Potterycrafts Harry Stringer Green Powder Decorating Slip

Potterycrafts

£11.07

Harry Stringer green decorating slip has been designed by Harry Horlock-Stringer of the Taggs Yard School of Ceramics to create effects similar to those that would be obtained from a flame fired reduction firing. Different thickness of slip and glaze, as well as a variation in firing temperature can produce remarkable effects in finished ware, such as obtaining blue, black, green and orange from the same slip application. Temperature Range: 1260-1280°C

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 POTTERYCRAFTS LIMITED, number 02354827. 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
Stated by the company: "our new pottery showroom at our head office in Stoke-on-Trent open to the public" Source.
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.
Foreign-owned
Majority ownership sits in France, with Harry Developpement Sas. 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.
