The firing of celadon glazes

  title={The firing of celadon glazes},
  author={Paul Berg},
The celadon glazes owe their color to the presence of Fe 2+ , obtained by firing in a suitable reducing atmosphere. From standard free energies the optimal composition of the furnace atmosphere to accomplish reduction of Fe 3 O 4 was calculated, and it was determined that a volume ratio H 2 /H 2 O in the furnace atmosphere should be kept at a value slightlyabove 0.1. Firing experiments were performed in which the furnace atmosphere was controlled by introducing dilute aqueous MeOH solutions… CONTINUE READING
