What is wing apparatus in chemistry?
In chemistry, the wing tip apparatus is used to spread the flame over a large area on a glass tubing. This will result to a uniform bending in glass.
How do flame retardants prevent fires?
Flame retardants reduce the spread of fire on a material by raising the temperature at which it will burn. There are several physical chemistry approaches to reducing flame spread, but see the wikipedia article for more details.
Why is vertical flame spread more rapid than horizontal flame spread?
The heat from a fire in the vertical spread is traveling upward and preheating the fuel about to be burned; whereas in horizontal spread, most of the convective heat is escaping into the atmosphere. Only the radiant heat is warming the material to the side.

Why is the sodium flame is not visible through the cobalt glass?
The cobalt glass blocks distracting and common yellow fire, it serves as an optical filter in flame tests, to filter the yellow flame cause by contamination of sodium
Why glass rods are used for flame tests in inorganic qualitative analysis?
It is not used in organic analysis due to the imparting of yellow color to the flame by silicates in the glass rod.
What is the fire rating for tempered glass?
Standard toughened glass is class 0
