Perlite and clay slip are mixed together and placed between the bottles. When I dug the clay to make the slip I realized it was actually the clay that I had used for my test last year. It is from down lower than the clay we used for the bricks and has a higher clay content. Notice the difference in color. I hope the bricks are OK but David said he would go on strike if I made them over. I think they will be OK.
