Wired glass is a type of glass into which a wire mesh is embedded during production. Wired glass has an impact resistance similar to that of normal glass, but in case of breakage, the mesh retains the pieces of glass. This product is traditionally accepted as a low-cost fire-resistant glass. Wired glass can be tinted by aerosol or electricity. Common colours are golden-yellow, green, light blue and violet-rose.

Wired glass is manufactured primarily as a fire retardant, with wire mesh inlaid in the glass to prevent it from shattering and breaking out under stress or when exposed to high temperatures. With the window intact, the glass keeps the fire at bay, protecting those on the other side from the harmful effects of smoke and flame.

However, in recent times, experts warn against the use of wired glass as a fire-resistant substance. This because although the mesh may prevent the fire from penetrating, by itself it could prove dangerous, being made of fine, sharp wires which can hurt. Today, special fire-resistant glass is available, which is devoid of the wire mesh as a component and can cut off not just the fire but even smoke, gases and deadly radiant heat.

Wired glass is made as a part of the rolled glass manufacturing process. Rolled glass is manufactured by passing molten glass from a furnace through a series of rollers to obtain the desired thickness and pattern. The rolled glass process is used to create wired glass, figured or patterned glass, and art/opalescent/cathedral glass.

Wired glass is produced by continuously feeding wire mesh from a roller into the molten glass ribbon just before it undergoes cooling. A steel wire mesh is sandwiched between two separate ribbons of semi-molten glass, and then passed through a pair of metal rollers which squeeze the "sandwich of glass and wire" together. Wired glass may be further processed by grinding and polishing both surfaces, producing "polished wired glass”.
