E-Book / Workbook - Firing Schedules for Kilnformed Glass

Bob Leatherbarrow E-Book / Workbook

Skill Level: Beginner




 Just Another Day at the Office

 by Bob Leatherbarrow

 This comprehensive guide introduces a new approach to designing and understanding firing schedules by breaking the firing cycle into three stages, each of which has unique challenges and is independent of the other two.The three stages are: initial heating through the brittle zone; heating to process temperature within the ductile zone; and annealing, and cooling back to room temperature through the brittle zone. Using this logical approach you will not only get improved results and reduce glass breakage, but you will also be able to develop and/or revise schedules to fit your specific needs.

 This book helps you develop an understanding of:

  • The physical and chemical properties of glass
  • How glass behaves when heated in a kiln, and
  • The critical observations to be made at each stage of the firing cycle
  • How to design component firing schedules and combine them into overall schedules



  • 219 fact-filled pages written in an easy-to-understand style
  • 109  figures and illustrations explaining the properties of glass and demonstrating proper use of kilns
  • Just Another Day at the Office analogy that is the foundation for this innovative approach to developing firing schedules
  • 14 component firing schedules (in ºC and ºF) for initial heating, full fuse, tack fuse, slumping, and annealing that can be combined into overall schedules for individual projects
  • Specific component firing schedules for challenging projects, such as slumping with drop-out and deep-form moulds
  • Practical solutions for reducing or eliminating air bubbles, managing devitrification, and including chemical reactions as a design feature
  • Approaches for using options available on many controllers for better project outcomes
  • Based on 30 years of experience in kilnformed glass and a background in science

  1. Excellent resource review by Mary on 10/22/2018

    This is a book I will be referring to for a very long time. Learning to use a kiln has a high learning curve starting out in glass, and I had been searching for a reliable source of information. This is it! Extremely helpful in learning about how glass heats and cools, what schedules to use and how to adjust them. The author is very knowledgeable and explains the topic in easy to understand terms. Just what I needed to master kiln formed glass.

  2. The book everyone who fusing glass needs to read review by Tim on 10/17/2018

    Amazing book. Well organized and he has an exceptional take and view of fusing schedules. You wil understand the reason for the different steps in a fusing schedule.

  3. What a Fantastic Reference! review by KRISTIN Quarton on 9/29/2018

    I have found myself using this more than I anticipated. I am so glad to have it hand when I doubt a schedule. I can go in and find something similar at my fingertips. I have learned so much from him through all that he shares. A truly wonderful addition to my collection.

  4. Excellent review by Caren on 9/19/2018

    Answered so many questions. A must have

  5. FINALLY...the WHY! review by Judy on 7/1/2018

    I’ve always wanted t know the “why” not just to “what” and “how”. I was unable to wrap my head around why there were so many firing schedules for what, I thought, was the same process, I.e., a slump was a slump was a slump. NOW I SEE WHY! Leatherbarrow has shared his years of craftsmanship and experience with us. Sometimes it gets quite technical, but what happens to glass when it’s heated IS quite technical! I’ve read parts of this book several times and. noted other parts to refer back to when I plan a new piece. Thank you so much for the time and effort you put into this book, but, most of all, thanks for sharing your knowledge!
