Yes, glass can absorb water. Irving Friedman and others showed that Obsidian (volcanic glass) absorbs water very slowly, and the amount of water it has absorbed can be used to date the age of a fresh cut in this type of glass. The rate of absorption of water depends on a number of factors, including the silica content of the glass (SiO2), the amount of water already absorbed, and the temperature. These factors are not necessarily the only ones affecting this process, but my current work (the amount of water absorbed by volcanic glass from New Zealand) has not yielded answers yet as to the other factors. A ballpark estimate for rate of hydration would come from using diffusion rates of around 1-10 micrometers squared per 1000 years, as suggested by Friedman et al. (1993a)
What else can I help you with?
Can we use float cullet in container glass?
Cullets doesn't float on water.
Suppose you put a birthday caddle in a glass of water why will the caddle float on top of the water?
It will float on top because it is less dense than water.
Why does a piece of glass float in mercury but sinks in water?
Glass floats in mercury because mercury is much denser than glass, creating a buoyant force that allows the glass to float. In contrast, water is less dense than glass, causing the glass to sink due to its higher density. The buoyant force in water is not enough to support the heavier glass object.
Why does ice float in a glass of water?
Ice floats in a glass of water because it is less dense than liquid water. When water freezes, its molecules arrange themselves in a crystalline structure that occupies more space, resulting in a lower density compared to liquid water. This unique property of water, where solid ice is less dense than its liquid form, allows ice to float.
What will happen if you drop a piece of chalk and a sponge into a glass of water?
The chalk will sink to the bottom of the glass, as it is denser than water. The sponge will initially float on the surface due to its lower density, but over time it will absorb water and eventually sink.
Does a piece of glass float?
No, glass sinks in water because it is denser than water. The density of glass is higher than that of water, causing it to sink rather than float.
Could glass float on salt water?
no
Can we use float cullet in container glass?
Cullets doesn't float on water.
Would a glass and wood block float in water?
if it was a cubick foot of water and the glass was the same and weighs less then the water than yes
Why do ice cubes always float a the top of the glass of water?
Ice is less dense than water and will float on water.
Do straw float in a glass of water?
Yes, plastic drinking straws will float in water.
Does a glass float or sink in water?
It depends on the shape of the fork and the material from which it is made. Most non-metal (wood, plastic) forks will float. Metal forks will sink unless they are shaped to have a large enough surface area on the bottom.
Suppose you put a birthday caddle in a glass of water why will the caddle float on top of the water?
It will float on top because it is less dense than water.
Why can a sewing needle can float on the surface of water in glass?
Surface tension
Why does a piece of glass float in mercury but sinks in water?
Glass floats in mercury because mercury is much denser than glass, creating a buoyant force that allows the glass to float. In contrast, water is less dense than glass, causing the glass to sink due to its higher density. The buoyant force in water is not enough to support the heavier glass object.
Who invented float glass?
Float glass was first invented by a company in England called Pilkington Glass.
How can you tell the difference between Black Onyx and Jet or even glass?
to tell the diffence, float both in a glass of water. The jet will float, the heavier, glass, will sink. Also Jet is soft, easily carved but easily damaged.
