How long can glass last in its natural state?

It can exist for hundreds of years, but after a certain period of time, it will still be corroded by the natural environment.

Hundreds of years can exist for hundreds of years in the natural state, and as long as the environment is stable, the state of the glass is also stable.

It can exist for a long, long time in its natural state because its structure is very stable.

It is basically impossible to degrade under natural conditions, and the time is too long. It can't be degraded for a long time.

I feel like it should always exist without being damaged by the outside world.

I think it can always be there, because it's made of very hard ingredients.

I think it should be tens of hundreds of years, as long as it is not damaged by the outside world.

The main component of glass is silica, which is very stable and does not decompose easily, and many studies have shown that glass can exist for more than 1,000 years or more in the natural environment.

In its natural state, glass has a lifespan of up to 1 million years.

The main components of glass are calcium carbonate, sodium carbonate and silica, none of which are necessary for biological growth and development, and the "decomposers" of degradable species are not able to eat glass, so it is impossible to biodegradable glass.

Glass is a non-degradable substance, meaning that it is almost impossible for glass to degrade in a short period of time under natural conditions. This is because the chemical structure of the glass is extremely stable. There are no microorganisms in nature that can degrade glass.

"It is estimated that it takes more than 1 million years for glass bottles to decompose in the natural environment, but the accumulation environment in landfills is more protected, so glass will decompose for a longer time. ”

Glass, like quartz, is mainly composed of silica, but quartz is crystalline, while glass is not. Another form of glass and quartz is equivalent, the amorphous silica chalcedony. Chalcedony, like glass, is formed by the rapid cooling of a high-temperature molten melt, but it is too late to crystallize.

Therefore, glass and chalcedony have a tendency to crystallize, and they will both develop towards embryonic crystallization, <>

It's just that this transformation is very long under normal temperature and pressure, but it is not as long as millions of years! If you can find the glass of the old buildings in the forties and fifties of the last century, you will find that these glasses are very turbid, and some even grow radial lines similar to the pine flowers in the pine eggs, which is the embryonic crystallization of glass, and the crystallization is followed by the crystallization. The thicker the glass, the more obvious this phenomenon is, so the glass cannot be preserved forever.

The chemical composition of glass is very stable, and some data say that glass has a lifespan of up to 1 million years in its natural state. In the natural state, the glass will not be affected by sunlight, rain and fog, and its performance will be attenuated; Ordinary acids and alkalis do not cause harm to glass. Glass artifacts found in the Egyptian region date back to the 13th century BC, and older glass may have even been made in what was once Mesopotamia.

It doesn't exist for too long, mainly because it will soon be eroded by wind on the surface, and it will take a little longer to be buried in the soil or thrown into the deep sea, but it still can't avoid the movement of the earth's crust, such as friction with the surrounding soil, **, volcanic eruptions.

Mineral stones such as glass, porcelain, and pottery may have the same longevity as the stones on the earth if they are preserved in better conditions, such as after burial, and glass porcelain is more dense, crystallized better, less prone to oxidation, and may have a longer lifespan, up to 100 million years.

To tell you exactly, glass is a liquid, but the molecules move very slowly and appear to be solid.

When a piece of flat glass flows like glue, it takes 200 million years.

It takes 4000 years for complete degradation. In other words, glass does not naturally dissolve in the soil like ordinary non-hazardous garbage. However, landfill treatment cannot change the existence of waste glass, and it will still bring many potential insecurity to the natural environment.

Glass can exist almost permanently in its natural state, and it is non-degradable because it is itself a silica product and can no longer be oxidized.

Generally, glass can be retained for a long time in its natural state, at least for about 100 years, and it is difficult to degrade.

In its natural state, glass has a lifespan of up to 1 million years. A lot of people, including me, were scared by this statistic. However, if you think about it, the data of 1 million years does not mean anything to humans.

Physical tempering is to heat the glass and then quench it, which changes the structure between the molecules inside the glass; Chemical toughening is the ion exchange of the molecular structure of the glass surface at high temperatures; Both methods permanently alter the microstructure of the glass material. Therefore, unless there is a high temperature and strong chemical effect, the toughened properties will not decay or change over time under normal use.

In fact, in ancient China and ancient Europe, a lot of glass artworks have been handed down, many unearthed glassware, although after more than 1,000 years, but the color is bright, intact, it can be seen that the chemical properties of glass are very stable in the natural environment.

For example, glass objects found in Egypt date back to the 13th century BC, and older glass may have been made in what was once Mesopotamia.

Glass has a high chemical stability. It is not eroded by bacteria, microorganisms, weathering, water erosion, and it can be said that in nature, nothing can decompose it. However, if the glass is artificially subjected to aggressive media for a long time, it can also lead to deterioration and destruction.

How long does it take for a piece of broken glass to become non-sharp, that is, how long does it take for the inner edge to become rounded.

If a piece of broken glass, its edge is in a state of wind and sand, under the corrosion of various acid rain, it will ...... after hundreds of years

Its edges have become rounded, and it will not be easily cut, so how much difference is there between such glass and marble, shells, etc.?

In today's life, glass products and accessories have penetrated into all aspects of people's lives, the most common such as glass cups, glass windows, glass microscopes, astronomical telescopes for scientific research, glass screens in electronic products, and many contemporary glass artworks.

Glass can also be environmentally friendly, from its composition and processing process is not difficult to see, as long as it is reheated, broken glass can be reshaped, can be rejuvenated.

It can generally survive for hundreds of years. First of all, the chemical structure of glass is relatively stable, and if it is not in a humid or high temperature state, glass can exist for a long time in its natural state.

In fact, glass can exist for a long time in a normal environment, because glass is very stable, but when the glass is in a continuous humid environment, it will appear moldy and other conditions, and often disappear in a few months.

I believe that glass can exist in its natural state for up to 1 million years, which is determined by the environment in which it is located.

The main components of glass are calcium carbonate, sodium carbonate and silica, and the components of glass cannot be degraded by photo, nor can they be degraded, so glass has no life at all.

Glass can be stored for a long time in its natural state, at least one or two hundred years, and is a very corrosion-resistant item.

In its natural state, the lifespan of glass is up to 1 million years, and its chemical composition is very stable, and there is no degradation of performance in the natural state.

Glass is a non-degradable substance, so it has no "lifespan" unless it is broken.

1. Good see-through and light transmittance (the visible light transmittance of 3mm and 5mm thick lens glass is 87% and 84% respectively). The transmittance of near-infrared heat rays in sunlight is high, but it can effectively block the far-infrared long-wave heat rays generated by the refraction of visible light to the indoor wall roof, floor, furniture and fabrics, so it can produce an obvious "warm room effect". The net glass has a low transmittance to ultraviolet rays in sunlight;

2. Sound insulation and certain thermal insulation performance;

3. The tensile strength is much smaller than the compressive strength, which is a typical brittle material;

4. It has high chemical stability, under normal circumstances, it has strong resistance to acid, alkali salt and chemical kit gas, but long-term exposure to aggressive media can also lead to deterioration and destruction, such as weathering and mildew of glass will lead to appearance damage and reduced light transmittance;

5. The thermal stability is poor, and it is easy to explode in extreme cold and heat.

I asked, can glass degrade? Why are you giving me a bunch of nonsense?
