Glass is a non-crystalline amorphous solid that is often transparent and has widespread practical, technological, and decorative usage in, for example, window panes, tableware, and optoelectronics. Scientifically, the term "glass" is often defined in a broader sense, encompassing every solid that possesses a non-crystalline (that is, amorphous) structure at the atomic scale and that exhibits a glass transition when heated towards the liquid state.
The most familiar, and historically the oldest, types of glass are based on the chemical compound silica (silicon dioxide), the primary constituent of sand. The term glass, in popular usage, is often used to refer only to this type of material, which is familiar from use as window glass and in glass bottles. Of the many silica-based glasses that exist, ordinary glazing and container glass is formed from a specific type called soda-lime glass, composed of approximately 75% silicon dioxide (SiO2), sodium oxide (Na2O) from sodium carbonate (Na2CO3), calcium oxide, also called lime (CaO), and several minor additives. A very clear and durable quartz glass can be made from pure silica which is very tough and resistant to thermal shock, being able to survive immersion in water while red hot. However, quartz must be heated to well over 3,000 °F (1,650 °C) (white hot) before it begins to melt, and it has a very narrow glass transition, making glassblowing and hot working difficult. In glasses like soda lime, the other compounds are used to lower the melting temperature and improve the temperature workability of the product at a cost in the toughness, thermal stability, and optical transmittance.
...Let's go...
I've been lovin' u for here long knowin' I was never clear
But I have no fear today cause I'm gonna say
What I gotta say, I don't wanna play the role
Bustin' through the door, I'm gonna take ur heart fo' sure, oh
Put ur hands up in the air, it's a stick up
I'm gon take ur heart from here, now let's fix up
Put ur hands in the air, in the air, in the air
I'm gonna play my cards from here
And take this gamble sure
My words are gonna fumble, but this beat is mighty humble
Ain't goin nowhere, sure I'm scared but my life's a dare
And baby u just got so much flare, we'll be the perfect pair
I'm gonna share my mind with u, u've been blinded
My life's been blue, I'm takin u, I'm takin u
Put ur hands up in the air, it's a stick up
I'm gon take ur heart from here, now let's fix up
Put ur hands in the air, in the air, in the air
Put ur hands up in the air, it's a stick up
I'm gon take ur heart from here, now let's fix up
Put ur hands in the air, in the air, in the air
In the air, in the air, in the air
When I first met u, I wanted to wet u
Not a gun but a different content, sexual
U tried to run, I still get u
Steel metal not needed, a whole 'nother meaning
Don't want ur gold, want ur soul
Control ur heartbeatin, cause when I start squeezin that muscle
That's the trigger, than I got u nigga, in ya
Chopper spinners, got ur bodyguards wit cha
Diamond dog tag chain swingin, I had them thangs ringin
This is a robbery, no one's gettin free
Till that man, he comes with me
Put ur hands up in the air, it's a stick up
I'm gon take ur heart from here, now let's fix up
