All trimmings from the glass in cutting the discs were carefully garnered. These formed what is known as “glass cullet,” which was returned to the glass-makers. Being of high quality the cullet commanded a ready sale, the glass obtained from re-melting being used for the fabrication of ink-bottles, salt-cellars, scent-bottles and a hundred and one other articles in urgent request, while an appreciable quantity was again converted into the base for further photographic negatives. Plates exceeding the officially inscribed thickness of one-sixteenth of an inch were not unceremoniously consigned to the melting-pot, but after being stripped of the emulsion, were sold to the trade for contrivance into the _passe-partout_ photographic mounts so much the vogue to-day among enthusiastic amateur photographers, for picture framing, and numerous other applications for which their dimensions and the quality of the glass rendered them eminently suitable. Turning to another phase of industry, gloves of every description have soared in price, irrespective of the materials used in their production. Even those contrived from stout textile, which five years ago were readily procurable for a few pence, commanded shillings a pair. In this instance the rise in price was primarily due to the call for vast quantities by the munition factories to extend a measure of protection to the hands of the workers, more especially the women. Toiling Britain became converted to the gauntlet habit, so pronounced across the Atlantic, as a result of war. As may be imagined, from the character of the work involved, these gloves suffered speedy deterioration, becoming saturated with grease and grime from the handling of metal and the operation of machinery and tools. One firm found itself saddled with 112 lb. of these dirty gloves every week, and the item “glove renewals” consequently grew somewhat impressive. Feeling that this expenditure might be capable of reduction, the firm sought a simple and inexpensive cleaning process for the removal of the grease, to give the gloves a new lease of useful life, the fact having been ascertained that the textile itself suffered little injury as the result of a few days’ wear and tear. Experiments were made and the requirements of the firm were met very effectively. Not only were the gloves turned out clean and sound, enabling them to be used over and over again until the textile was worn out, but the oil and grease with which they were sodden was recovered. This was cleaned and found serviceable either as “cutting oil” for use with the tools, or as fuel oil for engines of the Diesel type.
