Charred wire

Reinforced glass defect in which the surface of the wire is heavily contaminated with oxide

Peeling

The first stage of grinding glass - rough primary grinding, performed before distribution

Bleach

A substance or mixture of substances added to a mixture that neutralizes the coloring effect of impurities. Their action is either physical (by creating a color that complements the color of the impurity to neutral), or chemical (for example, by oxidation)

Tiling

Placement of the refractory bar outside the worn bar during operation of the furnace; or bar located in this way

Obsidian

Natural volcanic glass in black

Fire polishing

Glass heating to give it smoothness, gloss and fusion of the edges of the product

Fireproof glass (Flameproof glass)

Glass that does not break easily when heated, or in contact with a flame

Refractory bar

1. Refractory blocks placed in front of a newly installed pot.

2. Refractory bars for regulating glass flows in the channels of the forming machine (shutter).

3. Refractory bars in a vertical damper with a counterweight or in the furnace door (gate).

Scale

A small piece of metal or coal oxide enclosed in glass

Oxidizing agent

A mineral or chemical component that enhances the oxidation state of other glass components during cooking, thereby helping to brighten or control the color of the glass

Colored schliere

Dark or otherwise tinted linear inclusion in colorless or stained glass

Environment

1. Refractory blocks placed in front of a newly installed pot.

2. Refractory bars for regulating glass flows in the channels of the forming machine (shutter).

3. Refractory bars in a vertical damper with a counterweight or in the furnace door (gate).

Opal glass

Stained opaque glass

Potlets

Oven for heating pots before being placed in a pot oven

Support wall

Blocks of a special form supporting a vault or other arches

Capacity determination

Tests in which the capacity of glass containers is determined not for one product, but as the average for a representative sample

Down duct

A duct with a bottom level below the bottom of the cooking stove

Refining

The stage of the glass melting process, in which the glass melt is freed from insoluble gases

Residue (Scull)

Glass remaining in a spoon after most of the glass is poured

Vitrification

Contact surface sintering of molten glass

Heating holes

Cavity or blind holes in the pot furnace to heat the bins

Swelling (free-form glass)

The technology of forming heated glass under the influence of its own weight

Glass swelling

A method of forming heated glass, in which the glass swells on the inner surface of the glass mold

Annealing

Slow cooling of the glass after heating to remove (reduce) the internal residual stresses arising from the temperature difference between the inner and outer layers of the product

Open pot

A pot opened in such a way that the glass is directly heated and chemically attacked by the torch

Open bubble

Defective surface of sheet glass due to contact with rolls in the shaft of a vertical stretching machine

Casting

The process of shaping glass by pouring it into a mold or onto a table or by passing it between shafts

Reflective glass

This is an ordinary float glass with a metal coating to reduce solar heat. A special metal coating also gives a mirror effect that does not allow you to see through such a glass. It is mainly used in facades.

Point

A hole through which glass flows. In relation to the feeder, the term refers to the hole formed by the ring of a point (insert) at the bottom of the tray
