Welcome to the Stretch Lenny Pottery Studio website. Here you can get a feel for the hand-thrown ceramic vessels of Martin Harris. Based in Windhoek, Namibia, Martin works with stoneware clay and ash glazes to produce finely crafted bowls, mugs, dishes and other distinctive utility ware. Martin started throwing on the wheel as a high school student and counts amongst his early influences British studio potters Bernard Leach and Michael Cardew. After retiring from a 40-year career as a civil engineer in Namibia, Martin returned to his studio to continue his fascination with thrown stoneware. He continues to experiment with ash glazes made from Namibian hardwood, fired in a reduction atmosphere, making pieces which vary in texture and reflect shades of grey through to green with hints of oxidized iron.
If you would like to receive updates about his latest ash glaze experiments, and be the first to hear about newly fired works, please sign up to our mailing list. Feel free to contact us to find out what we have in stock.
