So here's a question for you guys - what should absolutely NEVER BE mixed due to creating hazardous gases or reactions? I know that using bleach in anything is a bad idea, but what else? I read somewhere that Rit dye shouldn't be used, and why is that? Does iodine react with anything? What shouldn't xylene be mixed with? The reason why I am asking is because I have a bunch of various inks and shit laying around and I kinda want to experiment with mixing them but I also don't want to fucking kill myself.
