An unidentified object made a hole in the balcony glass of the Annunciation
On May 23, in Blagoveshchensk in the house No. 5 on Teatralnaya Street, residents of one of the apartments heard an incomprehensible clap outside the window. When the balcony glass was inspected, a neat round hole 10 centimeters in diameter was noticed. The owners of the apartment assume that it was a ball lightning.
In the afternoon in the apartment on the third floor about 16 hours the woman heard a strange clap, but looked out, did not notice anything. When the owner returned home, he looked more closely at the balcony and saw a round hole in the glass. The man called the police.
The arriving policemen inspected the scene of the incident, but the inspection will not be carried out, as the host refused to write the application. According to the owner of the apartment, there is no reason to believe that the hole was made by any projectile – the edges of the glass were smooth, as if melted. Around were small fragments. Another round hole, no more than one centimeter in diameter, was discovered later. The owners of the apartment decided that they had been visited by ball lightning.
The weather forecasters do not deny the possibility of a ball lightning in principle, but in this case they doubt that it could arise. “The weather on May 23 was cool – about +16 degrees in the afternoon, cloudy, weak short rain, there were no thunderstorms. The north wind is temperate. Quite strange would be the appearance of lightning without a thunderstorm, – commented the situation weather forecaster Svetlana Kazachinskaya. – Nevertheless, there are ball lightning in the Amur region.

We remove from the list ball lightning, and mechanical effects.

Why is the glass touched? The frame is not touched, the wall untouched, the site is not touched from outside.
The glass is melted in special furnaces. This quartz sand melts at a very high temperature – 1700 degrees! Here it is necessary soda. After all, with its help the melting point of sand is reduced by half.
Quartz (German Quarz) is one of the most abundant minerals in the earth’s crust.
In its pure form quartz is colorless or has a white color due to internal cracks and crystal defects. Elements-impurities and microscopic inclusions of other minerals, predominantly iron oxides, give it the most diverse color. There are many varieties, among which are almost black morion, purple amethyst, yellow citrine, etc. The reasons for the coloration of some varieties of quartz have their own specific nature.
Often forms twins.
It dissolves in hydrofluoric acid and alkali melts.
Melting point 1713-1728 ° C (due to the high viscosity of the melt, the determination of the melting point is difficult, there are various data).
Quartz crystals have piezoelectric properties; they develop an electric potential upon the application of mechanical stress. An early use of this property of quartz crystals was in phonograph pickups. One of the most common piezoelectric uses of quartz today is as a crystal oscillator. The quartz clock is a familiar device using the mineral. The resonant frequency of a quartz crystal oscillator is changed by mechanically loading it, and this principle is used for very accurate measurements of very small mass changes in the quartz crystal microbalance and in thin-film thickness monitors.
Dielectric and piezoelectric.
Dielectric (insulator) (from the Greek dia – and electric – electric) – a substance (material), relatively poor conductive electric current.
Piezoelectrics are dielectrics in which the piezoelectric effect is observed, that is, those that can either deform the electric charge on their surface (direct piezoelectric effect) or deform (under the influence of an external electric field) (reverse piezoelectric effect). Both effects were discovered by the brothers Jacques and Pierre Curie in the years 1880-1881.
That is, some technology reacted only to pure quartz in the glass, perhaps because of electrical properties. But this does not explain where the withdrawn glass disks went out of the window.
Consequently, there are other properties that are measured by other kinds of science.
Quartz in its pure form can, record information, perhaps someone needs information about the residents of this house, where everything happened.
