Maltby pot, stoneware, drip glaze, date?
8” vase / flagon.
I’m not well up on the development of his work. Sadly I haven’t found many pieces so far and I wish I’d bought his sculptures when they were offered to me.
Would this likely be something he would have made in the 1960s ? 1970s? 1980s?

Bit if a mess this one! He started Stoneshill pottery in 1964. Which of course was very much standard leach style stuff. This one looks as though he was experimenting a bit. Late 1960's or so?

Thank you. I quite like the glazing dripping down and the unglazed showing through. I guess potters make all sorts of pots discovering their style.

The glaze is designed to crawl like that. I'd guess he was making them between his Stoneshill domestic ware phase and his slab built stoneware Art pottery phase.
