1. Jet is found in the cliff edges around Whitby, in Yorkshire.
First sort the jet from the sea coal and dark shale also found in the strata.
It's quite hard to tell the difference when collecting but after they've dried
for a few days the difference is more obvious.
3. Scrape remaining impurities off the surface, using a dental pick.
5. Using a jeweller's saw, a piece of jet is cut to shape.
7. Carving the surface of jet to a pattern is done with the files and blade edges
|
2. Wash the jet thoroughly, using a brush to get as much dirt off as possible
4. Tools for jet working: L-R: Jeweller's saw and blades (in a brass tube), Calipers, Archemedes drill, Dental picks, Riffer Files, Needle files, Pin vice, and Scalpels.
6. Emery paper of increasingly fine grade is used to smooth the cut surface
