Sacrificial Plates

Sacrificial plates are clay tiles specially prepared and fired to place under your ceramic pieces when they are glaze fired. They are placed there by the kiln packing team in an attempt to prevent any glazes from running off your piece and onto the kiln shelf. They are a protective measure to promote the longevity of the shelf’s life as glaze run-off is extremely hard to remove, sometimes impossible, and the kiln shelves are very expensive.

Remember when you are glazing your work, leave at least a 5mm clear space around the bottom edge with no glaze. And make sure you wipe the bottom of your work clean from any glaze. If you are unsure ask either the supervisor or one of the glaze team for advice.

As part of the new kilns’ processes all items to be glaze fired will require a sacrificial plate under them.

Uh-Oh. Should've used sacrificial plates.
