The salt kiln had been out of action for a while. Ray had bought it down in Devon a few years ago, and transported it, in pieces, back to Cumbria!
The whole thing had been reconstructed on the Solway site but the archway had collapsed shortly afterwards and it had stood unused since. During a previous visit, a few of us from the College had volunteered to get it rebuilt and back up and running, and eventually we got ourselves organised to go and get the work started.
Brick mayhem
The first job was to dismantle the existing kiln to below the start of the arch, and to sort and clean the bricks. The bricks used were fire bricks of various kinds. I must admit to having known little about the construction of outdoor kilns before this weekend, and I still have a lot to learn! For a start, I was amazed to find out how many different kinds of bricks there were. The kiln has a inner lining of high firing bricks that can withstand stoneware firing temperatures (up to 1300 degrees centigrade), and then an outer lining of insulation bricks of various kinds which have a lower temperature threshold and are used mainly as an additional lining to prevent heat escaping from any gaps in the course of fire bricks.

Whilst a group of us were cleaning and sorting the bricks, Andrew (our star technician) and Steve set about making the former on to which we would construct the brick archway:
Eventually the arch was ready for positioning and it was all hands to the job to get it into place. People of all heights were needed - it was a bit of an up and under job!

Once positioned, it was a case of starting to build the archway up against it, using the 'arch bricks' - these are tapered at one end and there were 3 or 4 different sizes with different degrees of angle... John, Steve and I had to learn quickly how to fit them together for optimal usage of the limited number of bricks and also to ensure a neat curve that would hopefully meet evenly in the middle.... We used fire clay as mortar where and when it was needed, but generally the idea is not to mortar the bricks in a kiln like this. The kiln needs to be able to expand and contract during firings and mortar either prevents this, or just falls out in the process of the kiln's movements.
Steve's a natural at this...
