What cordierite?
cordierite, also called dichroite or iolite, blue silicate mineral that occurs as crystals or grains in igneous rocks. It typically occurs in thermally altered clay-rich sediments surrounding igneous intrusions and in schists and paragneisses.
How is cordierite made?
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 cordierite stone made of?
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.
Is cordierite the same as iolite?
“Cordierite” is a name used by geologists. When the mineral is transparent and of gem quality, it is known as “iolite” in the gem and jewelry trade. Two older names for the mineral are “dichroite” and “water sapphire.” The name dichroite means “two-color rock,” inspired by cordierite’s pleochroic property.
How hot can cordierite get?
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.
Is cordierite safe for food?
This feature helps ensure breads, pizzas, and other baked goods cook evenly throughout. 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.
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.
What is the specific gravity of cordierite?
Calculated Properties of Cordierite : Electron Density: Bulk Density (Electron Density)=2.63 gm/cc note: Specific Gravity of Cordierite =2.65 gm/cc. Fermion Index: Fermion Index = 0.01 Boson Index = 0.99 : Photoelectric:
Is synthetic cordierite shock resistant?
This synthetic cordierite could be rapidly heated and cooled, while barely changing dimensions, making it very thermal shock resistant.
Why Corning cordierite?
For more than four decades, Corning has continued its research and development on cordierite, improving the material in new and innovative ways to meet the demands of today’s automakers for substrates with thinner walls and more channels per area, to further reduce emissions, with minimal impact on fuel economy.
