The Solvay process or ammonia-soda process is the major industrial process for the production of sodium carbonate (soda ash, Na 2 CO 3 ). The ammonia-soda process was developed into its modern form by the Belgian chemist Ernest Solvay during the 1860s. The ingredients for this are readily available and inexpensive: salt brine (from inland ...

Evaluate your whole oil profile; a minimum of 14–15% each lauric plus palmitic guarantees hardness. Overcompensating with hard oils also reduces creaminess, so keep them between 25–50% total to prevent cracking issues.
