Dihl and Guérhard porcelain

Dihl and Guérhard porcelain (various variant names) was made by the Duc d'Angoulême's porcelain factory, a hard-paste porcelain factory in Paris, active from February 25, 1781, until 1828. It was founded by Christophe Dihl (1752-1830) and Antoine Guérhard (d.1793), together with Louise-Françoise-Madeleine Croizé (1751-1831), then married to Guérhard, but married to Dihl from 1797. Dihl was a chemist, and the factory experimented with new colours and finishes.
