So, it's a hundred degrees out and you are sweltering. Maybe so is your artwork. If you have an encaustic piece hanging in your home you might be worried. But fear not. Unless your space hits 190 degrees your artwork will be perfectly fine. It might get a little tacky in high temps so just leave it alone. Once cooler weather prevails you might want to give it a little buffing with a soft cloth (cotton or microfiber works well). That's it. Encaustic medium is incredibly durable and will last a lifetime.
