The Mirror Crack'd is a 1980 British mystery film directed by Guy Hamilton from a screenplay by Jonathan Hales and Barry Sandler, based on Agatha Christie's Miss Marple novel The Mirror Crack'd from Side to Side (1962). It stars Angela Lansbury, Geraldine Chaplin, Tony Curtis, Edward Fox, Rock Hudson, Kim Novak, and Elizabeth Taylor.
Glass disease, also referred to as sick glass or glass illness, is a degradation process of glass that can result in weeping, crizzling, spalling, cracking and fragmentation. [ 1 ] [ 2 ] Glass disease is caused by an inherent instability in the chemical composition of the original glass formula. [ 3 ]
Dealkalizing glass containers is accomplished by exposing the glass surface to reactive sulfur- or fluorine-containing compounds during the manufacturing process. A rapid ion-exchange reaction proceeds that depletes the inside surface of alkali, and is performed when the glass is at high temperature, usually on the order of 500–650 °C or ...
Unless stated otherwise, the properties of fused silica (quartz glass) and germania glass are derived from the SciGlass glass database by forming the arithmetic mean of all the experimental values from different authors (in general more than 10 independent sources for quartz glass and T g of germanium oxide glass). The list is not exhaustive.
Alkanes are broken apart at high temperatures, often in the presence of a zeolite catalyst, to produce a mixture of primarily aliphatic alkenes and lower molecular weight alkanes. The mixture is feedstock and temperature dependent, and separated by fractional distillation.
Typical French craquelure in a portrait from c. 1750, larger and less regular patterns, with curving cracks. Painting systems are composed of complex layers with unique mechanical properties that depend on the type of drying oil or paint medium used and the presence of paint additives, such as organic solvents, surfactants, and plasticizers.
The heaviest alkanes in petroleum and natural gas are cracked into lighter molecules which are dehydrogenated at high temperature: C 2 H 6 → C 2 H 2 + 2 H 2 2 CH 4 → C 2 H 2 + 3 H 2. This last reaction is implemented in the process of anaerobic decomposition of methane by microwave plasma. [21] [non-primary source needed]
Tollens' test for aldehyde: left side positive (silver mirror), right side negative Ball-and-stick model of the diamminesilver(I) complex. Tollens' reagent (chemical formula ()) is a chemical reagent used to distinguish between aldehydes and ketones along with some alpha-hydroxy ketones which can tautomerize into aldehydes.
