Why can't a metal mug containing very hot tea be held comfortably while a porcelain cup can be?
The metal of the mug is a better conductor of heat than the porcelain cup, which has a porous interior. This means that the tea in the cup will lose its heat more slowly than in a metal mug. The lower specific heat of the porcelain also means that the heat energy it does absorb from the liquid will not be as great, and can be dissipated more readily by the skin.
Most metal cups will have two layers with foam or airspace between the inner and outer layers.

What does substrate mean in porcelain crown?
In the context of porcelain crowns, a substrate refers to the underlying material or structure to which the porcelain is applied. This substrate is typically made of metal, such as gold or a non-precious alloy, or it can be a ceramic material. The substrate provides strength and support for the crown, while the porcelain layer offers aesthetics and a natural appearance, mimicking the look of natural teeth. The combination ensures both durability and a pleasing visual result.

Can porcelain be melted down and reshaped?
Porcelain cannot be easily melted down and reshaped like some other materials due to its high firing temperature and crystalline structure. Once it is fired, porcelain undergoes a transformation that makes it more durable and less malleable. While it is technically possible to grind it into a powder and mix it with other materials to create a new form, this process does not result in a straightforward melting and reshaping. Therefore, traditional porcelain items cannot be remolded in the same way as materials like glass or metal.
