liquid quartz

what is it?

The first unglazed ceramic sealer of its kind, Liquid Quartz is a non-toxic, water based, permeating sealer that allows you to turn your unglazed ware into food safe, waterproof, & highly stain resistant functional tableware. Liquid Quartz can be applied to all unglazed bisque ware, vitrified ceramic ware (being still slightly porous) & alternatively fired clay bodies (pit, smoke, saggar, barrel, naked raku) to create a completely invisible, long lasting, breathable (yet water impermeable) protective barrier.

While Liquid Quartz is NOT for use over glazes, it has become very popular with artists who glaze only part of their work, to seal the unglazed sections & prevent staining from lips & fingers, & water seepage from washing. Liquid Quartz will not effect the glazed sections of your work, it will simply bead & run off a non porous surface. We have also had reports of great results sealing leaky glazed wares from woodfirings, & betwen the cracks of crazed & crawled glazes from electric & gas firings.
