earth kiln
the clay-in-formation felt like it was both of the world and of me. the boundaries of my haptic self expanded to include the changing clay form and became indistinct, making it difficult to distinguish me from not-me. my eyes however lagged, still tending to see the clay as something beyond me.

lossenham pottery project 2025 - year three
this year’s pottery project is being led by philip warren with a little help from russell burden
in september we executed a successful second firing of the twin stoke hole earth-kiln to plus 1040ºc (images below)
also see below for part II (2024/5) and part I (2023/4)
and here to view philip’s ongoing work for part III (2025/26)
lossenham pottery project - year two
location: lossenham farm
duration 2023 to 2025/26
project leads: russell burden & philip warren
funded by: the janus foundation
supported by: rye museum
year two objectives:
• a clay sample survey of lossenham
• local clay & slip material testing in a controlled kiln environment
• testing low temperature earthenware glazes
• a hybrid earth-based kiln to test early kiln architecture and various firing methods
• contemporary ceramic pieces made with lossenham clays
• exploring the making techniques of medieval kent and sussex pots
• experimenting with decorated tile production
• work developed by other artists
• open access project documentation

project lead: russell burden
head volunteer: philip warren
volunteers: eight
studio facilities and support: alan parris & billy byles at aylesford pottery
