Stoneware glazes and the "Super E"


TesttileThis workshop is suitable for all of you who would like to develop a deeper understanding of glazes so that you are able to develop those glazes that you want with a reasonable effort and to fire it successfully. It will be the second edition of my glaze seminars for the ICS Hungary. The first edition took place in 2014, and you can read the old announcement as well as the summary here. There are also a lot of pictures giving an impression about the place and the kiln we used.

Reading the old announcement would also give you a good idea about the workshop content. But I can make it a bit shorter here: My speciality is the combination of volumetric blending and computer aided glaze calculation. These are both fantastic tools in itself, but the combination of those two methods accelerates the learning speed dramatically. And what sounds dry, complicated and far away will be useful and near after you've done it once or twice.

After the workshop Patricia Shone wrote: "I am finding all that you taught us on the course very useful. I am surprised that I have remembered so much! And my kiln firing is much faster and hotter now."

Super E KilnThe results will be woodfired, and, depending upon the number of participants and the amount of work, also gas fired. I hope on many participants because the more people are there the more experiments can be made.

Last time we fired Kusakabe-San's Sasukenei kiln, this time it will be the Super E, which was built in 2015  during a workshop led by American kiln builder and potter Fred Olsen. For me this will be the first time to fire this kiln, so that will add another adventure to this week of explorations.

I'm very glad to be able to hold this seminar at the ICS. It is such a wonderful place with fantastic possibilities. And it will be in spring, the week after Easter in 2017. Further informations are provided at



The workshop will be held in English. For reservations please contact the ICSHU, Steve Mattison.
