Alumina Hydrate

ALUMINA HYDRATE (ALHYD) is preferred over the calcined form in a glaze for adhesive and suspension qualities. Commonly used as a kiln wash in salt fire operations and as an aid in reducing crazing. Minimum order quantity is 1 lb.
Alumina Hydrate is used to support Silver-Clay during firing, Either make a pile on the shelf or put it in a little unglazed bowl. Alumina hydrate is also called glass release or glass kilnwash as glass will not stick to it during firing. Using Alumina Oxide will avoid the boiling off of water in the hydrate.

Crocus Martis "Purple Iron" Bayferrox180

Crocus Martis (Miconized iron oxide).

“Natural Crocus Martis (Purple Iron Oxide) is unobtainable, (either because of politics, or the known seams have dried up no-one seems to know for certain) the only stuff we can get now is synthetic, it seems OK.” Steve, from Bath in the UK


This is the truest statement about Crocus Martis I have found. The Crocus Martis is a synthetic iron oxide that is “micronized” the Bayferrox 180 NM is the finest particle size and that is what gives it the bluish tint. It is just pure iron oxide Fe2O3.

Shigaraki Ware

Recognized as one of Japan's six old kilns, the history of Shigaraki ware dates back some 1,200 years to the Nara period (710-794).

There are three points to look for when judging the color of a wood-fired, ash-glaze Shigaraki pot -- the overall color, the glass beads and dribbles formed when the heat in the kiln melts particles of feldspar in the clay, and the scorches that come when the pot is blackened by ash.
