I finally got back to experimenting with encaustic painting. Knowing that I needed to improve my ventilation for safety, I started reading and found a good article from R & F Paints that describes a simple way to ventilate your studio and different kinds of ventilation. For their full article on studio ventilation go to their link: R & F Encaustic Technical Sheets Then click on "Venting Your Studio for Encaustics" which will take you to a pdf file.
Their recommendation for placement of two fans is the one I am starting with now. When winter comes, I may need to buy an exhaust fan with louvers to keep cold air out of my studio when I am not using the fan. But for now I will see how using a pair of simple box fans will work. The first fan is in the window six inches above my electric palette. On the other side of the room I placed a fan on a table to blow air over the palette which will blow the fumes into the exhaust fan and out the window. This system should also be an improvement in my studio ventilation when just working with oils and not heated wax.
