Fiona Hulbert

After years of dabbling via courses I retired from work and during Covid time set up my own little studio at home. When I was offered an old kiln I said yes with alacrity ….but having never had anything to do with the firing of my pieces then felt rather overwhelmed by the process of getting to know how to use it with the glazes I had. It is a whole new area of potting to learn to navigate. I was relieved to find Tim’s course online. It was the first affordable and easilyaccessible one I had come across. I… Read more “Electric Kilns and Firing Online Course – Review”

For anyone seriously going into ceramics and buying a kiln or taking on a studio with a kiln Tim’s course is packed with just about everything you need to know from buying a kiln and installation to maintenance, problems and faults and much much more. He’s very knowledgeable and amenable to answering your questions too. However this course is quite technical for the hobbyist potter and may be too detailed at this stage in your journey.

Fran Osborne

As soon as I found this course two other potters from the studio I go to signed up and it created a lot of discussion and interest with the other members. I would highly recommend anyone with a kiln or thinking of getting a kiln to do it. Tim is incredibly knowledgeable and very helpful from the most basic to the highest technical questions.

Course Details

This online electric kiln firing course teaches you how electric kilns work, how to fire them correctly, and how to carry out maintenance and troubleshooting. Understand how electric kilns work, how to get the best out of firing them, and how to look after them. This course provides you with all you need to know about owning and operating an electric kiln, starting from the basics. The electric kilns and firing course is one of my most popular courses, and has had hundreds of students since it was launched in 2022.

I have been making ceramics since 2008, starting with evening classes and then setting up my own studio a couple of years later. Over the years I have owned, fired, maintained, repaired and rebuilt a variety of electric kilns. With my background in science and engineering, I am drawn to the technical aspects of the craft, but enjoy explaining the technicalities in plain language to those with less technical knowledge. I regularly post on these lines on social media, and have been teaching since 2020, mostly online. The electric kilns and firing course is one of my most popular, and has had hundreds of students since it was launched in 2022.

By the end of the course you will have learned the following:

Kiln knowledge

  • Identify and understand kiln components and the digital controller
  • Understand how kilns heat up, and how they behave
  • Grasp the principles of temperature and heat work, and how we measure heat with thermocouples and cones
  • Understand how clays and glazes are transformed during firing
  • Learn the differences between bisque and glaze firing behaviour

Firing Operations

  • Load your kiln efficiently, and choose the most suitable kiln furniture
  • Develop reliable bisque and glaze firing schedules for your work
  • Program and use your kiln controller
  • Evaluate witness cones and firing logs, and interpret your firing results
  • Identify and troubleshoot firing faults in your clays and glazes

Kiln Selection, Installation, Maintenance and Safety

  • Know what to look for when buying a new or second‑hand kiln
  • Know how to install your kiln safely
  • Understand safety requirements (heat, electricity, fumes and ventilation)
  • Maintain your kiln, carry out routine checks, fault finding and repairs

Why do this electric kiln firing course, as opposed to just reading the kiln manual, or watching YouTube videos? I’d suggest that there are four key benefits:

  • I cover both the practicalities and the underlying theory. You’ll learn what you should do and why
  • Whilst the videos cover the key aspects of firing and maintaining a kiln, the additional material goes much wider, so you can explore the aspects that are of most interest/relevance to you and your practice
  • Kiln manuals just tell you where things are on your kiln and how to change settings. They don’t tell you what those settings should be, and why
  • I offer personal support for any questions you may have, not just about the course content but about anything ceramics related
  • Over 12 hours of video talks, divided into 8 modules, with subtitles in your language
  • PDFs of all presentations
  • Additional course material to help you go into topics in more depth, or broaden out to topics not included in the talks
  • Personal support through emailing in questions or joining the monthly Ask me Anything online session
  • Access to my tech website, which covers all of my course topics and more
  • Course attendance certificate
  • 12 weeks from your enrolment date to complete the course

A self-directed online study with access to your instructor:

  • You can start as soon as your order has been processed
  • Eight on-demand modules that you can take at your own pace

  • Do I need to own a kiln? No. You’ll still learn valuable theory, programming, and troubleshooting to apply in a studio setting. But there are a number of suggested exercises that you will find useful if you have access to a kiln
  • Will you answer questions on specific problems I’m having, even if outside of the course content? Yes, definitely. As well as helping you, answering questions makes running the courses more interesting for me, and sometimes suggestions changes to make to the course. So feel free to ask me anything.
  • Which controllers/kiln brands are covered? The videos cover things generically, as there are too many kilns out there to cover them all. Specific kilns and controllers are covered through the additional material, and through the emails and AMA sessions. If your kiln or controller isn’t covered, I’ll happily track down the necessary information for you, and take you through it.
  • Do you cover kiln sitters and manual controls? No, only digital controllers are covered, though most of the rest of the course is applicable to kilns with these older technologies.
  • How much time is needed? As a minimum, 13 hours to watch the 8 videos, but if you want to get the most out of the course you may find that you spend double this time on it.
  • Do I have lifetime access to the course? You have 12 weeks to complete the course. Then, at any stage after that, you can regain access by supporting me on Patreon for about the cost of buying me a coffee every month.
  • Do you cover glaze defects? Yes – module 6 covers diagnosing and fixing clay and glaze defects, and there is also more information in the additional material. If you have a specific problem, please ask me about it.
  • How technical is the course? Do I need advanced maths? This is a technical subject, but the technicalities are explained in plain language for those with minimal prior knowledge. Whilst some information is given mathematically for those who have the necessarily skills, it is also explained in a non-mathematical way for everyone else.
  • Are there any other costs? No, other than the cost of firing your kiln if you do any of the exercises
  • Is the course suited to those outside of the UK? Yes. The principles of kilns and firing them are universal. Whilst I mostly talk about European and North American kilns, I have some knowledge of kilns from elsewhere. For those in the USA, units are given in Imperial as well as metric units. The videos can have subtitles added for most languages, though the website and PDFs are in English.
