The rice has to be boiled in plenty of water for a whole day.
Rice is heated and poured through a sieve to retain the liquid, which is used as a glue. Boro salts are added to the glue in order to prevent decay, mold, and pests when mixed with shredded paper. When the glue is ready it is used for [Paper Brick].
[Paper Brick] is constructed of rice glue and collected shredded paper. The glue from [Cooking Glue] is added together with boro salts, in relation to decay, mould and pests.
A tube is embedded in the paper brick so a wire can run through it and securely connect bricks together.
