Diatoms
Diatoms are microscopic plants (phytoplankton) found in oceans and lakes. Their cell wall is made of Silica which remain after the diatom dies. Diatoms are single celled, photosynthetic algae this means that they are producers!!
Diatom cell walls are composed of silicon dioxide.
I believe you a thinking about Diatoms. They have a shell, not a cell wall, made of silica, the same material glass is made of. They are a spectacular sight under a microscope. Because of their Strong rigid shell and reflective properties they are used in many commercial products like reflective paints, abrasives, and formerly cosmetics.
Opal is made of silica, but it technically is not a mineral.

The basic idea is that glass is made out of heated sand, which is silicon dioxide and the key part of that is the silicon.Chemicals for making common glass are Silica (silicon dioxide, the glassy part), and Sodium Carbonate (Soda Ash), lowers the melting point.
A cell wall can be seen in kingdom protista.It may consist of cellulose,silica,agarose,agar,algenic acids
what type of plant cell would you expect to find in the photosynthetic tissue of a leaf?
Glass is silica dioxide. It is made by melting silica sand.
silica or silica sand
Opal is made of silica, but it technically is not a mineral.
