Ceramic Sealer

Ceramic sealer is a liquid silicon dioxide which can be applied to all unglazed, stable, porous surfaces; bisque ware, vitrified ceramic ware,  fired clay bodies (pit, smoke, saggar, barrel, naked raku) to create an invisible, protective barrier against moisture.

Can be either a brushed or sprayed on. Brushes can be washed with water.

It will burn of if fired.

It is non-toxic and non-hazardous. But we still advise caution when using this for dinnerware, as this has not been tested for dishwasher/microwave use and as a long-term seal.

Dries clear and matte.
