Introduction to Crystals
About the event
Our day will be divided into four sessions. We will begin by looking at how people viewed crystals in classical times. During the 17th and 18th centuries a modern understanding began to emerge. Studies by Steno, Hooke and Hauy laid the foundations of the modern science. Development of the polarizing microscope in the early 19th century allowed the accurate identification of crystals in rocks. By the early 20th century X-ray techniques for crystal determination became available.
For the second session we will discover how atoms combine together to create the various crystal shapes that we see. You will have an opportunity to study their internal and external form including a practical investigation of a gypsum crystal.
After lunch we will look at crystal symmetry and explore the seven crystal systems. Then we shall explore how crystals grow and why sometimes the same mineral exhibits different crystal forms.
The last session will explain how crystals interact with light and how such interactions can be used to identify minerals in rocks.
There will be various practical sessions throughout the day.
Suitable for beginners and improvers.
