Soda–lime glass (for containers) [2] Borosilicate (low expansion, similar to Pyrex, Duran) Glass wool (for thermal insulation) Special optical glass (similar to Lead crystal) Fused silica Germania glass Germanium selenide glass Chemical composition, wt% 74 SiO 2, 13 Na 2 O, 10.5 CaO, 1.3 Al 2 O 3, 0.3 K 2 O, 0.2 SO 3, 0.2 MgO, 0.01 TiO 2, 0. ...
Books 1-4 feature the characters as they appeared in the 1986 edition of the board game. From Book 5 onwards, the character redesigns from the 1992 edition were used. Mr. Boddy is a wealthy philanthropist and a painfully trusting host. He collects valuable items while generously forgiving his guests for attempting to commit any crime, including ...
The refractive, reflective and transmission properties of glass make glass suitable for manufacturing optical lenses, prisms, and optoelectronics materials. Extruded glass fibres have applications as optical fibres in communications networks, thermal insulating material when matted as glass wool to trap air, or in glass-fibre reinforced plastic ...
Batch processing is one of the initial steps of the glass-making process. The batch house simply houses the raw materials in large silos (fed by truck or railcar), and holds anywhere from 1–5 days of material. Some batch systems include material processing such as raw material screening/sieve, drying, or pre-heating (i.e. cullet). Whether ...
Parker has written or edited over 50 books, a series of puzzle books for the For Dummies brand, 25 digital games, the annual USA Today Crossword Calendar, and the syndicated Family Time Crossword. In 2014, Parker co-wrote The Book of Revelation Made Clear with the co-creator of the Left Behind series, Tim LaHaye .
Additional ingredients may be added to color the glass. For example, an oxide of cobalt is used to make glass blue. [3] Broken and scrap glass, known as cullet, is often used as an ingredient to make new glass. The cullet melts faster than the other ingredients, which results in some savings in fuel cost for the furnace. Cullet typically ...
Frit. A frit is a ceramic composition that has been fused, quenched, and granulated.Frits form an important part of the batches used in compounding enamels and ceramic glazes; the purpose of this pre-fusion is to render any soluble and/or toxic components insoluble by causing them to combine with silica and other added oxides.

Warm glass is rolled on the marver, both to shape it and as a means of temperature control. [3] With a high specific heat capacity , the surface absorbs heat from the glass; because of the relatively slow flow of heat through the glass, it does so particularly from the outermost material, forming a more viscous skin.
