Cyanotype on Bioplastic

Have been experimenting with cyanotype on bioplastic. The bioplastic is made of agar agar, cornstarch and water. I am mixing the cyanotype emulsion directly into the bioplastic and coating glass sheets. In the following examples, the yellow tint is from insufficient washing because the emulsion was thick in that area. A longer wash combined with better coating technique seems to have solved the problem.
