Making my own home-made fired speckle for cone 6

Tuesday 24th March 2015

I need to control the particle size of this product. I have already smashed it up and am now sizing it. That involves getting what I can through the screen and then going at the larger-sized particles with the pestle again. This has to be done carefully, or too many fine particles are generated. I use three screen sizes in this procedure to control the distribution of particle sizes in the fired product (to more closely match insight-live.com/glossary/125">reduction-fired ware). This method is also good for making your own grog, where control the distribution of sizes is important.

This can be a dusty procedure and those particles are angular and sharp and high in heavy metal, so it is best to do this outside in a breeze or with a ventilator and mask.
