Although this series emphasizes the dangers of some materials we normally use in our crafts it is not meant to scare you away from anything you do, but rather to support the health of the environment and of course of yourself. In other words, this is not intended to be a Party Pooper!

The precautions we should take, the impact on the environment and the reproductive risks that some of these material pose should be of great concern to us.
Many artists still pour the remains of paints, solvents etc. down the drain, since that was allowed even in reputable Art Schools until quite recently.
In this new century we face enormous challenges and the best way to collaborate is by supporting each other and by taking that extra step to do what might seem a little nuisance at first (like disposing of material properly) and transforming that into second nature.
Tip: dedicate a bag or a box to put your scraps instead of tossing them in the garbage. Depending on what you do you can usually find a place dedicated to their proper disposal. Since I use paints, varnishes, epoxies, batteries and such, I take them to Lowes (or HomeDepot) which will gladly recycle them (since they also sell them!) And most communities have a hazardous waste pick-up day.
Trivia: more than 62% of disposed lead comes from batteries alone!
Since this series does not intend to be a comprehensive guide about the use of materials common to all crafts (that would take a fat book indeed) but rather create some food for thought and discussion, I will just mention some obvious ones and more importantly ask you to read the labels of the products you use and Wiki them☺ (it has now become a verb!) to learn about them.
You will find it very interesting and informative.
Most materials we use fall into these categories I call TRIC:
Toxic…………..like, GAAAAGH!
Reactive………like BOOOOM!
Ignitable……….like OOOPS!
Corrosive……...like ????!
Epoxy adhesives, which also include polyurethane, acrylic and cyanoacrylate or “crazy glue” are some of the major class of adhesives we use in crafts in general.
They have excellent structural strength and come in so many formulations that they have become a favorite in the arts as well as for industrial and even space applications. Slow and fast, flexible or rigid, transparent or opaque, they can be used in practically any material from wood to glass, metal, stone etc.(except some plastics, more on that in next installment), withstand high temperatures, and even be used under water in some cases.
Epoxy resin can also be used as a painting medium by mixing it with pigment and working on consecutive translucent layers, and of course it is widely used in jewelry.
Precisely because of these wonderful qualities, we have to be ever more careful when we work with them and take extra precautions particularly around children.
Most epoxy resins require a catalizer or “hardener” to trigger the chemical reaction.
We can easily detect the hardener by the garlic like smell. But like gas in the kitchen, the smell is an indication of something that we must deal with safely. One risk of working with epoxy resins lies in the hardener, which can induce an allergic reaction.
But what we must be very concerned about is that, the hardener contains both epichlorohydrin and bisphenol, which are building blocks of epoxy resins and are endocrine disruptors.
According to some reports* they are linked to some of these effects in humans:
• oestrogenic activity; (female sex hormone related)
• alteration of male reproductive organs;
• early puberty induction;
• shortened duration of breast feeding;
• pancreatic cancer
Needless to say, if you are pregnant avoid using these type of resins altogether.
Tip: When you work with these adhesives make sure you have some white vinegar at hand. Vinegar is an effective solvent and you can use it to clean, not only your tools, brushes etc. but your skin as well. Usually, acetone is listed as the “proper” solvent, but using acetone to clean epoxy will pass the mix into your bloodstream quite efficiently.

Trivia: a piece of cured epoxy if buried in the ground for 2000 years will show up practically undisturbed.
Note: In her excellent book “The Artist's Complete Health and Safety Guide”, the author, Monona Rossol , herself an artist and actress with a chemistry background, explains in great detail the specific hazards of materials commonly used by artist in different fields in an easy to understand language.*
