What You Will Learn

Are your pieces breaking or full of bubbles? Are your slumped pieces lopsided? Are published firing schedules not working for you? Do you rely on capricious “kiln gods and goddesses” for good outcomes in the kiln? In other words, do you wish you understood firing schedules better to advance your artistic vision?

In this masterclass, you will learn about significant glass properties such as heat conduction, thermal expansion, surface tension, and viscosity in clear and practical terms. You will also learn in detail about the three critical parts of the firing cycle: initial heating, firing to process temperatures, and annealing. Finally, the importance of making critical observations while fusing for full fuse, tack fuse, and slumping processes will be explained.

With this knowledge, you will be able to design and modify your own firing schedules and make critical decisions during firing such as when to end a slump and solve problems when they occur.

Take control of your firing schedules and advance your art to the next level!

This course requires a competent understanding of kiln programming and firing. Intermediate/Advanced experience is advised. 

Please note: This course was previously run as a seminar. Bob has developed the content into a Masterclass involving technical handouts and practical elements. If you attended the seminar then this course would contain content you have seen before.

PS: A more detailed explanation of firing schedules can be found in Bob’s e-book Firing Schedules for Kilnformed Glass: Just Another Day at the Office. Buy your copy from Warm Glass: https://warm-glass.co.uk/ebook-bob-leatherbarrow-firing-schedule-for-kilnformed-glass-p-5341.html

Session times

• Wednesday 3^rd August - 5.30 pm-7.00 pm UK time (1.5 hours)
• Wednesday 10th August - 5.30 pm-7.00 pm UK time (1.5 hours)

How it Works: 

• The course is made up of two live and interactive online sessions using the Zoom platform. You will find the zoom link via the week chapters in the navigation panel.
• Bob will give a step-by-step tutorial with demonstrations, and you will have ample opportunity to ask him questions during the live class
• Each week he will demonstrate a technique for you to try between sessions
• A member of the Warm Glass team will also be in the Zoom class to assist you and Bob
• Mix with Bob and other students on our dedicated community page, open for the duration of the course. Then join our exclusive Warm Glass UK Online Glass Community Facebook group to continue to mix with those who have attended any of our online masterclasses
• A materials list is provided in the course navigation panel, so you can purchase what you need to create your pieces during the course. You don’t need absolutely everything on this list to be successful, Bob will discuss different ways to reach our technical goals

We believe that this is the best way to get the very most from the course, but if this doesn’t suit you that’s fine: - If you can’t get to your studio, you can still learn the techniques and benefit from Bob's extensive knowledge without making the pieces during the course itself.

This is a live online masterclass, but in case a student experiences issues with internet connection during the live class, a recording of each live session will be available to view until two weeks after the final session. This cannot be downloaded or shared and is only available for this limited time. By participating you agree to be recorded for this purpose.

These recordings will be available in the course navigations panel. 

What to Prepare

• You will need a computer, tablet, or phone with a camera and microphone in order to join the online classroom. If you are unfamiliar with using Zoom then please take some time to look at our guide, available in the navigation panel. 
• You should have a reliable internet connection, fast enough to make video calls or stream videos
• Please read the Student Participation Agreement
• Ensure that you have checked the materials list and purchased any materials you may require 
• A pen and paper to take any notes. 
• We restrict the class size to 20 people
• We teach using Bullseye Glass (CoE90)
