If the load is uniformly distributed over the area it needs to be 0.21 inch thick using a safety factor of 5 on the glass strength to account for flaws. The support at the corners must not be a point load but rather distributed by a soft or plastic pad
Yes, a thick piece of glass is a better insulator than two thin pieces of glass with air in the middle. This is because heat transfer is reduced as the thickness of the insulating material increases, creating a greater barrier to heat flow.
thick commercial glass panels formed under pressure. when cooled the temsion of the pressure is locked into the crystal structure making them very resistant to damage from a blow to their faces (but not to their edges and edge corners)

You need to know the area of the glass, its span, how it is supported, and how thick it is; also you need to know the stiffness of the tennis ball; so this is a complex problem.
concave lense is a piece of smooth glass that is thick from the edges and thin from centre and is used to diverge light rays.
A thick piece of wood is commonly referred to as a plank.
It is 10 mm thick.
there is no difference between a thick glass bong and a thin glass bong except i guess the thing breakes easier
The glass typically used in picture frames is about 2mm to 3mm thick.
It varies from 2-75 inches thick.
it's called a peice of string
