ES 170 (Glacier Porcelain)

Valentine Clays Ltd

£5.48

ES 170 Earthstone Glacier Porcelain, is a premier porcelain clay that combines exceptional whiteness, glass-like translucency, and remarkable strength. These qualities make it an ideal choice for potters seeking both aesthetic and functional excellence in their porcelain work. Unlike traditional porcelain, which often sacrifices plasticity for purity, ES 170 maintains both. This is achieved by using high-quality, low iron-bearing China clays, silicas, bentonites, and mineral fluxes, resulting in a porcelain that is brilliantly white, translucent, and highly workable.

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.
