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.

Burn dung for soot

Dry the dung by plastering it on a sunny wall. Burn it in the furnace with an iron sheet set as a hood over the smoke (ours), and scrape the soot off the sheet as it builds up.

Coat and fill the globes

Coat glass flasks with a thick skin of loam (clay) and let it dry. Ram the soot in firmly, leaving two or three inches empty at the neck.

Sublime

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.

Knock out the cake

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.
