Darvan 7 Ceramics

The typical method of using sodium silicate and soda ash to deflocculate porcelain or clay casting slips can be a finicky.

Darvan 7 ceramics. The smooth on rep also sent samples. Very soon i had samples of darvan 7 and darvan 811 i n my studio. If you always mix your terra sigillata in the same container place a permanent water line on the side of the container so you don t have to measure the water every time. Like 811 and 812 this poly electrolyte shows the advantages mentioned above.

Darvan 7 is a deflocculant that is similar to sodium silicate. Think it was don frith who introduced darvan and smooth on to the studio ceramics world. However unlike sodium silicate darvan 7 does not erode plaster. 7 is a high molecular weight long chain polymer that has been used successfully as a general purpose dispersing agent for both ceramic bodies and glazes.

7 is a high molecular weight long chain polymer that has been used successfully as a general purpose dispersing agent for both ceramic bodies and glazes. If you re a ceramacist you know that properly tuned liquid clay slips and glazes are critical to successful ceramic and pottery manufacturing. Darvan 811 is a deflocculant that is similar to darvan 7 but is more. Usually darvan 7 is used for glaze deflocculation and darvan 811 is used to deflocculate casting slips.

Darvan 7 is the industry standard dispersing agent for ceramic slip and glaze. Smooth on is a urethane rubber casting medium being full of myself i called these companies and told them that i was mold making company. As a deflocculant darvan 7 weakens the electrical attraction between clay particles and thus acts as a thinning agent in slips and as a general dispersing agent for clay bodies and glazes. Used as a deflocculant.

There is a great explanation of it at tony hansen s ceramics materials site. However unlike sodium silicate darvan 7 does not erode plaster molds. Darvan is a liquid deflocculant that is often preferred for use with plaster molds because unlike some other deflocculants darvan does not degrade the plaster.
