Fire for Your Kiln and Objectives

Often temperatures to achieve given effects
are shared on the internet to be helpful to others.
Those who receive these need to evaluate the schedules used to achieve
the profile at the stated temperature.
The same effect can be achieved at different temperatures by
using different rates and times in getting to the given temperature. This is summarised as the effect of heatwork. The longer taken to achieve the top temperature, the lower
the temperature can be used. The amount
of time the holds/soaks occupy in the schedule will also affect the profile
achieved. This means that a simple top
temperature can only be a point from which to begin exploration.
It is important to evaluate each segment. What is the apparent purpose? How does it fit with the principles of applying heat and the characteristics of glass?
When asking for help with a firing temperature, ask for the
full schedule. This will help you
evaluate the suitability of the temperature given.
The variations in schedules and kilns mean you should fire
by results not by numbers. Use the rates, temperatures and soaks that will
achieve what you want in your kiln.
