The back of each tile is marked USET. Each tile measures 6" square x 1/2" thick.
Each tile is decorated with a central radial flower. Most of the mortal has ben cleaned off of the backs and sides. I have also wiped most of the soot off of the faces. Glaze is crazed on all tiles. One tile, the one in the upper left hand corner of image 3, shown in image 4 has a crack running across a corner. The corner remains intact and could be used, but it does have damage. One other tile does have a small chip in the glaze. This can be seen in image 8. Additional pictures and measurements available upon request.
