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.
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.
Liquid glass is sodium metasilicate, Na2SiO3. (Wikipedia)

It depends on whether or not you are talking about a white opaque liquid.
well most things in the world start as a liquid. What most do is but in a "glass oven" it harden in the mold and you have the glass that you see today. In other words is it goes from liquid to solid. please pass your wisdom on . . . Wise woman age 9

The "nature" of it is the same as if it weren't immersed. However, if it has the same refractive index as the material it's immersed in, it will no longer have any discernable effect on the refraction of light; from the outside it will appear to just be another part of the liquid (it may well disappear from sight, since it's no longer visually distinguishable from the liquid itself).

Galileo developed the thermoscope to measure hot and cold during the Paduan period. Galileo would use a glass bottle about the size of an egg, with a long glass neck. He then heated the bottle with his hands and then immersed it partially in a vessel full of liquid. When he removed his hands, the liquid rose to a certain height in the neck, remaining above the liquid in the vessel.
Glass is not a liquid. It is in fact a solid.
Liquid glass is Sodium Silicate also known as water glass.
They can be green, yellow, brown, black, or clear/colourless.
immersed is a phychilogical experience when one object is held up by a fluid or gas. If you use the old nogan, and use the experiment wisely, and calculate the volume or gas+liquid you'll get an anser of 1.23575882810 I did it in gr.3 passed grade kindergarten, 1, 2, ,3 ,4 ,5 ,6, ,7, ,8 and made it to high school. I passed gr 11+12

Liquid glass has more thermal energy because it's really hot. A normal glass bowl isn't as hot as liquid glass.
what do they use for the liquid in glass ball thermometer
It may if it were heated, then immersed in cold water.
