Obsidian, a naturally occurring volcanic glass, is naturally black in color.
Hydrofluoric acid is commonly used as an alkali to etch glass due to its ability to react with the silica in glass and create a frosted appearance. However, hydrofluoric acid is highly toxic and corrosive, requiring careful handling and safety measures.
No, glass cannot get into your bloodstream. If you have a cut from broken glass, the body will naturally expel any small glass fragments.
Glass is mostly made of silica (SiO2). Silica is molecule, not an element, but in that case the most abundant element is oxygen, being that there are 2 oxygen atoms (O) to every 1 silicon atom (Si).
They are not naturally occurring
Gorrila glass is a "Corning" manufacturing product. It is a alkali-aluminosilicate sheet of glass. Basically, it is meant to be highly thin and resistant to much surface damage. It is mostly chemical strengthened glass.

Seeded Glass has pinhead sized bubbles. The glass softens the light coming from the bulb inside and replicates the naturally seeded glass made in colonial times.
Si - silicon.
That would be silicon, or SiO2
