This extraction process was termed lixiviation.
SODIUM CARBONATE . The ashes were then "lixiviated" (washed with water) to form an alkali solution. Soda ash, Jmoles. , The sodium carbonate concentration in soda ash varied very widely, from 2–3 percent for the seaweed-derived form ("kelp"), to 30 percent for the best barilla produced from saltwort plants in Spain.

RISK: Sodium bicarbonate is a Generally Regarded As Safe (GRAS) chemical at levels found in consumer products, and has a low risk of toxicity in humans. Sodium carbonate is a component of many dry soap powders. The land plants (typically glassworts or saltworts) or the seaweed (typically Fucus species) were harvested, dried, and burned.

This process was developed by Chinese chemist Hou Debang in the 1930s. Sodium carbonate occurs in multiple hydrate forms (anhydrous, monohydrate, heptahydrate and decahydrate). IDENTIFICATION Product name: Sodium carbonate, anhydrous . However, it remained the major production method for sodium carbonate until the late 1880s.
Catalogs and product finders. The Solvay process quickly came to dominate sodium carbonate production worldwide.

The Chinese name of Hou's process, lianhe zhijian fa (联合制碱法), means "coupled manufacturing alkali method": Hou's process is coupled to the Haber process and offers better atom economy by eliminating the production of calcium chloride, since ammonia no longer needs to be regenerated. Using 20% of the specified amount (0.20 multiplication factor) is way off. The solution temperature is then lowered to below 10 °C.  This conversion entails two parts. Imaging flow cytometry makes it possible.
to the dried substance), BioUltra, anhydrous, ≥99.5% (calc. Sodium carbonate, 16 My notes say that if you've got anhydrous sodium carbonate and your formula calls for monohydrate, you should multiply the weight by 0.833. "Barilla" is a commercial term applied to an impure form of potash obtained from coastal plants or kelp.
Large natural deposits found in 1938, such as the one near Green River, Wyoming, have made mining more economical than industrial production in North America.
