Site works - 20th and 21st August
We've completed the arches and have started work on the dome. The key thing for the coming week is to keep the brick rising walls ahead of the dome, as we cannpt complete the dome until the walls are in place.
We used the lower course of the arches as a test for getting the placement of the slips right for the dome - and so used casting plaster to allow us to perfect the mixing of small amounts of plaster (enough for one slip) to the correct consistancy quickly. This will be critical for the dome as we will be relying on the plaster to set quickly and to hold each slip in place as we work upward.
