I enjoyed learing how to mark the finds today, each piece has a code (relating to the dig) drawn on with pen and ink. They may also have subsequent numbers added by the museum they end up in. I have often been intrigued by these markings and this is something I have been considering using in my own work. I could perhaps use a code that relates to where the sherds were found – and ordinance survey grid reference, or to the number of pieces made or glazes tested. The images below are of some of the pieces I have marked at SWARCH.

Glazes
Stoneware glaze experiments so far
Recipes:
Emmanuel Cooper Smooth White 1260 (from old edition of The Potter’s book of glaze recipes pg 164)
Feldspar 45
Dolomite 20
Whiting 10
Ball Clay 25
I then tested it with 10 different oxides:
- Copper Ox 4%
- Cobalt 1%
- Tin 8%
- Iron 7%
- Chromium 1%
- Nickel 2%
- Rutile 8%
- Manganese 4%
- Titanium 5%
- Vanadium 5%
Which were then all tested over each other (Greg Daly colour blend) which gave the 66 results in the picture. These were then tested on porcelain.
