PF 690 is a Red Stoneware clay ideal for potters seeking a high-fired clay body. Its fine texture makes it excellent for throwing large pieces and hand building, without the fear of slumping. This versatile clay can also be used as a Red Raku body. PF 690 is known for its outstanding plasticity and the right amount of tooth, which makes it resistant to warping, cracking, and thermal shock. When fired at 1100°C – 1180°C, it yields a beautiful brick red colour. Increasing the temperature to 1220°C-1260°C, the colour gradually darkens to a rich reddish-brown.

Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

UK company
Registered at Companies House as VALENTINE CLAYS LTD, number 04610423. Checked 2026-08-29.
Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.
UK operations
Not yet checked.
Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.
British-owned
No majority shareholding traced outside the UK. Companies House.
Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.
Where it is made
The maker doesn't say, so neither do we.
This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
