- Setting Space The setting dimensions used on this site are net dimensions.
That is, they represent the actual, useful dimensions that can be set within.
The numbers do not represent wall to wall dimensions, or dimensions that include flue space or free space.
- Firing Cycle The firing cycle is the time from lighting the burners until the kiln is opened.
This is often referred to as 'cold-to-cold' firing time and includes cooling time.
- Burn Same as firing cycle
- Consultant or Consulting A consultant is one who has spent considerable time and effort learning about
some specific area of expertise. They are then willing to pass that important information along to others
so that they do not have to suffer the trials and tribulations that they went through.
- Over Temperature Control This is a separate control with a separate thermocouple set into the hottest part of the kiln.
If anything should happen to the the automatic controls, or if the kiln is being controlled manually
and the temperature rises too high, this control will cut off the fuel or electricity heating the kiln.
The set point of an over temperature control should be about 25 degrees F above the the temperature at this point
when the kiln is at peak temperature.
the control will then protect both the ware and the kiln.
- Drying finish points,
- Leather Hard The ceramic is dried to the point where shrinkage has stopped, but is still pliable, like leather.
This is a good working point for cleaning or shaping since it handles well.
- White Dry, or Finish Dry This is a point where the ceramic appears dry and is another useful point to apply finishing techniques.
- Bone Dry This is the point at which there is no more moisture in the ceramic. It is complete and ready for firing.
- CFH Cubic Feet Per Hour, a measure of the volume of air or gas flowing per hour. At sea level 1,000 CFH = 1,000,000 BTU per Hour.
- BTU British Thermal Units is a measure of heat. 1 BTU is the amount of heat required to raise one pound of water one degree .
Burners are rated in BTU to specify the amount of heat that they release per hour, kilns are rated in BTU to show the total amount of heat per hour that
they are capable of. For example, a 1,000,000 BTU kiln will have twice the heating power of a 500,000 BTU kiln and, thus,
would be capable of heating the same load much faster.
- Joule A measure of heat similar to BTU. 4186 Joules = 1,000 calories; 1BTU = 252.0 calories or = 1055 Joules.
- Production Potters Other than a different mind set a Production Potter is Industrial; their goals and aims are the same.
In some cases a production Potter may even be larger than an other company referred to as Industrial.
