A must-have: Laboratory variable speed propeller mixer

Wednesday 18th February 2009

If you are at all serious about testing glazes and insight-live.com/glossary/11">clay bodies, you need one of these. There are other methods, but nothing else comes close to this. It is the most valuable and frequently used tool in any ceramic bodies and glazes testing lab or classroom. This is the Lightnin brand, they are expensive but high quality. This is a 1/20 hp variable speed unit, it could be $4000 new! But you can get them used on ebay.com (the industrial mixers are most common, lab mixers are jealously guarded). This one uses a 7.9mm dia (5/16") shaft. We adapted a mount (to give it vertical adjustment) from small drill press.
