Is cordierite a cyclosilicate?
Cordierite (mineralogy) or iolite (gemology) is a magnesium iron aluminium cyclosilicate.
What is cordierite used for?
Cordierite is a mineral with very few industrial uses. It can be used as an ingredient for making ceramic parts used in catalytic converters. However, synthetic cordierite is used instead because its supply is reliable and its properties are consistent.
Is cordierite man made?
Cordierite, discovered more than two centuries ago, is a naturally occurring mineral compound containing magnesium, iron, aluminum, and silicon. It’s found, among other places, near veins of tin in the mines of Southern England.
Is cordierite a ceramic?
Cordierite ceramic is a magnesium aluminum silicate material that has been widely used in applications where thermal shock resistance is important. Cordierite ceramic is also useful because it has a low thermal expansion and good electrical insulation compared to other ceramic materials.
Is iolite rare?
Is Iolite Rare? Iolite is quite popular and easily found. Finer pieces of iolite crystal can be tricky to find from time to time, but in general, these stones aren’t rare.
Is cordierite safe to cook with?
Since the cordierite stone is capable of withstanding temperatures up to 2,000 degrees Fahrenheit, you can safely use it in the oven, on the grill, and even under the broiler.
Does cordierite contain lead?
Whether it be cordierite, mullite or other types of refractory materials they all are fused at such high temps that they become, for all practical purposes, inert. Also their chemical composition contains no toxic metals such as lead.
How is cordierite Stone made?
The cordierite stone is made from a blend of lead-free clay, which retains and evenly distributes heat well, plus it features raised edges on the bottom to make it easier to lift out of the oven. This pizza stone is made by iconic French brand Emile Henry, producer of fine cookware and bakeware since 1850.
Is cordierite pizza stone safe?
What is cordierite made of?
Cordierite, discovered more than two centuries ago, is a naturally occurring mineral compound containing magnesium, iron, aluminum, and silicon. It’s found, among other places, near veins of tin in the mines of Southern England.
When was cordierite discovered?
Name and discovery. Cordierite, which was discovered in 1813, in specimens from Níjar, Almería (Spain) is named after the French geologist Louis Cordier (1777–1861).
What type of metamorphism is cordierite?
Occurrence. Cordierite typically occurs in contact or regional metamorphism of pelitic rocks. It is especially common in hornfels produced by contact metamorphism of pelitic rocks. Two common metamorphic mineral assemblages include sillimanite -cordierite- spinel and cordierite-spinel- plagioclase – orthopyroxene.
What is the color of transparent cordierite?
In its most typical habit, when a transparent Cordierite specimen is viewed through one angle, it will be violet-blue to blue, and when shifted it will turn gray or yellowish. Cordierite forms a solid solution series with the rare mineral Sekaninaite. Cordierite is the magnesium-rich end member, and Sekaninaite is the iron-rich end member.
