Robert von Neumann taught painting, and when I finally got into a painting class of his, he reacted in much the same way.

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 ].

In working on a drawing or a painting, one can rework and rework and rework and change ideas until you get it the way you think is right at that time. With clay that's not possible. You either succeed the first time, or you should wad it up and start over again, because you can't mess around with the clay and still have it fresh.

In looking at these pots at the Field Museum, Alix [MacKenzie] and I both came to a conclusion individually but also collectively that the pots that really interested us were the pots that people had used in their everyday life, and we began to think - I mean, whether it was ancient Greece or Africa or Europe or wherever, the pots that people had used in their homes were the ones that excited us.

It was a figure painting class, where you had a model, and [Robert von Neumann ] would wander around and he'd come up behind someone and say, "Well, what are you trying to do?" And if you told him what you were trying to do, he would then proceed to discuss this with you and suggest things that you might look at and ways in which you could improve what you were attempting to do, etc - never worked on your painting, never touched your painting but talked extensively about what you were trying to do.

Alix [ MacKenzie] had stopped teaching because we had a child and she stayed home to take care of the baby, and I taught.

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.
