New glaze surfaces

  •  

Over the summer I have been working with some students developing different kinds of glaze surfaces for stoneware temperatures.  I thought it was important to put my money where my mouth was and use some investigations of surface on my own work.

I was trying to explain that using commercial stains on their own can lead to work that has a very similar palette to other makers, and that with testing, and possibly adding pure metal oxides, surface modifiers, and opacifiers, you can develop your own personalized colours that are your own.  The following three glazes are the end point of these investigations.
