[D8822ABE], Letter from Sterling Syrup Works to Thomas Alva Edison, December 23rd, 1888

Editor's Notes

"We hear of Electric Bleaching of paper pulp, and of electric sugar refining. We are very much interested in this, as it may have an important bearing in the sorghum industry. We have tried all ways, including bone black, and sulphurous acid. Possibly ozone produced by electrical means may be the "friend" process of sugar refining, and it may perhaps be adapted to syrup refining. Sorghum cane can be had here in any quantity for #1.50 per ton, it yields 100 pounds of sugar and twelve gallons of dark molasses, or 28 gallons of colored molasses. If the objectionable color can be removed it will be a great thing for the country, and also for the manufacturers. 38,000,000 gallons of molasses were imported last year, sorghum produced 25,000,000 gallons, which would have been much more valuable if bleached to proper color. We would value your views if you care to give them." Respectfully, Sterling Syrup Works [Marginalia: "Sugar can be bleached by electricity but don't know about refining. See papers in re friend." "Ans Jan 17/89"]
