  2. Microcrystalline wax - Wikipedia

    en.wikipedia.org/wiki/Microcrystalline_wax

    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.

  3. Paraffin wax - Wikipedia

    en.wikipedia.org/wiki/Paraffin_wax

    Paraffin wax (or petroleum wax) is a soft colorless solid derived from petroleum, coal, or oil shale that consists of a mixture of hydrocarbon molecules containing between 20 and 40 carbon atoms. It is solid at room temperature and begins to melt above approximately 37 °C (99 °F), [ 2 ] and its boiling point is above 370 °C (698 °F). [ 2 ]

  4. Crystallization of polymers - Wikipedia

    en.wikipedia.org/wiki/Crystallization_of_polymers

    Crystallization of polymers is a process associated with partial alignment of their molecular chains. These chains fold together and form ordered regions called lamellae, which compose larger spheroidal structures named spherulites. [1] [2] Polymers can crystallize upon cooling from melting, mechanical stretching or solvent evaporation ...

    The wax crystals typically first form at the lower circumferential wall with the appearance of a whitish or milky cloud. The cloud point is the temperature just above where these crystals first appear. The test sample is first poured into a test jar to a level approximately half full. A cork carrying the test thermometer is used to close the jar.

  6. Epicuticular wax - Wikipedia

    en.wikipedia.org/wiki/Epicuticular_wax

    The epicuticular wax produced by Dudleya brittonii has the highest ultraviolet light (UV) reflectivity of any known naturally occurring biological substance. Epicuticular wax is a waxy coating which covers the outer surface of the plant cuticle in land plants. It may form a whitish film or bloom on leaves, fruits and other plant organs.

  7. Crystallization - Wikipedia

    en.wikipedia.org/wiki/Crystallization

    Crystallization is the process by which solids form, where the atoms or molecules are highly organized into a structure known as a crystal.Some ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.
