“…115 Window glass produced after c. 1930 contains 2.7-4.1 wt% MgO. 116 There is the possibility that phase 5 can be divided into two subphases based on the MgO concentration. The MgO concentration shows a strong bimodal distribution with one group containing 2.7-3.0 wt% MgO and the other with 3.5-4.1 wt% MgO.…”

This article reviews the nature of window glass employed in historic buildings in England over the past fi ve centuries and presents new results on the nature of that glass. Chemical analysis of available samples has shown that window glassmaking technologies have changed over time. This provides information which can be used to identify the period of the manufacture of particular panes of glass. It is hoped that the use of chemical analysis to date historic window glass in this way will be used to enhance building conservation decisions.

“…Table IX shows a commercial control and three of seven modifications, which had been reported. Examples 1 to 3 in Table IX are Examples 3, 6, and 7 of Table 6.15 in the original book chapter by Smrček 26 . Specifically, the examples document the addition of Al 2 O 3 to the composition of a commercial control because it is expected to raise the chemical resistance.…”

“…The analysis provided in Table VI 26–28 includes viscosity (dPa s), operating temperature (°C), and duration (time) of individual operations and the cooling rates after completion of the thermal treatment (°C/s). The viscosities above the liquidus temperature range from 10 3.6 to 10 4.0 dPa s, the operating temperatures below the liquidus temperature range from 200° to 1040°C.…”

“…A series of new energy‐saving container glass compositions was reported in 2010 26 . It had been derived by a structured trend line design approach, that is, by a carefully designed exchange of %SiO 2 for %Al 2 O 3 accompanied by a slight increase in %CaO and %Na 2 O.…”

The liquidus temperature plays an important role in the manufacture of fiberglass and glass melts and in the design of new energy‐saving commercial compositions, which must be formulated to be crystallization resistant, possess a lower operating temperature and require less energy than incumbent commercial compositions. In the manufacture of glass melts and glasses, the temperature at the furnace exit must be above the liquidus temperature to avoid crystallization and many operations beyond the furnace exit are carried out below the liquidus temperature. This paper establishes the relationship between liquidus temperature and operating temperatures in various process steps and analyzes the parameters, which are required for the manufacture of new and more energy‐saving variants.
