Return of the Vikings? 8th September

A table is set up in a barn. It holds a light, laptop and various finds. Some are stones, marked with a finds label. Others are in labelled bags. Some bags have been put into boxes to give them extra protection. The boxes are labelled glass, copper alloy,
The finds hut, where this blog was written. Boxes contain individually bagged finds, boxed by type - pottery, lead, copper alloy, etc. Other bags are still being processed. The large stones are possibly building materials.

Finds 

In the past week finds processing started in earnest, as stratified deposits were by then being dug across most of the site. In the first two weeks keeping on top of the objects coming from the site had only been a part time job: listing and packing the individual metal, pottery and glass finds that had been turning up. With the serious digging of stratified deposits, however, animal bone worth keeping for further study, started to emerge in considerable quantity. The midden (spread of dumped rubbish) in the main trench (Trench AG) was also being systematically sampled, producing tubs of soil needing processing. 

 

The animal bone and the soil samples form the two main strands of the finds processing going on site. The animal bone needs washing and drying before it can be bagged up for future study: when it will hopefully give insights into the diet and farming methods of the inhabitants of the site. 

 

 

 

 

 

 

 

 

 

 

The soil samples are processed in a flotation tank. A sample, held in a fine mesh, has water pumped up through it from below while being agitated and broken up by the hands of the operator. The flow of the water carries off light, organic, components (charcoal, grain, seeds and other plant remains), which is collected in a very fine mesh sieve. Meanwhile the bulk of the soil drops through the mesh into the bottom of the tank leaving the coarse residue of the sample in the mesh. This is mostly small fragments of stone but will hopefully also contain small animal and fish bones that would not otherwise get found. Both the material floated off and the coarse residues are then left to dry and bagged up for later sorting.
