Komon Nuka is defatted and finely ground rice bran (also called Rice Polish Powder). Take care not to confuse this with the regular rice bran easily found on the shelf of Asian food stores. It is an ingredient for making Nori Paste (Japanese Rice Paste Resist). Its role is to reduce the elasticity of the rice flour in order to make the nori paste easier to handle.
Mochiko is glutinous sweet rice flour. This product remains glutinous and elastic, retaining a strong adhesive quality even when boiled or steamed. It enables the nor paste to remain on the surface of the fabric and yet fill in between the warp and filling yarns.
Calx is also known as calcium hydroxide, hydrated lime, or slaked lime. It serves as an alkali in many dye recipes.
Calx is used in indigo fermentation vats and serves to raise the ph level helping to dissolve the indigo and aid in the reduction of indigo. Calcium hydroxide is also an ingredient in Nori paste (Japanese rice paste resist). It causes the starch in rice flour to swell and give the paste body. It also acts as a preservative.
