The blue solid left in the dish could be a chemical compound or residue from the food or drink that was in the dish. If you provide more context or information, I could help further identify it.
liquid not solid or gas
The substance left in a dish after evaporation is known as the residue.
solid liquid
If all the water evaporated, what was left in the dish would be the solutes that were dissolved in the water, such as salts or sugars. These solutes do not evaporate with the water and remain behind in the dish once the water has all evaporated.
The blue flame typically does not leave any visible residue on the porcelain dish after heating, as it burns cleanly. However, if the flame is too hot, it may cause thermal shock and potentially damage the porcelain dish. It is important to control the heat source and temperature when using a porcelain dish.
When left in a dish, copper sulfate may slowly dry out and form solid crystals as the water evaporates. Over time, the color of the crystals may darken as the copper sulfate undergoes oxidation.
u would get a blue waffle
Most dish soaps are in liquid form. However, there are some solid dish soap bars available on the market as well.
liquid not solid or gas
To obtain a salt solution from what is left in a dish, add water to the dish and stir to dissolve the remaining salt. Filtering the solution can help separate any solid particles from the salt solution. You can then collect the filtered salt solution for use.

If blue copper sulfate is left in a dish with a lid on for 2 days, it will likely remain unchanged. Copper sulfate is a stable compound that does not readily decompose under normal conditions. However, any moisture present may cause the compound to slightly dissolve or form small crystals on the container's sides.
Nothing is "solid"; there are always holes, gaps in matter. An object APPEARS solid when the wavelength of the radiation used is longer than the size of the gaps or holes. The radio waves that radio telescopes use are several millimeters long, and the mesh in a radio telescope dish is smaller than that - so to a radio wave, the dish looks solid.
Residue on evaporation refers to the solid material left behind after a liquid has been evaporated. It can consist of impurities, salts, minerals, or other substances that were dissolved in the liquid. Residues are often analyzed to determine the composition of the original liquid.
An evaporating dish is used to evaporate liquids from a solution, leaving behind the solid solute. This is often done to concentrate a solution or to isolate a solid compound. The dish is heated gently to speed up the evaporation process.
It entirely depends on what the blue solid is! If it's copper sulfate, the solid dissolves. If it's lapis lazuli, the solid sinks to the bottom. If it's small pieces of blue fibreglass, it will probably float.
It is a blue crystalline solid
