Karen, God loves you and so do I. But, I can't go along with this. If we are so concerned about the health of our society, teaching the proper use and handling of our tools is the way to go. Toxicity and risks abound in mostly everything that we use in and out of our work materials. Radiation exists in our surroundings. Cancer agents exists in our drinking water. The risk of fire and breathing disorders is found in our handling of solvents. Yes, lead is a hazard. But, so is all of our materials. Most are combustible. Some are poisonous. Some are irritants. Some are sharp. But, are we going to eat them, breathe them, bath in them or set them on fire?
If Gamblin is paying us to support their products, let's do it openly. Let's not scare the pants off of every person who loves to paint and draw. I believe that if we investigate Gamblin products we will find hazards associated with them as well. For instance, odorless turpentine and mineral spirits have the same amount of toxicity as the real article. Just because that you can't smell it doesn't mean that the fumes are not there.
Yes, there are hazards in art materials. Don't eat or smoke in your work area. Don't handle powdered material in a drafty area. Do keep your workshop and tools clean and orderly. Do wear goggles and masks when handling powdered material. Do ventilate your work space. Do wash your hands. Do keep the business end of brushes out of your mouth. Do keep and dispose of rags, paper towels and combustible material in the proper manner (check with your local fire and trash disposal departments).
