Clerkenwell is a centre of the watch-making and jeweller's industries, long established here; and the Northampton Polytechnic Institute, Northampton Square, a branch of the City Polytechnic, has a department devoted to instruction in these trades.
It's a great place to listen to the music of the dulcimer, the weaver's shuttle, the woodworker's plane, the jeweller's saw, and the potter's wheel while you enjoy shopping for your own unique gifts and treasures.
Ferric oxide is employed as a pigment, as jeweller's rouge, and for polishing metals.
