2. Wax melter - Wikipedia

   en.wikipedia.org/wiki/Wax_melter

   Wax melters are devices used in the packaging and candle-making industries to melt wax. The type of tank used to melt candle wax is quite different from adhesives, solder, and tar. For example, tanks used for adhesives may need to be heated up to 260 °C (500 °F) [ 1 ] whilst an organic soy wax will be ruined at over 60 °C (140 °F) and ...

   The melted wax can be cast to make multiple copies that are further carved with details. Jewelry suppliers sell wax molded into the basic forms of rings as well as details that can be heat welded together and tubes and sheets for cutting and building the wax models. Rings may be attached to a wax "tree" so that many can be cast in one pouring.

6. Soldering - Wikipedia

   en.wikipedia.org/wiki/Soldering

   With silver soldering, small pieces of solder wire are placed onto the metal prior to heating. A flux, often made of boric acid and denatured alcohol, is used to keep the metal and solder clean and to prevent the solder from moving before it melts. When silver solder melts, it tends to flow towards the area of greatest heat.

7. Thermal expansion - Wikipedia

   en.wikipedia.org/wiki/Thermal_expansion

   A number of materials contract on heating within certain temperature ranges; this is usually called negative thermal expansion, rather than "thermal contraction".For example, the coefficient of thermal expansion of water drops to zero as it is cooled to 3.983 °C (39.169 °F) and then becomes negative below this temperature; this means that water has a maximum density at this temperature, and ...
