About This Event

A free workshop on traditional compo making and moulding is held at Osterley Park and House in London. The session focuses on the craft used to restore mirrors as part of the Breakfast Room conservation project.

Step behind the scenes of our Breakfast Room conservation project and discover the fascinating craft helping to restore Osterley's magnificent mirrors.

As specialist conservators carefully repair the historic mirror frames, they are recreating missing decorative details using a traditional ornamental material called composite, or "compo", a mouldable material widely used from the 18th century onwards. You can even watch the conservation work in action every Wednesday and Thursday in the House.

Now it's your chance to have a go yourself. In this hands-on workshop, you'll learn how compo is made, using a traditional English recipe, before moulding your own decorative ornament to take home.

As a craft now recognised on the Red List of Endangered Crafts, this is a rare opportunity to experience a traditional skill that is helping to preserve some of Osterley’s historic collection.

Thursday 30th July & 6th August

Adults (18+) only

Limited to 8 places per workshop
