I’ve used quite a lot of starch paste during the past few months. I’m working on a book repair project and it goes not as fast as I’d like it to. However, I that gave me a chance to experiment with different sorts of paste and to make the following video.
To sum up the video: take 4-8 parts of water and 1 part of starch; mix thoroughly; repeatedly put the mix into a microwave (starting with 30-60 second rounds); mix between the rounds; wait until it starts to boil over and changes how it looks from milky condition to a glossy condition.
I’d be glad if you would share your own experience with starch paste in the comments section below!
