Sal Ammoniac Sublimed from Dung Soot, the Egyptian Way, Ure 1839
Sal ammoniac takes its name from the temple of Ammon in Egypt, where it was made from the soot of burned camel dung. Andrew Ure (1839): pack the soot into loam-coated glass globes over a furnace and heat them to a dull red; the salt rises and sets as a cake inside the top. Keep the necks clear or the globes can burst.
The picture: ammonium chloride crystals.

Set the globes in holes over the furnace flue and fire with dry dung, slowly at first, until they glow a dull red. The salt rises and cakes inside the top. Clear the necks often with an iron rod: a blocked neck can burst the globe.

When cold, the globes are usually cracked. Break the glass away from the white cake at the top with the back of a hatchet. Bruise the residue at the bottom and add it to the next charge. Store the salt in a jar.
