NOTE: DURING SHIPPING THE MUFFLE MIGHT ABSORB
MOISTURE FROM THE AIR. SO, IT IS RECOMMENDED
YOU HEAT THE MUFFLE TO DRY THE MOISTURE
BEFORE FIRING ANY PORCELAIN. TO DRY THE MUFFLE,
SET THE IDLE TEMPERATURE TO 400° C (752° F) FOR
ONE HOUR AND THEN 600° C (1112° F) FOR ONE HOUR.
IT IS ALSO RECOMMENDED YOU KEEP THE FURNACE
ON WITH SUFFICIENT NIGHT MODE TEMPERATURE TO
PREVENT MOISTURE FROM ACCUMULATING INSIDE
THE MUFFLE. THE RECOMMENDED TEMPERATURE
IS A MINIMUM OF 150° C (302° F). IF LEAVING THE LAB
FOR AN EXTENDED PERIOD OF TIME, YOU MAY TURN
THE FURNACE OFF WITH THE TABLE IN THE CLOSED
POSITION. BEFORE FIRING PORCELAIN AGAIN, GO
THROUGH THIS DRY OUT PROCEDURE.
