Standard Glasses for Calibrating Purposes
For calibrating purposes in physical and chemical investigations of glasses, the DGG offers the following standard glasses.
Standard Glass 1
Standard Glass 1 is a soda lime silica glass (flat glass) with precise chemical analysis of the main components. The Physikalisch-Technische Bundesanstalt of Braunschweig carried out the viscosity measurements in the temperature range of 520 to 1420 °C. In round robin tests, transformation temperature and thermal coefficient of expansion were determined.
Standard Glass 1 is available as sheets (ca. 80 mm x 50 mm x 10 mm) of ca. 98 to 100 g each.
Price: EUR 440.– per sheet of Standard Glass 1 plus VAT and shipping costs. The maximum delivery quantity per order is two sheets. For how to order, see right column, data sheet follows here.

Standard Glass DGG X
new viscosity standard
Standard Glass DGG X is close to Standard Glass 1 of the DGG and is a soda lime silica glass, too. The precise chemical analysis of the main components and some trace elements is determined within a round robin test of the sub group “glass analysis” of the technical committee 1 of the DGG “physics and chemistry of glasses”. The Physikalisch-Technische Bundesanstalt of Braunschweig carried out the viscosity measurements in the temperature range of 520 to 1420 °C. In round robin tests, transformation temperature and thermal coefficient of expansion were determined.
Since the properties of Standard Glasses 1 and DGG X are more or less similar, the known property data of Standard Glass 1 may be used for comparison.
Standard Glass DGG X replaces Standard Glass 1 as viscosity standard.
Preis: EUR 225,– per sheet of Standard Glass DGG X plus VAT and shipping costs. For how to order, see right column, data sheet follows here.

Standard Glass 2
The composition of Standard Glass 2 corresponds to that of a float glass. The chemical analysis of this glass as determined by a round robin test is available upon request. Delivery is a set of two sheets (ca. 80 mm x 50 mm x 5 mm) of ca. 50 g each.
Price: EUR 105.– per set of Standard Glass 2 plus VAT and shipping costs. For how to order, see right column, data sheet follows here.

Standard Glass 3
Standard Glass 3 is a borosilicate glass (type Duran). The chemical analysis of this glass as determined by a round robin test is available upon request. This standard glass is offered in the form of a powder (sieve analysis also available).
Price: EUR 100.– per ca. 100 g of Standard Glass 3 plus VAT and shipping costs. Note the separate contact information for ordering. Data sheet follows below.
