Heat & Time - Together the combinatin of time and temperature are called Heat Work. The amount of heat work at every stage of the firing schedule must be considered in order to obtain consistant results.

All of the varied kilnforming styles have a set amount of heat work to produce the effect. The amount of heat work not only varies by the schedule itself, but also by the size and type of kiln and what is inside of the kiln. The amount of heat work also varies by the glass type and color itself. A dark piece of glass will typically need less heat work than a lighter one since dark glass absorbs more heat. More important is the type of glass. The chemical makeup of the glass is a significant factor in how much heat work must be applied.

The three types of projects below have significantly different firing schedules due to the refined project objectives. Becuase to the many factors that make up heat work, a firing schedule that works for your kiln setup and your project goals must be 'discovered' and fine tuned over several attempts. Only fairly simple projects use generic firing schedules.
