Some years ago I was working on some forms which were vase forms with a fairly narrow base, and it was after [Hans] Coper had died that I saw an exhibition of his, a catalogue from an exhibition, and he was showing some forms which were made by cutting and joining a lot of different parts together to create what he called a spade form, which you can imagine looks a little bit like a shovel upside down.

Looking back on it now, I understand why that was not possible [to express ourselves], because the pottery employed a dozen people, not all of whom are making pots. And these people had families, children, and they had to have a wage that would allow them to raise their family and they had to get a paycheck every Friday afternoon. So if we had not made pots that would sell it, would not have been possible for these people to be employed.

We moved up here [to St.Paul with my wife] and started to teach, we very quickly found out we were not equipped either to teach or to run our own pottery, and so we decided that we had to have further training.

We asked a lot of questions and we watched everyone who was working in the studio. And we had an opportunity to sit in on discussions, aesthetic discussions at the pottery, which took place generally over tea breaks in the morning and afternoon. So we learned a lot just from being around there [with Bernard Leach ].

I think back to some of the pots we made when we first started our pottery, and they were pretty awful pots. We thought at the time they were good; they were the best we could make, but our thinking was so elemental that the pots had that quality also, and so they don't have a richness about them which I look for in my work today. Whether I achieve it all the time, that's another question, because I don't think a person can produce at top level 100 percent of the time.

[My pots ] are not like [Hans] Coper's at all, but the idea came from seeing catalogue of his work, although at the time we knew Hans, his work was nothing like that.

Eventually I gave up teaching at the St. Paul Gallery because of disagreements with the philosophy of that museum, and I got a job at the University of Minnesota, which was very fortunate because it was a part-time job and that gave us a great deal of time in our studio to work together and to make the pots we wanted to make.
