What is the course about?
This course tells you all you need to know to make work that is safe for the user. This covers glaze stability and food safety, pots for the kitchen, and all the other aspects of producing good, safe, functional work. For those who make their own glazes, it doesn't go into the glaze chemistry, which is now in a separate course.
Note that this course does not go into glaze chemistry in detail. If you make up your own glazes and want in-depth coverage of the chemistry, you may want to follow this course up with the Food Safe and Stable Glazes course (see bottom of page).
How is it Delivered?
The course is structured into six modules (nominally weekly but you can decide on your own pace). Each module consists of a video presentation, a PDF of the presentation for you to download, and links to additional material (both on and off my tech website) that you may wish to explore if you want more detailed information on any aspects of the course.
You're also encouraged to ask me questions about the course content and your practices during the course. This may be by email, or by participating in the monthly "Ask me Anything" video conferences for all my current students and Patreon supporters.
You have access to the course material for 10 weeks from your booking date. After that, you can have access whenever you want by supporting me on Patreon for the cost of buying me a cup of coffee each month.
What will we cover?
All aspects of product safety are covered, giving you the underlying theory, the means to test pieces, how to improve the design, and the relevant standards and legislation.
A considerable proportion of the course covers making durable glazes, crazing, leaching and food safety. Attention is also given to all the items that may be used on the table or in the kitchen. Also producing pieces that are frost proof. And general considerations such as stability and waterproofness.
What will I achieve?
By the end of this course you should be able to…
- Understand glaze stability and how to test it
- Understand glaze leaching in both alkaline (dishwasher) and acidic (food) environments
- Understand what is meant by "food safe", which materials in glazes are potentially toxic, and you can assess commercial glazes
- Understand the effects of thermal stresses on clay and glazes, and how to design to minimise them
- Understand the requirements to make pieces safe for the dishwasher, oven, microwave and freezer, and methods of testing their behaviour
- Understand the mechanisms of frost damage to pots, and the design and material considerations in making frost proof pieces
- Understand the level of waterproofness needed by different pieces, and how to test it
- Assess whether a piece is sufficiently stable for its purpose
- Understanding the issues in making electric lamps both safe and compliant with the regulations as easily as possible
- Design candlesticks and other pieces with an open flame
- Understand the legislation and standards covering product safety and testing (UK, EU and USA)
What level is the course and do I need any particular skills?
Intermediate.
How will I be taught, and will there be any work outside the class?
The course is primarily run through video lectures.
Additional material that you may wish to explore is on the course website. This will help you go deeper into the subject matter, should you wish to do so.
There will be suggestions for you to do tests on your pots in your studio between sessions.
For those with an imperfect knowledge of English, all session recordings now have subtitles in the languages of all attendees. This uses computer translation, so isn't guaranteed to be perfect, but should help you in following the sessions.
Are there any other costs? Is there anything I need to bring?
No advance preparation is needed.
You may want to test some of your work (which will probably get damaged in the process).
This mostly uses standard studio and kitchen equipment, though the following are useful if available:
- A pressure cooker
- Methylene blue or a similar dark stain (5ml is plenty)
- pH paper or a pH meter
- 50g of soda ash
- A digital probe thermometer reading from -20° to 250°C, e.g. a meat thermometer
What do I get?
- Six lectures , each lasting about 90 minutes
- Recordings of all lectures for later viewing during the course, with subtitles in all attendees' languages
- Additional optional online course material, giving background info and greater depth
- Optional participation in monthly "Ask me Anything" live online discussion sessions
- Downloadable PDFs of all presentations
- Premium level access to the Tech part of my web site, containing much more information, references etc.
- Course attendance certificate
Note that the lecture recordings and premium level site access are included at no cost until 10 weeks after you sign up to the course. After that, continued access is available for the cost of buying me a coffee each month.
Feedback from students
I found the course both informative and enjoyable. Tim has a wealth of knowledge and experience, and a natural ability to present a technical subject in a way that makes it accessible to non-specialist. Recommended!

I am happy to recommend Tim's online webinar on Product Safety as a great way to improve the quality of your pots. He covers all the aspects of making from design to clay bodies, glaze materials and firing schedules. Coming from an engineering and design background his approach is quite different to that of the average art college. Whether or not you have a scientific background, testing and experimenting will become a natural part of your designing and making. Ideal for potters producing functional pots ranging from domestic ware to garden pots, who aim to improve their product.

Great couse, I've learned a lot thanks to Tim. His course is technical, complete and simple. I do recommend it.

Thank you Tim for your course. Good structure of each lesson, well prepared, I like the way you explain. You did a huge work. You give all your knowledge on the subject but without unusefull controversy. I recommend if someones want to have a large point of vue on product safety. Sorry for my approximative english.
