|I visited this monstrosity in 2007 and when I first saw the building above I said, "where's the kiln" and my host said, "That's it!"|

An American potter who attended the 2004 German kiln firing told me that when the kiln was being salted, people started coming out of their homes and collecting around the kiln. He asked what they were doing and was told that traditionally people came to the salting for health purposes, that they thought the salt was beneficial to their health! In Europe now, most salt kilns are required to have a scrubber on their chimney in order to clear the fumes before entering the atmosphere. Here in the States we do not have regulations on salt kilns as much, and for the comparatively few and small salt kilns that there are, the amount of gases released is minimal. Historically, in parts of Europe there were regulations requiring potters to be moved and kilns to be put in other regions because people complained about the smoke and cloudiness.

1. Bring kiln to temperature (2,200-2,300 Fahrenheit)
2. Insert salt into kiln (various methods)
3. Salt turns into gas which adheres to the clay body of the pottery, making a glaze.
The German kiln firing in 2004 turned out pretty well! They had a mishap in the center of the kiln, where the floor collapsed partially, but all in all the results were good.
