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)

∙ 14y agoGlass can float. Next time you do the washing up notice how a glass plate or a glass floats. That's because glass can float on water
.. other writer..
glass cannot float. it is denser than water causing it to sink. The only reason that the writer above has realized that the glass plate has floated is because that when you place the plate on the water you catch an air pocket. and it stays afloat the surface.
thankss

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?
B/c the density of mercury is higher than that of glass, while the density of water is lower than that of water.
What is denser than water so water will float?
Anything that doesn't float in water is less dense than water, say iron? So if you drop an iron bar into a glass of water, you can say that the iron sinks or you can interpret it as the water floats? If you are referring to liquid, then mercury.
Why don't iceburgs sink?
Ice is less dense than liquid water, so it floats. This is the same reason why ice cubes float in a glass of water.
Could glass float on salt water?
no
Can we use float cullet in container glass?
Cullets doesn't float on water.
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.
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 can a sewing needle can float on the surface of water in glass?
Surface tension
Why can a sewing needle can float on the surface of water in a glass.?
Surface tension
If you poured oil into a glass of water would it sink or float?
it won't cuz
Why does a piece of glass float in mercury but sinks in water?
B/c the density of mercury is higher than that of glass, while the density of water is lower than that of water.
Who invented float glass?
Float glass was first invented by a company in England called Pilkington Glass.
