2. Melt and pour - Wikipedia

   en.wikipedia.org/wiki/Melt_and_pour

   As with the rebatching method, it can be considered a misnomer to refer to the melt and pour process as soap making. The process has much in common with candle making using meltable wax which, using a similar process, can be scented, dyed, and shaped on a small or large scale of production. Other processes used by soapers are cold process, hot ...

3. Saltwater soap - Wikipedia

   en.wikipedia.org/wiki/Saltwater_soap

   Saltwater soap, also called sailors' soap, is a potassium-based soap for use with seawater. Inexpensive common commercial soap will not lather or dissolve in seawater due to high levels of sodium chloride in the water. Similarly, common soap does not work as well as potassium-based soap in hard water where calcium replaces the sodium, making ...

4. Saponification - Wikipedia

   en.wikipedia.org/wiki/Saponification

   Saponification is a process of cleaving esters into carboxylate salts and alcohols by the action of aqueous alkali. Typically aqueous sodium hydroxide solutions are used. [1] [2] It is an important type of alkaline hydrolysis. When the carboxylate is long chain, its salt is called a soap. The saponification of ethyl acetate gives sodium acetate ...

5. The Easy Way to Melt Ice You Never Knew About (It’s Not Salt!)

   While there are plenty of clever uses for salt, including fixing slippery surfaces, rock salt isn’t always easy to find once temperatures drop lower than the melting point of ice (32°F or 0°C).

7. Molten salt - Wikipedia

   en.wikipedia.org/wiki/Molten_salt

   Cyanide and chloride salt mixtures are used for surface modification of alloys such as carburizing and nitrocarburizing of steel. Cryolite (a fluoride salt) is used as a solvent for aluminium oxide in the production of aluminium in the Hall-Héroult process. Fluoride, chloride, and hydroxide salts can be used as solvents in pyroprocessing of ...

8. Salting out - Wikipedia

   en.wikipedia.org/wiki/Salting_out

   This process is known as salting out. [citation needed] Soaps are easily precipitated by concentrated salt solution, the metal ion in the salt reacts with the fatty acids forming back the soap and glycerin (glycerol). To separate glycerin from the soap, the pasty boiling mass is treated with brine (NaCl solution).

9. Brine rejection - Wikipedia

   en.wikipedia.org/wiki/Brine_rejection

   Brine rejection is a process that occurs when salty water freezes. The salts do not fit in the crystal structure of water ice, so the salt is expelled. Since the oceans are salty, this process is important in nature. Salt rejected by the forming sea ice drains into the surrounding seawater, creating saltier, denser brine.
