Liquid glass is sodium metasilicate, Na2SiO3. (Wikipedia)

The "wetting" that happens when an object is immersed in a liquid depends on the surface energy of the object and the capilary forces in action on the surface of the liquid. for example mercury will not "wet" glass but water can wet the same glass.
Hey! The reason it seems to disappear is because of the refraction and absorption of light and colour. When light enters the colourless liquid, colour is obviously absorbed. The light waves refract ("bounce") off the glass test tube and leave the glass beaker (containing the colourless liquid). Because the liquid and solid are the same colour, it creates the illusion of the test tube disappearing.
Because the surface temperature of the glass gets colder than the dewpoint temperature of the air. Therefore the relative humidity goes over 100% on the glass causing water vapor in the air to condense into liquid water on the glass.
When water vapor in the air becomes liquid, it's called condensation. Many people see condensation when carrying a cold glass outside on a hot day. The condensation process creates clouds in the atmosphere.

A so-called "glass" thermometer has a small bore-hole in the center of the glass that has some liquid in it. It's the activity of the liquid in the narrow hole that makes the thermometer a thermometer.
Glass is not a liquid. It is in fact a solid.
The definition of glass is a super cooled liquid. Any liquid that is super cooled takes on the properties of glass. Glass as you think of it is just super cooled silica. What happens is that it is cooled so quickly that it doesn't actually undergo a phase change back to a solid. In reality glass is just an incredibly slow moving liquid.
It's commonly called water glass or liquid glass.
The water that forms on the outside of a glass of [ice] water is called condensation. It occurs because the surface of the glass is colder than the air surrounding the glass, which causes the water vapor in the air to cool and condense into a liquid on the outside of the glass.
It's called "condensation"...The glass gets colder than the dewpoint temperature of the air (temperature at which saturation occurs and water vapor turns into liquid water) and therefore water drops form on the cold glass.

The hot liquid could crack a cold glass.
A liquid-in-glass thermometer is a type of thermometer that consists of a glass tube filled with a liquid, typically mercury or alcohol, which expands or contracts with changes in temperature. The level of the liquid in the tube corresponds to the temperature, allowing for temperature measurement.
When a material changes from a solid to a liquid, its particles have higher kinetic energy, leading to a higher thermal energy. In the case of glass transitioning from a solid bowl to a liquid state, the particles in the liquid glass have more freedom to move and vibrate, increasing their thermal energy compared to the solid state.
No, glass is not technically a liquid. It is an amorphous solid, which means it has a disordered atomic structure similar to a liquid but is still considered a solid.
