RM1507 Silica Sand 40s-90s (Medium) Silica Sand Grogs Added to a body, they help glaze fit and make the body more refractory. Grog (ground, fired body) is added to some clays to provide a proportion of fired and often refractory material to the body. This adds texture, along with bite, for better control during forming. The grog also acts as an opener and helps the clay to dry uniformly. As the grog is already fired it also cuts down on the overall shrinkage thus reducing problems of cracking and warping. Most are fired to high temperatures of at least 1300ºC.

Hi, I'm wondering if this sand could be used to rest (porcelain) pieces on the kiln shelf when fired to around 1240°C? To help pieces move as they contract and also to support rounded pieces as when fired. Or is there another product better suited for that? Thanks, Katarina
Katarina from Sweden
This would work but alumina hydrate would work better especially for porcelain as the alumina is much finer, hope this helps.

hi I'm looking at a bisque slip recipe that has epk , pot ash feldspar and silica ,, is this silica sand suitable ?

For the silica you would be best using quartz or flint.

Hi, I've been pursuing ceramics for about a year.. I'm interested in making a "Floating Blue" glaze, a la ceramic arts daily. Recipe I have calls for 20% 325 mesh silica. I assume this means very fine powder, such as passes though a 325 mesh screen, no? Can you supply this, or advise about it? Do you think I could buy your "medium" silica and grind it in a coffee grinder or mortar? With thanks, David

You require Flint or Quartz to use in any glaze recipe.
