A day of talks and workshops to be held at the Natural History Museum in London (UK), in association with Geological Curators’ Group.

Booking has now closed - please stay tuned for more events


The day is aimed at all conservators and curators who work with geological collections, but there may be interest from other museum professionals, students and volunteers.

The morning session will comprise of presentations focussing on current research, recent projects and re-storage techniques. Workshops will be held in the afternoon. Workshop participants will learn how to identify pyrite oxidation, how to undertake dry cleaning techniques, how to create anoxic microenvironments and how to use humidity-controlled environments to slow oxidation rates. The afternoon workshops are aimed at colleagues who have not had the opportunity to specialise in natural history and are less familiar with pyrite oxidation. The morning session is unlimited but the afternoon session is limited to 20 people.

Geological Curators tackle pyrite oxidation!

Over fifty museum professionals from a variety of different backgrounds travelled to London for our recent seminar "Pyrite Oxidation: where are we now?", run in conjunction with the Natural History Museum. During the seminar, the causes of the problem were examined, along with current best practice for preventing the progress of decay. A full review of the day will be available here soon.

Our next event is "Making replicas of your specimens - a beginners course"
