We all know that annealing is essential to successful kilnforming of glass. How to write a successful annealing schedule is the question. We tend to use annealing schedules prepared by glass or kiln manufacturers. They cannot cover all the variations needed for different circumstances. They can only give a middle way.
There are many factors that affect how a piece needs to be annealed. Among them are the profile, the shape, the colour combinations, re-firing, high temperature work, castings, drops, cooling factors and many others. Annealing is also more than a soak at a particular temperature. It is the cooling to avoid excessive temporary stress, too.
It is difficult to write a new annealing schedule or evaluate one that is offered. Understanding the concepts and principles of annealing is important to producing soundly annealed pieces. But the concepts and principles relating to annealing do not appear to be well known.
This book describes the concepts involved in annealing, and the principles for making use of these concepts. It then combines them into a description of good annealing practices, explaining how to construct an effective annealing schedule for a variety of conditions. Now you can always be ready to craft annealing schedules for novel circumstances.
