Porcelain contains impurities such as iron oxide that can cause it to turn brown when exposed to high temperatures. These impurities react with the oxygen in the atmosphere during firing, leading to the discoloration.
Porcelain will turn black when heated over a Bunsen burner due to carbon deposits from incomplete combustion of the gas. The carbon particles are deposited on the surface of the porcelain, causing it to appear black.
Nothing! but if you keep it in for a while, the flame turns orange
Porcelain will not turn red when subjected to a Bunsen burner flame. Instead, it will remain white and may heat up without significant visible change.
Sugar. When heated, sugar undergoes a series of chemical reactions called caramelization, which changes its color from white to light brown to dark brown to orange.
When water is heated, it can turn into steam, which is essentially water vapor.
brown
Porcelain turns black when heated due to carbon impurities in the material being burned off, leaving behind a black residue. This happens at high temperatures where the carbon particles react and create black pigments on the surface of the porcelain.

the sugar in the milk is carmelized thus turning brown.
clay heated in a kiln really hot
A common powder that turns brown when heated is flour, particularly when used in the process of making a roux or toasted for baking. The Maillard reaction, which occurs between amino acids and reducing sugars when heated, contributes to the browning effect. Additionally, cocoa powder can also turn brown and develop deeper flavors when heated.
Caramelization happens when sugars are heated until they melt and begin to turn brown. Thus foods with sugar in them (eg onions) can be heated and browned "caramelized".
Heated hot enough, which is very hot, porcelain decomposes. It is possible that the materials it forms could melt, I don't know.
Using porcelain pans on an electric stove is considered generally safe. Follow the manufacture's care suggestions and keep an eye on them Don't let them boil dry. Excessive heat can cause porcelain to melt.
Porcelain is the whitest. SwimmingFish....BROWN SERVER

No. It does not turn brown.
