The manufactured products are use out a proportion of invert sugar. ful for various industrial purposes, and as one The solution of sodium alginate is made up example can be used for many of the purposes with glucose, glue, gelatine, agar-agar, sugar for which soft rubber is now employed.v Sheets syrup, or a cellulose compound known under the or ?lms can be made up into personal protective registered trade~mark “Cellofas.” which is a coverings against water or ‘gases.
