From the physico-chemical view is glass an undercooled and frozen melt. It consists of different composition, is not built up crystalline, but amorphous-homogeneous. It is also a name for glassy articles of the daily use.
A homogenous material with partly glassy and crystalline constitution and a particular low heat expansion. That means the material doesn’t expand by heating. This material is used in the kitchen and household as cooking plates (ceramic stove top). The cooking plates are absolutely heat resistant and resistant against temperature changes, hard, scratch-resistant and non-porous, smooth and they have a flat surface. That's why there are easy to clean. They become faster hot and transferred the heat only upwards.
Glass composition: The composition of the necessary substances for the glass melt.
Affects older hollow glasses. It is a decomposition phenomenon, caused by too humid storage. First signs are fine hair cracks and flakes, which later drop down step by step.
Grinding where motifs are "embedded" in the glass surface.
A fibrous glass product of different types and lengths, e.g., glass webs, glass wadding and glass wool. The production occur by diffuser drawing technique.
The further processing of glass, which serve for improvement and value enhancement. There are the furnace refinement and cold refinement.
Tools which are used within the glass production to cut glass when it is still soft.
The name of glass producing industrial plants. The item is clear from a time as glass was produced in the forests, close to the wood.
Glass refinement method, where coloured or clear glass threads are applied on a hot, but ready blown glass object. The applied glass threads melt down immediately.
Gob: For a process step required glass amount, which is taken from the furnace.
Decoration of a glass surface by seperating the glass in single fields of different size and depth.
