The fact that obsidian IS glass. It is a naturally occurring form of volcanic glass. Different impurities give it different colors, usually black or shades of gray.
In Ghostscape 2, the obsidian blade can be found in the attic of the haunted house. Look for a hidden compartment near the window where you can retrieve the obsidian blade.
Obsidian (volcanic glass) is unstable and it de-vitrifies (crystallizes) with time, it is also only produced from viscous, acidic lavas. You would therefore look for it in recently produced lavas in continental volcanoes. Thus while obsidian is not uncommon, it does not last very long geologically. Where it is found it is found in large amounts.
Pumice normally doesn't have any grains at all. It would be very unusual for it to have grains. Just like Obsidian, Pumice is cooled too fast to have any grains in it. One of the biggest differences between them is that Pumice is cooled with pockets of air while Obsidian has a glassy look.
To determine which row in the chart best explains the movement of molecules between the model cell and the solution in the beaker, look for a row that describes processes such as diffusion or osmosis. These processes involve the movement of molecules from an area of higher concentration to an area of lower concentration across a semi-permeable membrane. Additionally, consider whether the row includes details about the direction of movement relative to concentration gradients. The best row will clearly illustrate these principles.
Green fluorite typically appears as translucent to transparent with a range of green hues, such as light mint green to deep emerald green. It often forms in cubic or octahedral crystals, with a glassy luster and can exhibit color zoning or banding.
Yes that is why it makes that glassy look to it.
because an obsidian rock has low silica
It sometimes has a blue glassy look to it!

i think obsidian is a supercooled liquid of a magma.Its look like a glassy matter because is crystallised very faster than basalt and granite. Granite cools very slowly that's why it shows coarser grains and it crystallizes at very depth whereas basalt crystallizes at surface that's why it shows medium grain size.
Obsidian is a beautiful rock. It's description is pretty simple, it is a rock that formed out of cooled lava, and is black in color.

A high-gloss finish typically imparts a glassy look to walls. This finish has a shiny and reflective surface that gives the appearance of glass. It is often used in areas that require easy cleaning, such as kitchens and bathrooms.
Cats' eyes may appear glassy due to a layer of reflective cells called tapetum lucidum behind their retinas, which helps them see better in low light.
Different people look at future risks differently
Glassy eyes in cats can be a sign of various health issues, such as eye infections, dehydration, or even more serious conditions like diabetes or kidney disease. It is important to consult a veterinarian for a proper diagnosis and treatment.
