What is the difference between gypsum crystals and glass in terms of atomic structure?
-Gypsum crystals have atoms deployed in a perfect order, similar to soldiers in a rigid formation, while glass has atoms disposed without any pattern, akin to a dispersed army, resulting in different properties and uses for each material.
What is the origin of the word 'crystal' and its association with supercooled water?
-The ancient Greeks called transparent stones 'cryos,' believing they were supercooled water, which ultimately gives origin to the word 'crystal,' reflecting their perception of the material's transparency and beauty.
What is the composition of gypsum crystals?
-Gypsum crystals are composed of calcium sulfate molecules stacked in layers, alternating with layers of water molecules.
How were the giant gypsum crystals of Soria extracted and transported?
-After extraction, the valuable gypsum crystals were transported by caravans from Soria to the ports of Sagunto or Cago Nova, and then shipped to the Roman metropolis and other parts of the Empire.
What is the significance of the Cave of the Giants of Naica in Mexico?
-The Cave of the Giants of Naica is significant because it contains some of the largest gypsum crystals in the world, formed over millions of years due to the slow cooling process of the Naica mountain range and the dissolution of anhydrite.
What challenges did the researchers face in studying the Cave of the Giants of Naica?
-The researchers faced challenges such as extreme heat and humidity, the need to preserve the crystals and cave environment, and the difficulty of extracting and studying fluid inclusions within the crystals to determine their formation conditions and age.
What is the estimated growth rate of the gypsum crystals in the Cave of the Giants of Naica?
-The estimated growth rate of the gypsum crystals in the Cave of the Giants of Naica is about 60 microns per century, making it the slowest growth velocity ever measured in a mineral process.

Highlights
The prosperity of the ancient Roman city of Soria revolved around mining and the mineral selenite, which was highly prized in Rome.
Selenite, or lapis specularis, is pure gypsum in crystallized form and was found exclusively in the area around Soria, Spain.
The Roman historian Pliny the Elder documented the unique properties of selenite in his Natural History encyclopedia.
Giant gypsum crystals, some reaching up to 7 feet long, were extracted from the mines of Soria.
The Romans utilized the remarkable property of cleavage in these crystals to obtain thin sheets used in construction and for other purposes.
The advent of flat glass production in the Roman Empire led to the decline of Soria, as the new material was cheaper, despite not being as transparent or ornate as gypsum.
The difference between crystal and glass lies in the order of their atomic structure; crystals have a rigid, ordered formation, whereas glass has a disordered atomic arrangement.
The geode of Pulpi, discovered 500 km south of Soria, contains enormous gypsum crystals of near-perfect transparency.
The Cave of the Swords in the Mexican desert of Chihuahua is famous for its spectacular gypsum crystals, some over 1 foot long.
The giant gypsum crystals of the Cave of the Giants in Naica, Mexico, grew slowly over half a million years due to the dissolution of anhydrite and continuous feeding of calcium sulfate-rich waters.
The preservation of these unique crystal caves is crucial, as they represent priceless treasures of the mineral world and cannot be replicated.
The crystal caves of Naica are considered the Sistine Chapel of crystallography, showcasing the largest and most impressive mineral formations on Earth.
The growth rate of gypsum crystals in the Naica mine is exceptionally slow, at approximately 60 microns per century, making them half a million years old.
The discovery of the giant gypsum crystals in Naica, Mexico, has challenged crystallographers to understand the conditions and processes that led to their formation.
The future preservation of the crystal caves in Naica depends on decisions made when the mining operations cease, balancing the potential for a natural museum with the extraction of the crystals.
The crystals of Soria, Pulpi, El Tente, and Naica are unique phenomena that require preservation, akin to historical monuments like the Mayan pyramids or the Grand Canyon.
