heat - until
all salts are dissolved.
Store in a squeeze bottle with a cap. Add to glaze a drop at a time -
stir - wait 10 min stir again - eventually you will get some suspension.
Wouldn't hurt to add another 1% bentonite I suppose?
