| Encaustic, Painting | |
| Thanks to everyone who stopped by during Open Studios 2007. Your questions are perennially interesting to me. Last year’s FAQs are listed here. This year’s top question was about pigment followed closely by some concerned questions about health and safety. HOW DO YOU “DYE” YOUR BEESWAX? I HEARD ENCAUSTIC IS TOXIC. WHAT DO YOU HAVE TO SAY? • Keep your paint cool. Never heat encaustic medium above 220 degrees Fahrenheit. Above that temperature and it starts to break down into bad-to-breathe compounds (aldehydes and such). But below that temperature it stays intact. Never melt beeswax over an open flame. Untempered beeswax melts around 140 degrees. The flash point of beeswax (the point at which its vapors can burst into flame) is around 490 degrees. • Use proper ventilation. You need a source of fresh air coming into your studio and a fan to draw fumes out. Think about the way air flows through your studio. Position yourself upwind of fumes. • Educate yourself about pigments. Some pigments are scientifically proven to be toxic, even carcinogenic to humans. (Cadmium anyone?) Avoid or use with caution. I’ve banned all known carcinogens from my studio. The city of Tucson has an excellent health and safety data sheet about artists’ pigments. Read it and adapt. DO YOU TEACH? |
