* A fixed alkali may be extracted from all vegetables ; but fumuierrw and 
koormwood will yield the greatest quantity, and the least; one thousand pounds 
of fumuterrte yielded about two /hundred and nineteen pounds of ashes, and seventy- 
nine of salt; the same quantity of tvormvjood ninety-seven pounds and a half of 
ashes, and seventy-three of salt ; the same quantity of Jir yielded only three pounds 
and a half of ashes, and half a pound of salt. Jrisft Royal Academy , 17 91. 
The ashes imported from Spain and Russia are said to be the purest and best, and 
when only in a fine powder, are called pulverine or barilla , but when made into 
hard lumps, are called rochetta; and M. Lavoisier (in his Elements of Chemistry) 
says that all vegetables y ield more or less salt or pot-ash, in consequence of com¬ 
bustion, which is more or less saturated with carbonic acid; but as this substance 
cannot be procured but by means of processes capable of furnishing oxygen and 
azpte, such as combustion, or by means of nitric acid; it is therefore as yet un¬ 
certain whether it previously existed already formed in the vegetable, or whether it 
be a produce from these operations.—-To obtain the salt or pot-ash, pour about a 
pound of ashes on a quart of soft hot water, which let stand for a week, frequently 
stirred ; then pour off the water, and if the ashes faste salt, pour on a little more 
water; then evaporate the water in a shallow vessel, and the salt will remain.—To 
make pure pot-ash, dissolve this salt in water, then add two or three times its 
weight of quick lime, filtrate the liquor, and evaporate it in close vessels; by this 
means it is almost entirely deprived of it^ carbonic acid, and is soluble in alfcohoL 
Pearl-ash is pot-ash refined by calcination. See note to soda, in the Index .
