[120] Soda-lime is made by dissolving 100 grams of "soda" in water, and carefully slaking 200 grams of lime with it. Evaporate to dryness in an iron dish and ignite at a low red heat in a crucible. Use the small lumps.
[121] Made by diluting 1 part by measure of saturated lime-water up to 10 with recently boiled distilled water.
