Dōsa

オーダー作品のキャンバスが準備出来たので、今日はドーサ引きを行いました。ドーサとは日本画材が和紙や布の基底材にしっかり定着する様に、基底材に塗るコーティング剤の様なものです。材料はミョウバンと膠と水です。膠の主成分のタンパク質にミョウバンが架橋結合して基底材に被膜を作ります。近頃木板を基材にする事が多かったので、ドーサ引きはかなり久々でした。

The canvas for the custom-made work was ready, so I applied the Dosa on it today. Dosa is like a coating agent that is applied to a base material such as Japanese paper or cloth so that Japanese painting materials can be firmly fixed to the base material. The ingredients are alum, animal glue and water. Alum cross-links the protein, which is the main component of animal glue, to form a film on the base material. It’s been a long time to do this process since I almost used wooden board as base material recently.
