Thanks for coming to the technical part of my web site.
Researching and writing up all of the information on this site takes a significant amount of effort. Please consider becoming a supporter to help enable this site to grow in content. The more supporters I have, the more time I can spend expanding the site's content.
If you like what you find, and want to support further development of this site as a resource for potters, then please become a Supporter. This gives you access to the whole site, plus the ability to like or add comments to pages, suggest topics of interest to you, and participate in forums - and no screens asking for your support. The suggested subscription price is just US$3 a month, about the price of a cup of coffee, and your support will enable me to extend the content of the site for all.
This provides content that is primarily of interest to fellow potters.
As the content is all work in progress, whilst some pages are essentially complete, some may be incomplete or have sections with just draft notes, and some may not yet be written up.
Quick summaries on health and safety topics, as posted on Instagram and Facebook every Friday.
These are available to both registered and unregistered users.
This deals with all of the issues regarding health and safety in the studio.
A significant proportion of the content is given over to the toxicity or otherwise of materials used in the studio, as there is a lot of misleading information here. Hazards of kilns and kiln firing are covered, clothes and protective equipment; and avoiding muscular and other damage to your body.
It doesn't cover any of the issues associated with having other people in your studio, whether staff or people you are teaching. Whilst the same health and safety issues apply, there are often additional regulatory and administrative issues that may need addressing in these circumstances.
This covers producing products that are safe for your customer.
Food safety is a major topic, looking at leaching from clays and glazes, what levels may be toxic, and how it can be minimised. Other issues for tableware include making pieces suitable for ovens, microwaves and dishwashers; crazing; and cutlery marking.
For outdoor pieces, it covers issues such as making glazes weatherproof, and making pieces frost resistant.
General issues such as ensuring pieces are strong and stable are also covered.
Over the past few years I've been doing an increasing amount of wood firing, primarily at the Oxford University kilns. I've found it very hard to obtain technical information on kilns, the firing process, and the reactions involved - much of this seems to be transferred by word of mouth, and with a less technical and analytical approach than I tend to take. This documents my learning of wood fired techniques.
These are my research notes for a project for an exhibition at Chapel Arts Centre, Andover, for which I'm making two pieces about the Royal Flying Corps and World War 1. The first casualty of the RFC died nearby, and came from Andover, where he is buried.
