I haven't been keeping up with events! Test Pit 2 petered out at around 40 cm. I scraped the bottom, measured the depth and then filled it in (and sowed some grass seed on the top).
The pottery finds are laid out above. Level 4 included some older looking pieces, including the largest piece (top right) which was of a colour and fabric I haven't seen before. More about that later.
One piece missing from the photo is a single rim-piece of "local coarse ware". It is identical in colour and fabric to my other late Iron Age pieces (see following entry). So, true to form, I always find at least one piece of this type wherever I dig in the garden.
The piece I featured in my previous entry seems similar in fabric (and inclusions) to two pieces of a gritty nature that have a green glazed finish. Although these have signs of a grey core, the fact that they appear to have the same brown pebbly inclusions makes me think that they are related. I thought that the orange piece I wrote about last might be older than this.
Oh for a pottery expert I can run to with such things!
