TO PREPARE SALÆRATUS.
528. Put the salæratus in a vessel, add enough cold water to dissolve it, then pour off the liquid into a bottle and cork it. Be careful to pour it off gently as a great deal of sediment settles at the bottom of the vessel in which it is dissolved.
Carbonate of ammonia is much nicer than salæratus; it is prepared in the same manner; be careful to keep the bottle corked, and keep it in a cool place.
It may be used in all the receipts where salæratus is directed; but only half the quantity is necessary—thus: if one table spoonful of the salæratus is required, half a table spoonful of ammonia will be sufficient.
