One of the delights of browsing among old books is the possibility, the expectation even, that something curious and interesting will turn up. I recently picked up an attractive vintage book at my library book sale which both picqued my curiosity and was full of odd and interesting information
More than I actually want to know about the opportunities, challenges, hazards, and rewards of operating a commercial laundry business but fascinating to browse. My favorite entry describes the unusual technique for bleaching linen devised by a clever Frenchman who must have reaped a great return in advertising value whether or not his method was effective.
OZONIZED LINEN
An enterprising Parisian laundry company bleaches linen by balloon. A few hundred feet up the air is nearly as pure as in the open country, and it is in this ozonized air that the linen is dried by the aid of a captive balloon. The linen is attached to bamboo frames, and being rough-dried while taking its aerial voyage, a considerable quantity is taken at each ascension. There are about six ascents during the day, and an extra charge of from five to fify centimes is made for each article thus treated.
