Ancient glass in minnesota collections - Roman glass - Wikipedia



Customers from Greece proudly informed us about this incredible finding with their geophysical instrument Rover C. Although if non-metallic, the device Rover C located this glas vase as an underground anomaly in the measured area. Determination of position and depth of this ancient target was also possible due to the 3d software program. The vase has been detected in a depth of about 1 m in neutral soil conditions.

Treasure hunters are using the 3d metal detector Rover C to detect all kinds of metal and treasure like gold silver and iron.

OKM is manufacturer of metal detectors, ground penetrating radars, geoelectrical instruments as well as other detection technologies.

In addition to this a major new technique in glass production had been introduced during the 1st century AD. [7] Glassblowing allowed glass workers to produce vessels with considerably thinner walls, decreasing the amount of glass needed for each vessel. Glass blowing was also considerably quicker than other techniques, and vessels required considerably less finishing, representing a further saving in time, raw material and equipment. Although earlier techniques dominated during the early Augustan and Julio-Claudian periods, [8] by the middle to late 1st century AD earlier techniques had been largely abandoned in favour of blowing. [1]

Roman glass production relied on the application of heat to fuse two primary ingredients: silica and soda. [7] Technical studies of archaeological glasses divide the ingredients of glass as formers, fluxes, stabilisers, as well as possible opacifiers or colourants.

Roman glass has also been shown to contain around 1% to 2% chlorine, in contrast to later glasses. [10] This is thought to have originated either in the addition of salt (NaCl) to reduce the melting temperature and viscosity of the glass, or as a contaminant in the natron.

It is still not known about man's first efforts to make glass. It is believed that the Egyptians were among the first to use glass in their art and culture. As far back as 2500 BC, amulets and solid glass beads were made in Mesopotamia. About 1000 years later, the Egyptians also began making glass. Glass is produced from a mixture of silica-sand, lime and soda.

Pure glass as a separate material, in the form of translucent beads, came later in predynastic period. In the Old and Middle Kingdoms glass jewelry, amulets, little animal figures, mosaic stones and similar things were made.

The first glass vessels were made during the reign of Tuthmosis I in the New Kingdom. This innovation came to Egyptians probably due to their expansion in the Middle East.
