# Plymouth & Bristol Porcelain > A photographic catalogue of an 18th-century Plymouth and Bristol porcelain > collection, with cross-tabulated analysis of decorators, marks, and services. This site documents pieces produced by England's earliest hard-paste porcelain factories, founded by William Cookworthy in Plymouth in 1768 and continued in Bristol under Richard Champion until 1781. Each piece is photographed and catalogued with its type, service, decorator, factory mark, size, condition, historic provenance, and notes. The catalogue is cross-tabulated so that relationships between decorators (numbered painters working at the factory), mark groups (tin, X, B, cross-and-dot, etc.), and named services (such as the Smith service, Plumer service, Cookworthy service) can be explored. The full catalogue, including descriptive metadata for every piece, is available in markdown at /llms-full.txt — this is the recommended source for question answering about specific pieces, decorators, marks, or services. ## Pages - [Home](https://bristolporcelain.com/): Introduction to the collection. - [Catalogue](https://bristolporcelain.com/catalog): Browse and search every catalogued piece, filterable by type, service, mark group, and decorator. - [Services](https://bristolporcelain.com/services): Documented services (e.g. the Smith, Plumer, Cookworthy services) within the collection. - [Analysis](https://bristolporcelain.com/analysis): Cross-tabulated analysis of decorators, marks, and services. - [Compare](https://bristolporcelain.com/compare): Load up to nine pieces side-by-side for visual comparison. - [References](https://bristolporcelain.com/references): Bibliography of papers, books, articles, catalogues, and museum collections. - [Contact](https://bristolporcelain.com/contact): Get in touch about the collection. ## Data - [Full catalogue (markdown)](https://bristolporcelain.com/llms-full.txt): One markdown block per piece, group and service with all catalogued metadata. - [Sitemap](https://bristolporcelain.com/sitemap.xml): XML sitemap listing every page including individual pieces. ## Optional - [Example piece](https://bristolporcelain.com/piece/H1l): A representative catalogue entry. - [Example group](https://bristolporcelain.com/group/G1): A representative group of related pieces.
