Both are blue in dilution. Each has a variety of uses. My interest is in how I might be able to used them to reveal what is otherwise invisible.
Methylene Blue is used as a revealing stain in biology.
Malachite Green is also used as a fabric dye. It is also used (controversially) as an antimicrobial in aquaculture.
I’m also trying out some new stamps and stamp pads. And some stencils of arrows I’ve been making. I’m using rice paper off a roll.
Do you have any ideas for revealing the invisible? I’m always open to tips and hints, new techniques and book suggestions.
