Jewish measure

from Wikipedia, the free encyclopedia

The Jewish measure was a south German, especially a Bavarian glass measure . The measure was used in the glassworks and mirror manufacturers in Bavaria , such as in Fürth , Schönbrunn , Lambach , Ludwigsthal , Grafenau , Klingenbrunn and the Althütte in Zwiesel . Other glassworks as far as Bohemian were familiar with the measure.

A distinction was made between single and double Jewish dimensions and the so-called inch glasses . The dimension designation is said to go back to the Jewish traders and main buyers of these goods. There were extensive exports to England and France , so that the table sizes were given in the dimensions of these countries. The Brabant customs were almost the same as the Bavarian decimal. The term Jewish measure mirror was for mirrors measuring 11 "by 8" (simply JM) and (double JM or Bandel) measuring 16 "by 10".

The Jewish measure was also the basis for determining the materials required for mirroring, such as mercury , tin and foil and other basic materials, but also for determining wages. To simplify the determination of the size, the addition dimension was used, i.e. the length and width of the mirror panels were added.

Simple Jewish measure

All mirror glass panels up to 9 by 7 inches (Brabanter) or 10 ½ by 8 ½ inches (English) or 10 by 8 inches (French) were counted as a simple Jewish measure.
