FLASK BURNOUT USING THE KILN
20
Once the investment is completely dry, place the flask(s) inside the Fuser500™ kiln. Position
flask(s) with the dug hole facing up or sideways. Never position the hole facing down. Close
the lid and turn on the kiln.
Your kiln’s lid will not fully close due to ventilation purposes.
EXPERT TIP:
Do not let the flasks touch the front and back walls of the Fuser500™ kiln where the
heating elements are located. Failure to do so may cause flaws and porosities to the investment.
Both sidewalls may be used as a support system to fit more than one flask.
Burnout time varies between 3
½
and 4 hours
and only draws less than 4 amps when operating.
Do not leave the flask(s) past 3
½
up to 4 hours; otherwise, they may overburn and cause flaws
and porosities to the investment.
During this process, the interior of the kiln and investment will turn black. When the wax calcines,
everything will return to its regular color, and the investment cavity will be glowing red. This is
when you should prepare to pour in the metal.
WARNING:
Do not open the kiln during the burnout process. Do not touch the interior of
the kiln. Do not use the kiln for any other purpose. Use caution and common sense when
operating the Fuser500™ kiln. Misuse may result in product damage and severe injury.
