Making Isinglass from the Swimming Bladder Used to Clarify Wine and Beer, to Make China
���Drying the Bladders
Sounds from hake being dried before they are converted into isinglass. The sounds are the Bwimming bladders of the fish. They regulate its weight so that it can maintain its posi- tion at whatever water level it chooses. One ton of hake will yield from 300 to 500 sounds weighing from 40 to 50 pounds.
��From Bladder to Isinglass
R(jllitiR hake sounds for isin- glass. The dried sounds an- softened by soaking them in water. They are then cut into small pieces. The material is mixed again and run between iron rollers. It is then passed through hollow, wator-coolcd rollers and comes out in Hhects. Finally the sheets arc passed through Bmall ribbon rollers.
