There are many art fora, resource sites, blogs, and other places on the internet where information for artists is posted. This is one of them. Often, they (we?) provide contradictory information, advice, and opinions. If you are looking for reliable advice for artists, whom do you believe?
First, with regard to safety information, don’t ever just take anyone’s word for it. I have several posts here that relate to safety. But I’m just some guy. Why would you do what I say, no matter how much authority I seem to pretend to have? This is your health and the health of everyone who comes in contact with your art stuff we’re talking about here. Just because I say that lead paint, used with reasonable caution, is perfectly safe, is no reason to think it’s true. It is true, but you shouldn’t believe me just because I say so. Only believe it after you’ve checked out the relevant information, separated out the truth from the fear-mongering, and decided for yourself what makes sense for you.
I’m not an expert. I don’t have a degree in art. I’m not a professional artist. I’ve done a lot of studying about art and I think I mostly know what I’m talking about. But you haven’t read my sources. You haven’t tried the things I have. You haven’t made the mistakes, or had the successes, that I have. All you have when you come to this website is the words and images here. You don’t know for sure whether I know what I’m talking about, or I’m a clueless blowhard.
The same goes for just about everyone else. Even people who have nice websites and appear to have some sort of credentials may be providing useful information, or garbage. Likewise, people who post on internet fora may or may not know what they’re talking about. I’ve found some pretty silly stuff in books as well.
So please read with intelligence and skepticism. Do that with everything here, and everything else you see on the internet. Try people’s advice and see if it works for you. Read other sources and compare. It’s more work that way, but a lot better than deciding that I (or anyone else) can be taken at face value. I know I have a clue, but you have no reason to believe me. Not until you try what I suggest and find out.
