Axella Denmark pottery has quite a distinctive 1970s look about it, and as far as I have seen appears to be all stoneware (Stentoj)
The pottery began around 1970 in the town of Norresundby (Near Aarhus) Denmark, being founded by Aksel Larsen. It had several name changes during its short operational life starting as Axella Design then around 1978, changing its name to Axella Ceramics and then back to Axella design. It closed in 1987-8.
Jens Jensen, and Jette Helleroe both worked there for a period – in fact the majority of the work that you will come across from Axella, is work by Jette Helleroe – her stunning series of pendant light shades and lamps for Axella.
Thankfully, it seems that all Axella works as clearly stamped with an impressed stamp, and are often found with a foil label still. The work by Jette Helleroe for Axella is signed by her in addition to being stamped. Many pieces also have a stamped number – which I am guessing is the shape or form number.
