Deformation (glass)

a glass container defect representing a change in its shape as a result of violation of the formation and (or) heat treatment modes.

corolla deformation

ovality of the body - deformation of the glass container in the form of a deviation from the circularity of the cross section of the body.

corolla ovality - deformation of a glass container in the form of a deviation from the circularity of the cross section of the neck corolla.

concavity of the corolla end - deformation of the glass container in the form of a deviation from the flatness of the end of the corolla of the neck.

Disk voltage standard

a glass disk with calibrated birefringence is used as a comparative measure in determining the degree of annealing of glass.

Distraction

The second stage of grinding glass - fine final grinding, performed after grinding

Diffusion paint

Ceramic paint based on a mixture of coloring metal salts (mainly silver and copper) and a binder, diffusing (entering into a chemical reaction) with glass molecules on the surface

Diffusion (color etching, color etching)

A method for modifying a glass surface in which metal ions diffuse into the surface layer of glass

Burn out

Method for cleaning chimneys (hogs) supplying gas by afterburning

Bottom bars

Refractory bars forming the bottom of the bathroom furnace

Additional heating (Boost melting)

An auxiliary method of heating a gas or liquid fuel furnace by passing electric current through a glass mass

Additional electric heating (Boosting)

An auxiliary method of heating a gas or liquid fuel furnace by passing electric current through a glass mass

Drapery (swelling on glass)

A method of forming heated glass, in which it swells on the outside of the glass mold

Drot

Thin glass rods (mainly of circular cross section) or small and medium diameter tubes that are used in the manufacture of ampoules, art products, Christmas toys, as well as decorating glass products during thermal molding
