First, the site of the injury should be removed from the source of heat, to prevent further scalding. If the burn is at least second degree, remove any jewelry or clothing from the site, unless it is already stuck to the skin. Cool the scald for about 20 minutes with cool or lukewarm (not cold) water, such as water from a tap. [3]
Scalding is a type of thermal burn caused by boiling water and steam, commonly suffered by children. Scalds are commonly caused by accidental spilling of hot liquids, having water temperature too high for baths and showers, steam from boiling water or heated food, or getting splattered by hot cooking oil.

Note that the especially high molar values, as for paraffin, gasoline, water and ammonia, result from calculating specific heats in terms of moles of molecules. If specific heat is expressed per mole of atoms for these substances, none of the constant-volume values exceed, to any large extent, the theoretical Dulong–Petit limit of 25 J⋅mol ...

Here's how to do it: Microwave water in a glass (alternatively, boil water in a kettle, then pour into a glass). After you fill up the glass, pour it out. Then, set the hot glass over your stick ...
Frit for enamelling steel is typically an alkali borosilicate glass with a thermal expansion and glass temperature suitable for coating steel. Raw materials are smelted together between 2,100 and 2,650 °F (1,150 and 1,450 °C) into a liquid glass that is directed out of the furnace and thermal shocked with either water or steel rollers into frit.
