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.

It was there that we really first came in contact with the work of Shoji Hamada, who was Bernard's best friend from Japan, who had come from Japan back to England with [Bernard] Leach when Leach was establishing his pottery.

If [Bernard Leach] didn't like the drawing, he'd X it out and do another one and change the form a little bit. And when he was all done, he would stuff these pieces of paper in his pocket and go off to the pottery, and when he wanted to make pots, he would then take these out and he'd begin to produce the pot that he had designed on paper in front of us.

This is something which I think I have been able to communicate to both people I have taught and people that have purchased our work since that time, that they all say, it's so nice to have these pots with us all the time and to eat out of them and be in direct contact with them in our homes.

I was a very hard-edged geometric painter, strongly influenced by [Piet] Mondrian and [Theo] van Doesburg and that sort of thing.

If you take Lucie Rie and Hans Coper, their work didn't even relate to what we were trying to do, because they were moving in a different direction, both of them coming out of Europe and the Viennese school of design, which Lucie came from, and Coper learning from Lucie and then springing off on his own when she encouraged him to explore more widely. So he created his own work instead of just working for her and doing her forms. So that was a wonderful thing.

If you didn't know what you were trying to do, [Robert von Neumann] wouldn't say a word. He would just turn and walk away. So you very quickly learned to think that you'd better be attempting to do something in that painting class.
