Pressed glass tends to be smooth not sharp. I don't know a whole lot. My friends and I are just starting.
cut glass is just that. The pattern is cut into the glass with an abrasive coated metal wheel and polished. pressed glass is when a hot gob of glass is pressed into a patterned mold. These molds are often patterned like cut glass to produce cheap and widely affordable similes of the much more expensive cut glass.
cut glass is very smooth and polished, whereas pressed glass is made in a mold and will present two seam lines at opposing sides of the glass. Often, but not always, it will show some "chill marks" as slight rippling on the flat planes.
Pressed Glass is used for many different glass products. Such as Domestic and Decorative purposes. It's used for paper weights, glass ware, and vases to name a few items.

Pressed glass can contain lead, but it depends on the specific type and manufacturer. Some pressed glass items, particularly those made before the 1980s, may have been produced using lead-based materials for clarity and brilliance. However, many modern pressed glass products are made without lead to comply with safety regulations. It's always best to check with the manufacturer or look for labels indicating whether a product is lead-free.

The movement of water upward through two glass sides pressed together demonstrates adhesion and capillary action. Water is the most important compound on the Earth.
Faux crystal is normally pressed glass rather than hand cut. You can normally tell by finding the mold seams in the glass.
No. First of all, you would be hard pressed to find "lava proof glass." Second, magma (what lava is called underground) does not melt is way through rock; much of the time it fractures the rock, as it works its way up under enormous pressure. Even then, it can find another rout to the surface.
