Hazards in the art world often aren’t taken very seriously. It’s hard to see artists as people who are engaged in a dangerous field. Had I not been a scientist, I too would have remained oblivious about the perils lurking in artist’s world ! It comes as no surprise that artists through history have been called by many names-geniuses, crazy, dreamers, unemployed-but rarely chemists!

There can be a lot of mystery when you go to purchase paints, especially if it’s your first time buying a particular medium.  I remember, when I first bought a pan of watercolour paint from a local art store, I was quite alarmed to find out that the  paint contained preservative of harmful nature. I started exploring alternatives to commercial paints that didn’t contain such toxic preservatives or pigments. I soon discovered that there were a couple of  handmade watercolour paint makers who provided artists with non toxic and high quality paints.  The experience of working with such handcrafted watercolour paints was quite delightful. The art of handmade watercolours piqued my interest in learning about the process.   That’s when my journey as a paint maker began! It was definitely not easy.  I did an extensive research in understanding about different kind of pigments, their chemical properties and most importantly any potential hazards associated with pigments to human health and  environment.

So, what are pigments?

By definition,  pigments are particles of coloured materials that are insoluble in water, oil and resin.  Although, when suspended in liquid binders or vehicles, it transforms into paint. The binder or  vehicle used with each pigment, as well as the size and shape of the pigment particle, determines the type of paint that i’s created.

Pigments are classified into three basic categories, that a manufacturer mayuse when creating paint: natural organic pigments, synthetic organic pigments and inorganic pigments.

Inorganic pigments: These pigments tend to be quite lightfast, they are derived from the earth, and/or manufactured from metals or minerals. These pigments have been studied for long for their long term effects (for example;  earth pigments : Raw Sienna, Burnt Umber; Cobalts, Cadmium, Titanium etc )

Organic pigments ( natural/synthetic) : These pigments are derived from plant or animal sources, or they can also be chemically synthesized ( eg, quinacridones). Natural organic pigments are  made from carbon compounds that exists in nature.

In prehistoric times, early humans found many natural organic colourants in the minerals occurring in soils and clays. Cave paintings using red- and yellow-coloured clays date from at least 15,000 B.C. As long ago as 8,000 B.C., artists in Egypt had discovered how to process animal products and vegetable matter into useful and fairly stable colourants. The pigments from plant and animal sources tend to be safe – but the colours do fade, making them “fugitive” colors.  Although, the long term effect of these colours are as such not known.

Trend of handmade watercolours paints

In recent times, there has been a phenomenal increase in the number of handmade watercolour paint makers. My research in this field till date tells me that paint labeling is probably the least interesting topic on watercolour paints … its like reading a safety tag on your mobile phones. Unfortunately, boredom leads to lack of concern, and eventually leads to ignorance, and it is this ignorance that paint manufacturers exploit through  marketing.

The crux of the problem is that paint manufacturers (including  small business owners who are  watercolour paint makers) can name a paint anything they want. The result? If the marketing name is all you rely on, it is impossible to tell what is in your paint. Knowing the safety of artist’s material is a subject of high importance and must not be overlooked.

Let’s quickly recap some of the elements we know are bad for human health: Umbers, Sienna, Mercury, Lead, Cadmium, Chromium VI. Hazardous compounds to note: Copper and Cobalt compounds. Common effects from these various substances include cancer, nerve and organ damage.

Impact of using watercolours (pigments) on the Environment and health

Some artists (including me)  strongly attend to the health or environmental impact of the materials they use, and in a few cases watercolours do present some problems.

Environmental impact occurs through mining or raw materials manufacture and the disposal of manufacturing wastes. Unfortunately, though many high quality pigments are manufactured in Europe, Japan and the USA, the environmental consequences of industrial pigment manufacture are increasingly being exported to the Third World (China and India in particular), whose environmental laws and enforcement are of a different kind. This is one reason why pigments can be made there so cheaply and  just remember its a hell on the health of factory workers and their living environment.

Unfortunately, I know of no way at present to find out whether all pigments are manufactured in an environmentally friendly way, because (for proprietary reasons) paint manufacturers do not disclose where they buy their pigments, and there is no easy way to obtain trustworthy environmental impact statements from specific pigment manufacturers in, say, China or India. Artists or painters have no effective control over these upstream environmental impacts.

My purpose is not to frighten but to inform, so that, next time you are at checkout line at the art store or making an online purchase you can make a wise choice.

Take home message

That said, watercolours should always be handled with reasonable care and applied with appropriate techniques. They should be kept out of the reach or unsupervised use of children.

And watch out for your pets!

DISCLAIMER: This article concerns itself with the common sense safety aspects of art materials and art safety in general. The intent of this article is merely to raise individual awareness of some of the issues involved and to encourage the reader to take steps in learning more about the factors involved with the hazards associated with artist’s materials.

The art of paint making has been existing for thousands of years. Today’s paint making process is perhaps no different than how it was several 100 years ago. At the time when commercial colours were not available artists made their own paint, or had an assistant or colourman make it for them. The pigments were ground by hand on a flat piece of marble or glass using a glass muller.

Its no doubt that  making beautiful pieces of art is immensely rewarding for artists. Since we have been around paints since an early age, we don’t realize it could be dangerous in the long term. I’m sorry to remind you so: paints are mildly toxic. The  kid’s ones too are a bit toxic, most of the time. The toxic effects are due to chronic exposure.

Having a science background has helped me a lot in understanding the process of paint making, researching about a pigment, its chemical composition, properties and most importantly if there are any hazards associated with pigments that I am working with.

From pre-modern times when medical science was still ill-equipped to determine common threats, to the present day, when artists often still put their art before their well-being, certain art supplies have been a source of peril for countless painters and sculptors—and have done serious harm to some of art history’s most famous names.

Early artists were unaware of the hazards of many of the materials they used, but information on the topic is readily available today. While the long term improper use of your materials could have serious mental and physical health consequences, with proper safety precautions, awareness and common sense, these potential hazards can be mitigated if not avoided completely.

This blog post focuses on the safety precaution every artist and paint maker should take into consideration.

A few items bear repeating: Read the label. Acquire  MSDS from your supplier. Inform yourself about the pigment you are dealing with. Learn what it means. Learn what should be on the label. Choose safe materials. Use proper techniques, handling, safety gear (a must for everyone) and safety precautions. Keep you and your area clean. Use proper cleanup and disposal methods which is in sync with your city council and  environmental regulation guidelines.

All chemicals and pigment powders can be toxic if not handled correctly. Wear respirator and protective gloves and clothing. Chemicals and pigments should only be handled in strict laboratory conditions away from food, pets and children. Wash your hands thoroughly after you have finished painting or paint making.

As an artist and a paint maker I always like to work with pigments that are not only non toxic but also do not cause harm to the aquatic life. I don’t like working with handmade watercolours where the pigment classification number is not mentioned. Be informed and Be safe  … paint to your  heart’s content, as simple as that!
