Non-toxic art supplies for children: safety
In: Manufacturing

Art Supplies for Children: Safety First

When we buy art supplies for children, the first thing we think about is safety. With this in mind we search for “nontoxic” labeled on art and craft supplies for children and easily find it! Let’s learn more what this label really means.

What “nontoxic art and craft supplies for children” mean?

All art supplies for children by retailers located in the USA and Canada must undergo through third party tested certification for toxicity. However, term “toxic” is limited by ingredients that cause “adverse chronic health effects” and “acute and/or chronic health hazard”. 

One of the most common organization that certifies products internationally is Art & Creative Materials Institute, Inc. (ACMI). Their certification split products into two categories:

  1. The AP (Approved Product) – art materials that are safe and that are certified by a medical expert to contain no materials in sufficient quantities to be toxic or injurious to people or to cause acute or chronic health problems..
  2. The CL (Cautionary Labeling) Seal – products that are certified to be properly labeled for any known health risks and with information on the safe and proper use of these materials. The CL seal is not allowed on any children’s materials.

Safety labels for art supplies ACMI

Everything sounds very good and if you look at AP label you can safely use it for children, of for yourself. We thought the same way before we realized some other things… We found AP label on paints (especially sets) containing cadmiums, cobalts, ammonia, formalin, ethylene glycol and other chemicals. If paints with some of these chemicals are to be sold in California, they may have special “warning” labelling. 

Where to find more information?

Normally, all art supplies should accompany with Manufacture’s Safety Data Sheets (MSDS), where composition and chemicals have to be disclosed. However, most manufacturers keep a list of ingredients secret and MSDS contain only general information, like “no hazard known”.  

For example, the biggest supplier of children art materials in North America, Crayola, doesn’t show ingredients at all. We even can’t tell what kind of pigments are there and what they use to prevent paints from growing mold. You can find MSDS here: https://www.crayola.ca/about-us/crayola-msds.aspx 

There are many reasons why manufacturers hide ingredients, from literally hiding something to just protecting themselves from competitors. RUSART finds this practice dishonest and as children may use paints and other supplies in many ways, including licking and painting on their skin, knowing a full list of components is very important.

Why knowing ingredients of paints IS important?

Nontoxic is not always nontoxic

First of all, term “toxic” is much broader than standards determine. Even ASTM D-4236, the standard practice of labeling art materials for chronic health hazards, is saying that “1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.” 

That means, even if you see a label “conformed to ASTM D-4236”, you and yourself are in charge of use of the product. That’s your responsibility if something goes wrong.

Misuse can occur

Secondly, all art and craft paints are assumed to be used properly. So, paints – for painting on paper (or other listed support), pencils – for drawing and paper etc. But what if your child accidentally ingests paints? And that’s a very common paint “misuse”.

A lot of paints for children contain dextrin and corn starch as a filler, so paints may taste yummy for them to lick. As a white colour or as a filler companies use titanium or zinc oxides. Titanium oxide is quite safe chemical (read more in our knowledge base), but zinc oxide when ingested may cause some unwanted effects.

Cadmiums and cobalts usually are not an issue for kids paints for economical reasons. These pigments are so expensive, that manufactures would never use them for children.

Hidden chemicals

Another big issue is formalin, which is a very commonly used preservative in paints. In some countries, such as EU and Russia, it’s legally prohibited to use it in paint-manufacturing. But it’s not prohibited to sell paints containing formalin. That’s why, when you buy non-toxic paints from China, no one can guarantee they have no formalin. Similar issue you can find with phthalates.

Allergies

And, what’s very important, that’s even paints come out absolutely non-toxic, they still can cause allergies. And knowing a list of ingredients helps a lot. Paints for children may contain wheat, honey, and other allergens. These ingredients are essential for natural paints but should be avoided with those who has certain allergies.

Conclusion

  • Non-toxic label doesn’t guarantee that a products is really “non-toxic”
  • Check with MSDS
  • Choose art materials that disclose lists of ingredients
  • Stay informed with RUSART Newsletter

Rosa Gallery Oil Paints: Unique Paints from Ukraine

You can find Rosa Gallery oil paints in Canada at our RUSART shop only. Let’s see what’s interesting bout these paints and why you should take a look at them.

How Rosa paints were formulated

Rosa Gallery oil paints are quite a new product. When ROSA formulators were working on selection of colours and their performance, they decided to collaborate with professional artists. They were preparing samples of different colours with different pigment load and combination of pigments and gave them to artists for “blind testing”. Artist were choosing colours based on a better performance and other characteristics. And these choices formed ROSA Gallery palette.

Special Binder: Linseed Stand Oil

ROSA Gallery oils paints have linseed polymerized stand oil as a binder. Stand oil here is close to liquid honey by texture and colour. Benefits of stand oil is shorter drying time, thicker texture and higher viscosity. Once dry paints have moderate glossy finish. We see ROSA Gallery oil colours perfect for all prima techniques, when you paint and finish your painting within one round.

Read more about oil use in our other articles: How to choose linseed oil for painting?

Pigments Used

ROSA Gallery Paints contain both orga­nic and inorganic finely ground pigments. Combi­ning carefully selected pigments with polymerized linseed oil they obtain pure bright colour with natural look. Cobalts and Cadmiums here are hue. Rosa oil paints are manufactured in Ukraine. So, pigments there are different from what artists use in North America. That’s why ROSA Gallery oil paints can become a good complement to any modern artist’s palette.

Signature Colours

There are few special colours in ROSA Gallery palette that were formulated by artists from scratch. One of them is Flame Orange by Petro Bevza. This orange is so pure and so intense that makes it work perfectly for glazing and final touches.

Serhiy Savchenko is creator of another very beautiful colour – Azure Black. It makes very unique hues and shades. Definitely worth to try.

Based on different tests that RUSART team and supporters performed, we categorizes ROSA Gallery oil paints as artist grade. Just reminding that we have 4 categories:

  • Children (high-quality paints for young artists with no harsh chemicals)
  • Casual or Studio (budget student grade paints that a less expensive, but have lower performance or light fastness. These products can be interesting even for professional artists for underpainting, rough sketching etc.)
  • Fine or Artist (high-quality artists’ paints and other supplies for every-day painting)
  • Professional (top quality supplies that any professional artist can rely on)

How to choose linseed oil for painting?

How to choose oil for painting is the most common question for artists, both beginners and professionals. Trying and choosing right materials determine how long your painting is going to “live” and your painting experience.

What artists are looking for in oil?

When I start talking about oil as a binder for arts, I’m getting many questions from why not to use cooking oil for painting to why oil costs so different in stores. That’s a very broad questions and I’ll give all the answers in this and other articles. But let’s begin with the beginning – what are we looking for in “ideal oil”. This concept will help us choose the best oil for painting.

What would be an “ideal” best oil for painting?

  1. Ideal oil should dry fast – you want to continue layering as soon as possible while your inspiration is still with you. You don’t want to wait for a week or longer
  2. Ideal oil should be thin – you’re using oil as a thinner for your paints. If you need to change oil texture in any other ways, there are other mediums for that.
  3. Perfect oil doesn’t yellow with time – you want to make sure that your work will remain as you painted as long as possible.
  4. The best oil for painting is not reversible – that means that after drying it’s stable and permanent and will not melt and turn back to a semi-liquid form under different temperature or humidity conditions.
  5. Ideal oil provides good adhesion – layers of paint should stick to canvas or other support and to previous layers without a risk of peeling off.
  6. Perfect oil for painting doesn’t form cracking – of course, you don’t want your painting to get cracklings. If you want this “antiqued look”, there are some special mediums for that.
  7. Ideal oil has matte finish – that’s not about tastes, that’s about practical aspect. Glossy finish is fine when you work in “alla prima” techniques, i.e. paint wet-on-wet with 1 single layer. In this case selection of mediums may be broader. However, if you work in multi-layering technique, only final layer should have gloss as glossy layers do not “glue” to each other. In other words, whatever we paint on top of glossy layer sooner or later will peel off. And “later” here is less than 5 years.
  8. Ideal oil doesn’t contain toxic chemicals – if you’re sensitive to solvents and other chemicals or work in a small space with poor ventilation, you may prefer a safer options.

We hope all these help you choose the best oil for painting. Of course, “ideal oil” doesn’t exist, but we can try to get closer to this ambitious goal.

Why refined, bleached and thickened linseed oil?

Why I chose linseed oil for painting you can read in our other articles. They explain benefits of each kinds of oil. Let’s assume that we’ve chosen linseed oil and let’s find out the processing methods that make the goals of “ideal oil” real.

  1. Drying time

    Initially, extracted oil has many components inside, from different acids and vitamins to proteins. All they are good for our health when consumed, but do not work well for painting. Some raw oil components make oil sticky, increase drying time and show low transparency. That’s why cooking oil doesn’t work for painting. It simply has a goal to provide our body with nutritions, which should be removed in painting purposes. So, the first thing to choose in oil for painting is the indication “refined”.

  2. Consistence

    Most oils that just extracted have thicker texture than desired for painting. That’s why oil needs to be refined.

  3. Yellowing / non-yellowing

    Most oils for painting have yellow colour and due to some acids that linseed oil contains this kind of oil yellows with time on your painting. That’s why bleaching is a necessary process, which can be done naturally or chemically.

  4.  Adhesion

    For a better adhesion linseed oil should be thickened. In can be done in different ways or their combinations. Normally, this includes temperature and air or vacuum conditions.

  5. Ideal oil is not reversible

    The best oil for painting should stay stable and permanent after drying, meaning the oil will not melt and turn back to a semi-liquid form under different temperature or humidity conditions.

  6. Matt finish and permanency

    Due to linseed oil key characteristics, if it’s not stand oil or if there are no resins added, linseed oil provides matte finish and non-reversible.

  7. Toxicity

    Refining, thickening and bleaching takes long time. And, of course, manufacturers want to speed up to gain greater profits. And there are many technical and chemical methods to do so. Some producers are “cheating” adding solvents or turpentine in oil to make it look more transparent and reduce drying time. However, some chemicals may cause headaches and other health issues for sensitive people. Also, turpentine and white spirits, for example, require a good ventilation to use.

How Elena’s Signature oil made?

Elena Nahum Leroy (Perelman), the only owner of RUSART, recreated naturally treated linseed oil recipes that artists were using in Russia throughout generations, until the new mass-production era began. Read what she’s saying about oils.

Elena used traditional recipes that artists were using for most precious works in Russia. Yes, it took almost a year to produce a batch, but it definitely worth it.

  1. Raw cold-pressed linseed oil was naturally refined 3-5 times with water to remove protein and slime. We have to say, it took 2-3 weeks depending on quality of initial oil. And we drained about 20% of oil by volume. It’s not because the oil was “bad”, it’s because the oil has tons of stuff good as food or for wood-working purposes, but not for painting.
  2. Then we slowly heated the oil for 15-20 hours to remove water residue, polymerize and thicken. It’s a very delicate process as if a temperature is too low nothing is going to happen, and if it’s too high, oil will boil and obtain amber colour.
  3. Then we filtered the oil  2-3 times to finish refining and remove residue of sediments.
  4. And the last step – we exposed the oil to the sun for 9-12 months for bleaching.

So, we used no harsh chemicals, just power or water and the sun. That is a traditional Russian recipe of oil preparation for painting used for hundreds years.

Artist oil paints by Gamblin at RUSART

Gamblin is a dedicated manufacturer of oil paints based in Portland, Oregon (USA). Their conservation colors have been used to restore some of the most revered oil paintings in the world – including a Van Eyck at the National Gallery in London – one of the earliest oil paintings ever made – as well as notable works by da Vinci, Van Gogh, and Monet.

In Gamblin paints the manufacturer uses different binders depending on colour and pigment used. What about pigment, the other crucial component of paints, they are always in search of better and innovative options available. Let’s look at pigments they use.

Yellow colours in Gamblin artist oil paints

Although, cadmium yellow is the most beneficial yellow due to its brilliancy and opacity, you can also consider the modern and more transparent yellows – hansa yellows. They are organic pigments that are semi-transparent and lightfast. Hansa yellows retain their intensity in tints and make beautiful glazes. Also, hansa  can boost cadmiums in mixes. Also, hansa yellows make more intense and cleaner secondaries, when mixed with other organic (modern) colors like Phthalo Blue or Green.

For glazing techniques Gamblin offers Indian yellow (hue). Its transparency and a glowing warm yellow bring some amber shine to your painting.

Orange colours in Gamblin artist oil paints

Even though all we know that yellow and red make orange, mono pigmented paint are always preferable over mixed colours, because one pigment means cleaner mixing and more predictable results. Here, you can find transparent orange colours, such as Mars Orange, for glazing techniques, as well as opaque strong orange, such as Cadmium Orange.

Red colours in Gamblin artist oil paints

When we talk about red colours, we usually mean cadmiums (opaque), napthol and perinone (semi-transparent), or quinacridones (transparent). Gamblin has them all.

One of the beautiful reds is also vermillion, which is mixture of sulfur and mercury. The resulting bright, opaque red was a marvel short of philosophy but a delight to painters for a thousand years. The earth red and vermillion colors were prepared by Robert Gamblin for a Smithsonian Institute research project and are NOT available from Gamblin Artists Colors, as well as Alizarine colours.

Violet colours in Gamblin artist oil paints

Violet pigment is very rare and expensive to find, thats why painters used to mix violet colours and as a result violet and purple shades faded with time. If you still prefer mixing over single-pigment colour, try Gamblin’s alizarin permanent for mixing with ultramarine blue. Or consider making violets with quinacridone or magenta, which will make a permanent purple.

Blues colours in Gamblin artist oil paints

Gamblin blue colours include the full range of blue shades and temperature: from indanthrone, cobalt, and phthalo blue  to ultramarine Blue and turquoise blue.

Greens colours in Gamblin artist oil paints

Green is a secondary colour and as well as for purple and orange. So, green can be made by mixing colours or by using mono-pigment colours. In Gamblin you can find both options and you can choose anything from transparent phthalo green and opaque cobalts.

Earthy colours in Gamblin artist oil paints

Earthy, or brown, colours are the oldest pigments that painters all over the world used for centuries. And there is a strong reason for that. Earth colours are quite easy to extract and they have the highest lightfastness.

The late 20th century has produced the first significant change in iron oxides with the invention of transparent Mars. These colors are made by hydrating earth colors, a process by which opaque colors are made transparent.

Black and grey colours in Gamblin artist oil paints

Artists are controversial about making greys. While some artists prefer to use black as is, the others think that greys made from black are lifeless, so they remove black colour their palettes.

While overusing black in a painting will make it look dirty, neutral greys made from black and white are the same as neutral greys made from exact complements. Greys made from complements are more lively because they are incomplete mixtures of one color next to another. So come back to black with Gamblin Chromatic Black, a neutral, tinting black made from complementary colors.

An interesting alternative to mixing with white, the Portland Greys quickly lower the intensity of a color without changing its Munsell value.

Black and grey colours in Gamblin artist oil paints

White colours are core in any artist palette. Between 1/2 and 3/4 of the paint on most oil paintings is white, so the white color holds most paintings together.

Gamblin Radiant White, the most buttery white, and Titanium White have the highest tinting strength. Excellent for direct painting styles, they make the brightest, most opaque tints.

The Flake White Replacement project evolved from a prominent artist’s request for Lead (Flake) White, which had been the only white pigment commonly available until titanium dioxide was produced in 1920. Not surprisingly, the artist wanted Flake White’s working properties without the lead. Challenged, Robert tested all the Flake White oil colors on the market and found tremendous differences among them.
