Inside the Kiln

Harbison-Walker kiln interior — Harbison-Walker kiln interiorLibrary of Congress HAER PA-242 l09

This is what you faced if you took a kiln job at Harbison-Walker, extreme heat, constant monitoring, days of firing to get the brick right. The work was critical, dangerous, and hot beyond what modern workers would accept.

Checked against the record. Photograph citation corrected from an internal credit line to the Library of Congress record, so a reader can open it. The text on this page is descriptive and still carries no source of its own; that is the next pass, not this one.
