You need a diamond pickaxe to mine obsidian :p
I can give you several sentences.The snow flake melted instantly.I found a flake of obsidian on the ground.That rock will flake easily when struck.You could also use the slang meaning of someone who is eccentric or odd. "That fellow is a real flake!"
The paint began to flake off.In Britain, Flake is a kind of chocolate bar.She choked on a chocolate flake in her mocha.
Obsidian has a higher luster(shinier) than coal, coal is organic, and coal is sedimentary and obsidian is igneous
Obsidian and coal are both rocks and they are formed by lava
Obsidian is a volcanic or igneous rock. It is formed when lava dries up.

An obsidian scalpel is constructed exactly the same way the early humans made stone knives. A skill stoneworker uses a pressure flaking technique to force a small flake of obsidian from a larger stone. The flake is examined to see if it is a suitable shape for a blade - if not the flake is discarded and the stoneworker gets another flake from the stone. Although very sharp the obsidian blade is very thin and cannot withstand lateral force on the blade. Surgeons must be very careful to cut only soft tissues with the obsidian scalpel. Attempting to cut or scrape bone could result in breakage, which could leave obsidian flakes inside the patient.

A snow flake.
Well it is a tool/rock made from volcanic glass. The Aztec used it a lot to build statues and shelter. Obsidian is well suited to 'flaking" or "napping" which is the art of creating a sharp edge. Obsidian will flake down to a molecular edge, being a type of naturally occurring glass it is high on the hardness scale. Even today, some surgical scalpel tips are fabricated from obsidian.

By flintknapping flintknapping is the art of making stone tools you can Use a hammerstone to break a rock and a sharp flake comes off You can use as a knife the best thing to use is obsidian and flint
fruit flake
It takes 4 minutes and 10 seconds for any other tool than a Diamond Pickaxe to break an Obsidian block, and no block is dropped.
Obsidian is a felsic glass. At depth, it will crystallize to form granite. On the other hand it turns into perlite on reacting with water. At high grade it recrystallizes to form felsic glass.

A Macuahuitl (hand-wood) was a sword with sharp obsidian blades embedded in its sides. They were very sharp and could decapitate a horse. A Huitzauhqui was a wooden club inlaid with obsidian blades.
