How To Really Make Glass From Sand - Survival Manual

To actually make the glass the three ingredients are placed in a clay pottery crucible. The crucible is placed on a ledge inside a kiln and a fire is lit. Eventually the fire turns the sand/potash/limestone into glass. When cooled down you have a glass ingot. Link:How to build a kiln aka furnace. Kiln.

How Glass is Made — SGS

The main raw material used to make glass is sand. To make clear glass, a special sand called silica sand is used. This fine white sand is needed because it is very pure and does not contain other unwanted chemicals. It is “washed” to remove as many impurities as possible, as impurities can adversely affect the clarity and color of the glass.

How Is Glass Made: A Step-by-Step Process

2018-4-3  Next, in order to remove the internal stresses built up in glass, a process called annealing is done. This process allows the glass ribbon to pass through a layer which eliminates any stresses on the glass surface and gradually cools it to give it its final hardened form. This makes it easier to cut the glass and shape it accordingly. 5.
