While it’s perfectly safe to place your ceramics in the dishwasher, hand washing gently is preferred & recommended.
All vessels are sealed with clear glaze to make them water tight. Due to the pourous nature of stoneware, some sweating or condensation may occur at the base of your vessel. Be mindful when placing onto precious surfaces and if in doubt, place onto a table cloth.
Always place your ceramic piece down gently and avoid dragging or pulling them to move. This will prevent any scratching or marks on your surfaces.
