processing techniques


Forming the furnace by glassmakers: Processing of single or multi-colored, hot glass. Applizierungen prunts by melting or glass fibers ("Conditions"), partial melting of feet, etc. off of thin, colored pads with a sharp iron to feathery patterns.

 Piercing of air bubbles by means of a nail or piece of wood submerged in water (evaporation in glass). Bubbles and edit low-melting glass by glass blowers "in front of the lamp" instead of the stove (= fan lamp; bellows) homework. Softenable easily melt through clay accessories: None crystallization, no devitrification when re-heating.

 Since the Umpicken omitted, missing a demolition. Processing - often of colored glass - by blowing and melting. Needles and forceps as attachments. Used in Venice since the 17th Century in Germany. Also in the form of pulled-glass spider threads.

 Hot and cold finishing within the glassworks:

 Mottling of the mass by melting and stirring different colored glass.

 Glass thread: Stripped pattern by lining melting colored rods or parallel
 out or reticulated threads, eg as frosted glass insert. Rotated pattern by twisting the glass bubble.

 Frosted glass: ice-like cracking. Achieved either by quenching the mass in cold water or by rolling the Kölbels on - even color - glass splinters followed Verwärmen.

 Flashed different colored blown glass the glass furnace, as internal or external overlay. Kameoglas.

 Processing methods outside the glassworks:
 Cracked diamond, linear ornamentation of the cold glass, from 1534 - Diamond and Stahlpunktierung.

1.Kaltmalerei. Cold painted with oil paints resin additives. No burning.
2.Wenig resistant.
3.In small muffle furnaces (in Vedendig; within the cottage) be fired
4.Gold or silver. Even as a deposit. Drawing by engraving, by gentle luster polishing. Sensitive to mechanical influences.
5.Aufgebrannte Schwarzlot. Dull surface. Relatively insensitive.
6.with the brush applied and been burned in a muffle furnace at 500 ° C, opaque enamel colors of coloring, also clouding metal oxides. Flux: quartz and potash. Insoluble.
7.Transparente enamel colors: Through greater proportion of fluxes than in enamel colors.

Glass: Radschliff on the cold glass. Grinding of facets, such as grinding of shells or Kugelungen. Pressing the glass to large, rapidly rotating horizontal iron discs (flat glass for all areas). Drive through Radzieher the flywheel or mechanically
 by hydropower. Machining utilizing abrasive powder (sand, emery) and water.
 Ornamental engraving on the edges of large, vertically running stone and wooden wheels.

 Gradations Rauh or coarse sanding, clean or clear-cut. Polishing and Blänken by pumice. Stannic oxide, cork, felt, leather and lead or
 Wooden discs. Classification of workmen Square in rubber / facets Schneider and Kugler
 (Balls and olives).

 Cut shapes: arches, eyes, Brilliant, faces, hair, hollow, wedge, sphere. Olive, ornament diamond, peel, star, rays, turban, honeycomb and roller grinding. Stones lungs, Brilliantierung.

 Glass section: Radschnitt the cold glass with small and therefore mobile, relatively slowly rotating cutter.
 Low cut: Submerged engraving ("cutting") of decorative patterns by means of a
 Treadle powered, horizontally rotating copper wheel using oil
 and Emery.

 The glass is held-with impaired vision freely by hand and by eye
 decorated; most pressing a drawing or an engraving on the inside wall
 of the glass. Matt always cut. Semi-matt-section through the use of wooden wheels.

 Polished section through use of lead wheel.
 Matt Gerutschter section: Flat surface roughening instead of cutting decor.
 High cut: Tedious,-abrasive erosion of the ground relief, only chalk and
 Lead Glass applicable. Corresponds to the Kameotechnik of stone cut, was also court art.
 First water-powered grinding plants in Silesia (from 1680), Potsdam (1687), Kassel (late 17th century) and Dresden (1697).
