Here's a firing I did last weekend, with a whole bunch of salt glaze tests, using the colourants out of my stoneware glazes in a more suitable salt-glaze slip.

| Test salt kiln with chimney in place. The chimney height should be approximately three times in height from the diagonal width of the kiln chamber to get the best draw. |

| A view through the spy hole of some small test pots and cones 9 and 10 | 
 | 
|  | 
| Adding some clay wadding pads to the base of all pots. The wadding is the same as my shelf wash (but with more water so its a kind of a slurry)  and consists of 50 percent Alumina and 50 percent Kaolin which repels the salt quite well and doesn't stick to the bottom of the pots. | 
|  | 
| Looking through the spy hole, around 800 degrees C |

| Opening the kiln the next morning to check out the results |
