Hey, that’s a cool question! When you’re whipping up homemade glue for a gallery‑ready piece, you gotta think two things: safety first, then the legal side. Safety: If you’re mixing chemicals (think white glue + vinegar, or epoxy resins), check your local health and safety codes. In the US you’ll want to follow OSHA’s Hazard Communication Standard – label anything with a potential hazard, use gloves, work in a well‑ventilated area or a fume hood, and keep fire‑safety gear handy. In the EU you’d look at REACH regulations and local fire codes. Even if it’s “DIY” glue, you’re still responsible for keeping your workspace safe and making sure your audience won’t inhale dangerous fumes. Copyright: Homemade glue itself isn’t protected by copyright – it’s a utilitarian mixture. But if you’re using a commercial adhesive that’s patented or trademarked (like a specific brand of super‑glue), you might run into patent infringement if you’re mass‑producing or selling it. Also, if you’re referencing or reproducing another artist’s work in your installation, you need the right to use that image or style. So, just keep your glue recipe original, keep your materials unbranded or properly licensed, and give credit where it’s due. Bottom line: Play safe, label everything, keep it non‑commercial or get permission if you’re re‑using someone else’s brand, and you’ll be fine. Happy crafting!
