Description
Ramp and Hold Mode allows the operator to design their own firing programs. A Firing Program consists of 1 or more
segments strung in succession which give the kiln instructions on how to control the temperature. The GlassMaster controller
will store up to 6 custom designed programs in permanent memory.
Segment (SEG) consists of 3 pieces of information:
• Rate (RA)- The measurement of how fast or slow the temperature rises or falls at various points in the firing. This is
programmed in degrees Fahrenheit or Celsius per hour.
• Temperature (°F) - This can be the peak temperature of the firing program, a point in the firing program that signals the
rate to change, or that signals a hold or soaking period. This is entered in degrees Fahrenheit or Celsius.
• Hold (HLD) - “Hold” is a period of time in which the kiln remains at a specific temperature. This is often referred to as
a soaking period. This is entered in Hours and Minutes. The digits to the left of the decimal represent hours and the
digits to the right of the decimal represent minutes. Therefore 90 minutes can be represented by “01.30” or “00.90”.
A single program can consist of up to 8 segments. A segment can control the cooling as well as the heating of the
kiln. It is important to remember that a segment that controls the cooling of the kiln can only slow the natural cooling rate
of the kiln. It is possible to string two programs together to create a 16 segment program. See the 16 Segment Programs
section for instructions.
In order to ensure programming success, it is very important to have a good understanding of heating glass and
how your GlassMaster works to control the kiln. Please refer to the General Firing Guidelines section of the manual before
programing the kiln.
