The principle of operation is the same for both types. The furnace is normally supplied
programmed to operate between a pre-determined setpoint (start temperature) and
1500 °C at a ramp rate of 7 °C/ minute. The target temperature is set to 1500 °C to
avoid operating the furnace at high temperatures unnecessarily. See section 4.7.2.2.
The following text describes how to use the furnace with this program.
1. Open the furnace door to check that the silica window is clean. Any slight haze
should be removed before use. If neglected this haze quickly thickens and
becomes impossible to remove. See section 5.5 for instructions on how to remove
and clean the viewing window.
2. Turn on the 'oxidising', 'reducing' and 'purge' gas supplies. If the 'purge' gas is not
present when the furnace electrical supply and instrument switch are on the con-
trol system will activate an alarm buzzer and illuminate a warning light on the
