Fluorite properties and lore


Fluorite properties

Fluorite is a calcium crystal which forms in bands, often of multiple colours. The colours are mostly greens and purples but also pink, yellow and blue. The rarest being the pink. However, it can also change colour in different types of light.

Fluorite typically glows a blue-violet colour under ultraviolet light some glow a cream or white colour whilst others do  not fluoresce at all. Fluorescence in fluorite is thought to be caused when trace amounts of yttrium, europium, samarium, or other elements substitute for calcium in the fluorite mineral structure.

When  sold in bulk Fluorite is called Fluorspar, and sold in three different grades (acid, ceramic, and metallurgical). Whilst having a wide range of different colours some has its own very unusual property:

Antozonite: Fluorite with the element fluorine incorporated in it. Known for its unpleasant smell when it is crushed because fluorine reacts to oxygen and water vapour to produce ozone.
Blue John: Only found in one small part of the UK. The mineral has bands of blue, purple, and yellow colours.

Chlorophane: This rare mineral has the property of thermoluminescence, meaning that it emits visible light when heated even from the heat of someone’s hand while they hold it.

Fluorite historical use and lore

The Chinese used the scarlet fluorite as a protection against bad spirits. Green fluorite would be a substitute for jade in stone sculptures.

The Egyptians would use fluorite to carve pearls, scarabs and other religious artefacts.

The Romans believed drinking alcohol in a carved glass of fluorite would avoid drunkenness. Objects made of fluorine were found in the ruins of Pompeii.

Drinking cups made from Murrine (almost certainly fluorite and mined in Persia.). The stone gave a strange, pleasing taste to wine when drunk from them. This taste was from residual resin (myrrh) that was applied to the stones, during carving to prevent shattering.

The Roman Historian Pliny the Elder wrote that ‘vasa murrina’ were first introduced to Rome by Pompey the Great in 62-1 BCE, after his victories in the East. The vessels were so desired that Pliny tells us that the highest price paid for a fluorspar cup was 1,000,000 sesterces, by the Emperor Nero. We also hear of a former Roman consul who paid 70,000 sesterces for one. He was said to be so fond of his cup that he gnawed its rim. The British museum have two very famous Roman drinking cups (the Barber cup and the Crawford cup) both made from fluorite.

The Romans excavated the famous “Blue John”, which is a peculiar blue yellow fluorite. The Latin word ‘murra’ is regularly identified with the mineral fluorspar.

In the Middle-Ages, Fluorite was called “ore flower.”

Murrino glass

Murrine (murrina) and Murrino glass has very ancient origins, the first works date back to 3,000-2,000 BCE by Syrian, Egyptian and Roman glassmakers. The term “Murrino” was used to identify all the mosaic glass vases and bowls that the Romans made using cane sections coloured patterns or images made in a glass cane. These are revealed when the cane is cut into thin cross designs such as faces, flowers and animals. These vases were made of murrha, a material characterised by the presence of Fluorite which gives the objects a particular smell, due to the resins used as a binder during the process or more likely because they were used to contain perfumes.

During the Middle Ages, the murrino glass technique was lost, but was restored at the end of the 19th century
