Fish glue （Sizing Liquid）
Dilute the liquid 4~5 times (4~5%) with water.
(Non-bleeding effect it demonstrated without adding alum so please use it by itself.)
Warm 4~5% fish glue up to 25℃〜30℃. Paint it slowly (move your brush 2cm per second) on washi paper with a flat brush. Wait for 2~3 days until the paper will be dried.
※Non-bleeding effect of the fish glue is depending on humidity, temperature, and a type of paper. Please adjust its density from the referred percentage.
(Recommend season is from Fall to spring in Japan because low humidity and low temperature are suitable for sizing.)
※This item is for sizing paper, please avoid mixing with paints.
There is a risk that paints will be cracked because the viscosity of the fish glue is high.
However, it can be used with gold powders (Kindei) and pearl pigments, please dilute the fish glue to 1~2% for mixing with those.
To use the fish glue for metal leaf application, dilute it to 1.5~3% and add sodium alginate.
