Н

Load (pull)

The volume of molten glass produced by the furnace in a given time (usually 24 hours)

Stress

Any state of tension or compression existing in the glass, in particular as a result of incomplete annealing, temperature gradient or inhomogeneity

Packed bricks

Refractory elements used to fill the regenerator

Sodium-calcium silicate glass (Soda-lime glass)

Glass, the main components of which are silicon dioxide, sodium and calcium oxides.

Neutral glass

High chemical resistance glass

Glass containers are not parallel

a glass container defect representing the difference between the maximum and minimum height of the glass product, determined by the distance between the highest and lowest points of the neck rim and the supporting surface.

Glass container irregularity

a glass container defect representing a deviation from the perpendicularity index of the vertical axis of the bottom plane of the product.

Bearing arch

One of several arches supporting the nozzle in the regenerator

Lower annealing temperature

the temperature at which the viscosity of the glass is 1015Pz. At this temperature, 1% of the stress is removed within 3 minutes.

Low emission glass

it is a clear glass coated with a microscopically thin film of metal oxide. This allows solar heat and light to pass through the glass into the building. At the same time, it prevents heat from leaving the room, significantly reducing heat loss.

Threaded Swill

Very thin vitreous inclusion in the glass in the form of a clearly defined filament

Feeder nose

Refractory block of a special form, equipped with a point, forming the feeding end of the feeder
