Color changing experiments on different fabrics: silk and Batist.

We will work furthermore on the silk fabric and with the aubergine-like color.

This color appears when you bathe the exposed (blue) cyanotype in diluted nitric acid, water the fabric for a while, then bleach it in Soda, water it again for about 10 min, and final step is to bathe the fabric in gallic acid.
