Salt is sometimes added to glass to decrease the number of air bubbles in the mixture.
salt corrodes glass
A properties of compounds problem. Since salt dissolves in water, and glass does not you can dissolve the glass-salt mixture can then filter out the glass particles, then evaporate the salt solution, and you would get your salt. Though what I would do is buy more salt, and broken glass is never fun to play around with, even in chemistry class.
You smoke the bath salt "from" the glass tube not on it
A mixture
Yes, it does. When the water evaporates, it can not take the salt with it, so if you left a glass of salt water out, when it is evaporated the salt will be on the glass.
When salt water is poured into a glass containing cold tap water, the salt water will collect and settle at the bottom of the glass. This is due to the salinity and density of the salt water.
A mixture
a solute
Ground salt is soluble in water, glass is not. Put the mixture in a strainer and run water over it for an extended period. Water. The salt dissolves, the glass doesn't.
Glass
no
Sea glass is a type of glass that is found near salt water. It is basically just broken pieces of glass that have been weathered and tumbled in salt water. The pieces then become smooth and cloudy over time.
