Outcrops to Paintbox, mineral pigments in artists paints.
Soft, coloured minerals which leave a strong streak have been employed as pigments for the last 500 thousand years. This talk will introduce some of the main minerals used as pigments, their chemistry and properties and discuss how they have been used in paintings throughout art history.

Portinscale Village Hall
by Christine Arkwright
The Lake District is rich in natural resources, particularly minerals, which have been exploited over many years.
These include primary or rock-forming minerals which crystallise directly from molten magma and secondary minerals, formed by hydrothermal, igneous and metamorphic processes.
This workshop will include a visual presentation about how minerals are formed followed by practical exercises to identify mineral samples from their different physical properties. There will also be a display of rocks and mineral specimens to browse and a polarising microscope to view rock thin sections.
Bring your own hand lens and grain-size card, if you have them, but spares will be available.
If you plan to attend please contact email hidden; JavaScript is required to book a place.
The Snowball Earth Theory of Global Glaciation
Date: 20th December
Time: 13:00
Speaker: Michael Hambrey, Emeritus Professor of Glaciology, Aberystwyth
Mike Hambrey, one of our members is giving a talk on Snowball Earth to the Intellectual Property Office in Newport, South Wales, and they are happy to invite other groups along. If any members are interested, they may like to follow the link below and register with Microsoft Teams. They will then get reminders nearer the time.
The talk is designed for people with a general science background, rather than geologists, but he will be focussing on the geological fieldwork he has done in Svalbard, East Greenland and Scotland.
