This 3.5" wide teabowl is VC72 with no colorants.Hard to see in this white-on-white context, but a very nice surface.
This 6" wide bowl is glazed with Oatmeal, from Mastering Cone Six Glazes. Went to cone 7, so it moved a little.
Insidde of the cup at left. DK11 WSL with 5% Rutile 2% RIO and 1.5% TiO2. I like this for a liner if it proves to be safe.
This is the Falls Creek Shino recipe with RedArt. Not terrible, but not shino either;-). This batch always crawls on edges and looks like paint on the ousides of pots. Looks ok on the inside. 17" bowl.
Licorice. What a surface. next to the 6.5" bowl is a test tile of Old Black Magic ^10 on Porcelain from several years ago.
This bowl is glazed with 75/25 wet mix Nutmeg./WSM, thick.It would probably be darker if it were thinner
This is Tom Buck's Cream Breaking Red, kind of thick. I like this glaze a lot- it's very rich. I will fire some additional tests with a thinner glaze coatiing to see if it breaks more,
7.5" wide bowl- Licorice outside, 60/40 mix Nutmeg/WSM inside, dip of WSM on rim. Sort of a post-millenium Hull China vibe. (My Dad did work in the pottery in East Liverpool), Inside of bowl is at right---
This is a 50/50 wet mix of Licorice and Nutmeg (does that sound good?)Makes chocolate. Very smooth and hard.
VC 62 5% rutile 2% cobalt carb. Pretty dry but a nice matt surface. More boring when the rutile is sieved than when there are some bits left.
VC 71 with 5%rutile and 3% copper carb. Inside VC71 with no colorants. Bubbled on the lip where there was an overlap.
This teabowl is John and Ron's Clear Glossy Liner; inside with no additions, outside with 10%Zircopax and 6%TiO2 not much happened as a result of the additions.

Here are a few Cone 6 oxidation glaze tests. Some recipes are from Cushings Handbook (DK11White Satin Liner; VC 72, VC 71, VC 62-all with various colorants), Mastering Cone 6 Glazes (Licorice, Clear Glossy Liner, Raspberry, Oatmeal) Michael Bailey's Cone6 Glazes (Orange Iron) , as well as the glazes Nutmeg and WhiteSatin Matt from the "woodfiredlook" article in last month's CM. I also tested some ClayArt recipes- Tom Buck's Cream Breaking Red, Falls Creek Shino. I won't post the bailey/roy/hesselberth recipes here, but as the others seem to be pretty much PD, I'll post them, as I used them. So far I have done the standard freezing/boiling tests on evrything but the greens and blues, and haven't seen any crazing. Have run Licorice, and the various liners through ten dishwasher cycles with no perceptible effect. Most of these pots are thrown with Miller 55 cone 6 stoneware. Any pot that says white stoneware in standard 181. I tested the Bailey Iron Orange with different levels of RIO- with 3% it was a nice pale yellow translucent over Miller 55- I lost those photos somehow, I'll try to reshoot if I have time. Below are the glaze formulas not in Ron and John's, Mike Bailey's, or Val Cushing's books. Under that are many photos of pots.Firing schedule was preheat 7 hours @150; 60/hr to 200; 400/hr to 2000; 150/hr to 2194-hold for 20 min; fast cool to 1900; cool at 125/hr to 1600; off.
These are the cones- 5,6,7. Firing went to Cone 7 flat and nearly flat, I'm pretty sure they went all the way down during the soak.
