Bexley YAC's bonfire!
The June session of our Bexley YAC was on site having a go at some potty experimental archaeology! We thought about early pottery and we wondered how decorating pots started.
Giving our pots the slip!
We had some biscuit-fired pots and some slip (which is liquid clay). We had to find something to decorate the pot with (a stick or fingers) and we also had to mix the slip with water until we thought it was the right consistency. Some of us put a layer of slip on a leaf and stuck it to the pot to see if the leaf would burn off and leave a leaf pattern.
The pots were then put into the fire. For how long we wondered? We took them out when they looked done and left them to cool. We had some interesting results. If the slip was thick it mostly crumbled off. The thin slip seemed better. All the leaves burnt off but not all left a print, some crumbled away with the slip. The pots in the centre of the fire were more successful, but burnt the pot, although some in the front of the fire were also very successful.
We had a great time experimenting and it was a good excuse to have a huge bonfire!
