Many salts do not decompose when heated.
There is no name for it. I've checked so many websites but none of them include the top part.
he was a German chemist, and philology professor
I would say there's only the one type.
He invented many things, most commonly the Bunsen burner. See the related link for a few more things he invented.
Bunsen burners are available from many different stores and suppliers. Some stores that sell Bunsen burners include Medex Supply, Amazon, and Gorilla Scientific.
Silicon dioxide (SiO2), commonly known as quartz, does not decompose when heated with a Bunsen burner. This is because SiO2 has a very high melting point, around 1,710°C, which is above the typical temperature of a Bunsen burner flame. Instead of decomposing, it stays solid and retains its structure.
A Bunsen burner is a device used in scientific laboratories for heating, sterilization, and many other uses. The device safely burns a continuous stream of a flammable gas such as natural gas (which is principally methane) or a liquefied petroleum gas such as propane, butane, or a mixture of both.
A meeker burner is like a Bunsen burner in the fact that it uses propane as a fuel source, but there are many differences. A meeker burner burns hotter then a Bunsen burner and it also has a grid over the flame that causes the flame and heat to vibrate as the propane burns.
Robert Bunsen (1811-1899) was a German chemist, discoverer of caesium and rubidium (with Gustav Kirchhoff), is one of the inventors of the Bunsen burner (with Peter Desaga), published many contributions in other chapters of chemistry.
