Cut the thermal (laser) design to fit the unglazed tile
Rub a fairly generous amount of the ITS solution on the front of the thermal (laser) photo
Pllace face down on unglazed tile and rub until well-adhered, then bake in a 325F oven for 30 minutes
The paper will be firmly stuck to the tile after baking
Gently rub the paper off, leaving the ink design - you can see that it came off around the edges, but I think if I had torn the edges to make them softer, this might not have happened.
Coat with a clear acrylic spray to protect the tile
