If you're after a stoneware clay that simply does what it’s meant to do — without fuss or unpredictability — PrimoPro RW1002 might be exactly what you’re looking for.
It’s a versatile, lightly grogged clay that suits a wide range of forming techniques and is used by potters at all levels. Whether you're teaching beginners, running large production batches, or just having fun experimenting with new forms in your own studio, RW1002 offers a dependable foundation that holds up across the board.

A Studio Staple for All Kinds of Making
RW1002 is a light buff midfire clay, made with 10% fine grog (0–0.2mm). That means it has enough tooth to give structure and stability when you’re handbuilding, slab-building, or forming larger pieces — but it’s still smooth and plastic enough for comfortable wheel throwing.

It's not flashy — and that’s part of the appeal. It lets your forms speak for themselves and handles whatever you throw at it (literally or otherwise) with a calm, solid presence.

“I describe it to students as a ‘light buff’. It’s not stark white, and it’s not dark or speckled – just that nice in-between that gives a really natural look. It suits lots of different styles of work.” – Julie Harrington, Wellington Potters Association

Suited to Classrooms and Production Studios Alike
RW1002 is popular with teaching studios because it’s forgiving to work with and stable through drying and firing. For beginners learning to centre or score and slip for the first time, it helps build confidence without causing unnecessary stress.

At the same time, experienced potters value it for its consistency, strength, and ease of use.

“We use RW1002 in all our throwing and handbuilding classes at Wellington Potters – and I use it in my own studio too. It’s reliable, easy to work with, and just really nice clay.” – Julie Harrington
