What igneous rock has crystals that are not visible?
Extrusive igneous rock consists of mineral crystals that are not observable with the naked eye. Obsidian is an extrusive igneous rock (volcanic glass) where there technically are no mineral crystals.
What is an igneous rock that cooled very quickly called?
An igneous rock that cooled very quickly is called a volcanic glass, such as obsidian. These rocks lack a crystalline structure due to rapid cooling, resulting in a more glass-like texture. Their composition is similar to that of other igneous rocks but with a characteristic lack of defined mineral grains.
Colourless or brownish material used in glassmaking?
Glass batch or cullet is the colourless or brownish material used in glassmaking to produce glass. It is a mixture of raw materials such as silica sand, soda ash, limestone, and recycled glass that is melted in a furnace to create glass products.
Which material is mostly made of the mineral quartz?
Granite is a material that is mostly made of the mineral quartz. It is a common type of igneous rock that contains high amounts of quartz along with other minerals such as feldspar and mica.
What mineral is harder than calcite but wont scratch glass?
Fluorite is a mineral that is harder than calcite but won't scratch glass. Calcite has a hardness of 3 on the Mohs scale, while fluorite has a hardness of 4. However, glass typically has a hardness of about 5.5, making it too hard for fluorite to scratch.
Extremely rapid cooling lavA in which no crystals form?
the reterded mineral
What mineral is in laundry detergent and making glass?
phosphate
Is volcanic glass a mineral group?
No, volcanic glass is not a mineral group. It is a type of igneous rock formed from the rapid cooling of lava without the time for crystallization to occur, resulting in an amorphous (non-crystalline) structure.
What mineral is used in making glass and laundry detergents?
phosphate
What is the igneous rock that cooled too quickly for a crystal structure to form?
Volcanic glass or obsidian is a quickly cooled igneous rock without a mineral crystal structure.

Why do recycled glass countertops cost cheaper than mineral glass countertops?
I would think that the answer is simple and resides in the simple business economic laws of supply and demand. The supply of glass for recycling is abundant whereby the material for making mineral glass countertops must be brought in and processed before making it into a countertop.

Glassy igneous rocks form when magma cools too fast for mineral grains to grow?
Yes, that's right. Glassy igneous rocks, like obsidian, form when lava cools rapidly, preventing the formation of crystals. This rapid cooling inhibits mineral crystal growth, resulting in an amorphous, glass-like texture.
When a glass rod is immersed in the colourless liquid the glass rod seems to be deappeared why?
Hey! The reason it seems to disappear is because of the refraction and absorption of light and colour. When light enters the colourless liquid, colour is obviously absorbed. The light waves refract ("bounce") off the glass test tube and leave the glass beaker (containing the colourless liquid). Because the liquid and solid are the same colour, it creates the illusion of the test tube disappearing.
