Studio Practice
According to my interests in different materials, I started my test and research in the printmaking studio.
Printmaking space
Dry etching on an acrylic plate
The separation process of oil and water
Air-dried ink
After my project " London Prayer Wheel ", I turned my direction to the receipt paper, I found that Thermal paper (sometimes referred to as an audit roll) is a special fine paper that is coated with a material formulated to change color when exposed to heat, furthermore, a fingernail swiped quickly across the paper will also generate enough heat from friction to produce a mark.
Air freshener, nail remover, sharp objects reacting with thermal paper
The study of thermal paper:
once the temperature has risen above 60c, the paper would be colored in a very short time. BUT it can not be reserved for a long time (maximum 10 years)
Keywords:
heat, temperature, change, temporary...

3 Dec. 2019 Tutorial with Geraint
By introducing and analyzing what I currently have done, I start to realize that I need to find a more active way to paint(to maximize the sense of freedom and romance of my project.) plus, I should find some pure chemical liquid to support my further research.
The chemical lab, Imperial College London
8 Dec. 2019, I asked my friend who studies in the chemical engineering department for help, due to this tour I have access to a variety of chemical agents and types of equipment.
Methanol on heated thermal paper
Acetone on heated thermal paper (unstable)
Isopropanol on heated thermal paper
Hydrochloric acid on heated thermal paper
(red color faded away after 3 minites)
According to those test results, I finally chose ethanol to be my paint because of the stability and safety of it.Then I let the Teflon rods(a kind of magnetic stirrer ) to be the painter, see what will happen on the thermal paper at different speeds.
