 There are varieties of isinglass namely square and lined 

 whose difference is simply a matter of shape, not that of mate- 

 rial or method of manufacture. The principal districts in Japan 

 where isinglass is produced are the four prefectures of Osaka, 

 Kyoto, Hyogo and Nagano, in three of which both square and 

 lined isinglass are abundantly produced. 



The products from Nagano prefecture was chiefly limited to 

 the square variety but owing to the nature of the demand in 

 foreign markets the manufacturers of lined isinglass have within 

 recent years considerably increased. The process of isinglass 

 manufacturing may be divided into three steps, the bleaching of 

 the material, boiling and drying and smoking. The material 

 for the isinglass is a sea weed known as Sekkasai. The method 

 of manufacturing may be briefly stated as follows: — In the 

 winter season dried sea weeds are steeped in river water. After 

 being sufficiently cleansed and bleached they are boiled in a 

 kettle and when melted they are filtered and transferred to a 

 separate vessel where it is cut to a fixed size and prepared 

 by diying. The climate and the conditions of the land have 

 serious effects upon the preparation of this article. A rigorous 

 climate and a place free of strong winds are necessary so that 

 the best qualities are abundantly obtainable in such special districts 

 as above mentioned.
