Answer: A clockwork, fan-cooled helmet

An Imp called Peltier - well Maxwell had his demon... In 1834 a Roundworld physicist, Jean Peltier,discovered that by applying an electric current through two dissimilar metals, heat could be expelled at one junction and absorbed at the other. But since harnessing the lightning has not been possible on Discworld (lightning is the spears hurled by the thunder giants when they fight) it wouldn't work there.

There are Squirrel Cage fans on Roundworld, so I expect there may be some on Discworld, but that's not what was used here.

Answer: Hardcore

The incident is reported in "Feet of Clay".
Coalface was a privy cleaner and also Chrysoprase's "righthand troll", but escaped this time. Detritus was the nailer, not the nailee. Crysoprase was the employer of ... Hardcore ... who was aurally fixated on masonry.

Answer: Detritus=Splatter, Coalface=Privy Cleaner, Chrysoprase=Crime Boss, Ruby=Star

Detritus was the Splatter (like a bouncer but Trolls use more force) at the Mended Drum before he became a Watchman. ("Guards! Guards!

"Nobby: 'He's arrested Coalface the troll. You know, captain? The privy cleaner." ("Men at Arms")

Chrysoprase was the evil Crime Boss whose henchtrolls (Coalface and Hardcore) sold Slab on the streets. 'Dey say he's a godfather in the Breccia,' said Cliff.'Now now, that's never been proved ...'

Ruby was the singing star in "Moving Pictures." Her songs include "Amber and Jasper" and "Vunce again I am fallink in luf".

Answer: Chloric ammonium with radium

Slab is Roundworld slang for Crack (cocaine); however, cocaine isn't an ingredient of Discworld Slab, although it was once was an ingredient of Roundworld Coke. Ammonium Sulfate, which is foul smelling but harmless, was put in to Coke MagiCans so buyers couldn't tell which cans had prizes before opening them. Which sounds like something a deranged Discworld mind might have come up with - but isn't!

Molten sulphur on Coke with phosphoric acid (with an umbrella in it) is what Detritus drinks at the Bucket. Coke has phosphoric acid in it already but I expect Detritus likes extra.

Caffeine and carbonic acid are ingredients of Coke but not of Slab.

Detritus: "It are chloric ammonium an' radium mixed up. It give your head a tingle but melts troll brains." ("Feet of Clay") And it's not found in Coke.
