This Vertical Tile Setter makes firing large quantities of tiles a breeze! Fit up to 8 tiles sitting up vertically in the slots. The maximum size tile we recommend to use with this tile setter is a 6" Tile. Make sure the back side of your tile (the part that will be leaning back) and the edges of the tile are unglazed to prevent your tile from sticking to the setter during firing.
