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.
Is tuff a mineral?
No. Tuff is an igneous rock. it contains a number of minerals as well as volcanic ash and pumice, which are forms of volcaninc glass.
Which mineral is made mostly of the mineral quartz?
window glass
What kind of igneous rock is obsidian?
Obsidian is an igneous rock. However it differs from other rocks because it contains no minerals. It consists of natural glass, which is not a mineral because it has no crystal structure.Answers from McDougal Littell, Earth Science book
Will mineral spirits damage glass?
No.

Extremely rapid cooling lavA in which no crystals form?
the reterded mineral
What mineral is in laundry detergent and making glass?
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.
What mineral is used in making glass and laundry detergents?
phosphate
What mineral is used for making laundry detergents and glass?
boron (borax)
Is tuff a mineral?

What type igneous is pumice intrusive small crystal or extrusive large crystal?
It is neither. Pumice is an extrusive highly vesicular igneous rock composed of volcanic glass and very tiny mineral crystals.
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.
What is an extrusive igneous rock that is actually glass?
One type of glassy igneous rock is obsidian, which is black and glass-like. Any type of igneous rock that is glassy would be a extrusive rock, which means it was formed outside the earths crust and cooled quickly, making for a fine grain and small crystals. hope this helps
What mineral forms glass?
The mineral quartz is the main ingredient in manufactured glass.
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.
