The upstream brick floor has wooden bases with metal fixings, we believe a mixer stood here.
Mixers were used to remove tissue from bones using sulphuric acid to make fertilizer, we believe the brick floor is white due to acid spills.
The floor is adjacent to the trench and adjoins the hammer mill and cistern.
There are two long covered channels which run into the cistern.

An additional large brick floor was uncovered in early 2017 which goes over the upstream tunnel. In 2022 it was covered with soil to protect from frost damage and will become a Cornfield Flower area as part of our Wildflower Meadow project.
