RMD96J3N–General view of an Alum works in the Whitby area. From George Walker 'The Costume of Yorkshire' Leeds 1814, Aquatint. Steeping calcined (burnt) shale in water in pits produce raw alum liquor which would be gravity fed to processing plant where it would be refined and boiled until alum crystals produced. These were important as a mordant (fixer) in textile dyeing industry.

RM2WN9JY1–Harry Potter fan James Robbins, eleven, a pupil at Craigentinny Primary School, Edinburgh, gets hold of a giant blood red crystal, like the Philosophers Stone in the Harry Potter movie which is released today, at The University of Edinburgh's Chemistry Department today, Friday 16/11/01. As part of Chemistry Week which starts today James was competing with pupils from throughout Edinburgh and The Lothians in a competition to grow crystals and leapt at the chance to get hold of the giant chrome alum crystal which the University normally keeps locked up in it's museum.

RM2AXFN9H–Scientific amusements . When clay is submitted to the influenceof sulphuric acid and chloride of pota-sium, we obtain alum, which is a sul-phate of alumina and potash. Alumis a colourless salt, which crystallizeson the surface of water in beautifuloctahedrons of striking regularity. TheCalcined alum. |^g ^^ page 21 represents a group ofalum crystals.

One drop of a saturated solution to each ounce ofdeveloper is usually sufficient to prevent abrasionmarks, and one additional drop of bromide of potassiumto each ounce should also be added, as it tends to pre-serve the color and vigor of the print. When iodide of potassium is used in the hypo-alum toning bath it should never be added except insolution. A hypo-alum bath, to which crystals of iodide havebeen added, may cause yellow stains on the prints. 11 *P o r t r a it A Useful Electric Heater With the almost universal use of the hot hypo-alum method
