“masonry is the most durable material that man can use and the only material admissable in buildings of monumental character”
” Very few people realize that the fact that the common and most abundant materials for masonry construction are the most convenient, cheapest and proper in the end for building purposes”

An article on DIY ART SUPPLIES – I am all about Artists helping artists and art supplies really do not have to be expensive to be of great quality. And we all love the process of creating but lets face it making art is an investment of money, time, sweat and tears that needs to be economical to be cost effective.
Art supplies are expensive and most artists purchase their materials at high retail prices. Most businesses buy wholesale or in bulk but visual artists do not have the luxury of the wholesale marketplace. Generally we find our source of materials expensive and in an art supply store that generally serves the hobbyist.

Finding ourselves in the business of art but the cost analysis often becomes paralyzing reconciling ourselves to create what we can afford.

Therefore, we need to find materials and methods to create, test, practice and experiment without these heavy costs – especially for art students.

Here is a great article that I found and thought deserved to be Re-posted. I could not of said it better myself -especially the part about Walmart – Please do not shop there.

So, the Carnival of Pen and Paper is an ongoing series of… well, of pen and paper articles. It’s super-nerdy, and it’s hosted by a different super-nerdy blog every month. This past month, hosted at Daydreamers Welcome, JoniB departed from the typical nerditude for her “Editor’s Pick” choice, and featured an article by Caitlin Burns called 10 Money-Saving Tips for Starving Artists.

I really enjoyed reading an article with a more accessible subject– so much, in fact, that I wanted to assemble my own version. Caitlin Burns’ article had some great ideas, but I want to elaborate some new suggestions and guidelines that incorporate this blog’s specific focus on rurality, art, and technology… and, you know the topic-drill by now. So here are my guidelines, to be customized as you see fit.

1. Don’t be picky.

I’m right there with Caitlin on this first tip: don’t ever think…

Exploring Conte Crayons – Experimental Recipe for Fine artists and Clay artists

Conte crayons, paper & clay slabs

Exploring Conte Crayons 


Although most of us have explored the pastel/crayon/chalk aisle of the local art supply center, we might not have had experience with conte crayons or conte pencils. And few know any history or application of these wonderfully versatile and stable materials.

First invented over 250 years ago to supplement the softer pastel sticks being made and to offer a less fragile end product, the conte crayons of today are made of highly refined materials. Kaolin clay (a product fine enough to be used in quality cosmetics) and pure pigments are compacted to create an extraordinarily rich and smooth graphic material. These crayons are harder and thinner (approximately 1/4″ by about 2½”) than traditional pastels but offer a product that is ideally suited for drawing and sketching on a wide variety of surfaces. They can be blended with paper stumps and removed with a kneaded eraser.

Adored by portrait artists because they hold their edge and can be “pointed” for extremely fine detail work, conte crayons are the perfect addition to any artist’s sketch box. Able to overlay traditional pastel and other graphic media, they are often used to make corrections or to add detail to works in progress. Several color assortments are also available in pencil form. Because of their hardness, conte pastel pencils are premier tools for controlled detail work.


Conte Crayons for Fine Artists

Although I am still in the development stage of this recipe I am including it for artists who may wish to experiment further with this process. I have been very excited about my research so far and the quality of marks that I have been getting with my conte crayons on paper. Artist may be aware of their process in creating their art but tend to buy products ready made. Although this is convenient and for many sufficient there is restrictions to every medium and material. If you create your own art supplies you can alter the ingredients and process which will  allow more freedom in your materials and mediums. Your art supplies will work for you rather than against you.  Artist materials are generally a mixture which includes— a pigment (colorant), binding agent and strengthening material and a process (mixing, baking etc). The binding materials are generally wax, gum solution, plaster of paris, cornstarch, and fine clay (kaolin and ball clay mixture). For this recipe I have chosen to use fine clay as a binding agent for its transluscent, water soluble and color qualities.

Not to mention it is historically a favourite of many of the masters and was developed originally by Francois Jean Conte in the 1795 as a replacement for graphite.

Conté, also known as Conté sticks or Conté crayons, are a drawing medium composed of compressed powdered graphite or charcoal mixed with a wax or clay base, square in cross-section. They were invented in 1795 by Nicolas-Jacques Conté, who created the combination of clay and graphite in response to the shortage of graphite caused by the Napoleonic Wars (the British naval blockade of France prevented import). Conté crayons had the advantage of being cost-effective to produce, and easy to manufacture in controlled grades of hardness. They are now manufactured using natural pigments (iron oxidescarbon blacktitanium dioxide), clay (kaolin), and a binder (cellulose ether).[1]

Conte Crayon recipe is as follows:

100 grams ball clay
[or you may experiment with a mixture of kaolin & ball clay]
3 grams macaloid

[ OR 5 grams bentonite]

up to 25% pigment depending on strength of color desired.


Mix dry ingredients in a small container. Add a very small amount of water until the mixture is a dry oatmeal texture. Pour onto a piece of wax paper and knead into a ball. If it requires more liquid use a spray bottle on fine mist and continue to knead until it holds together well. You can roll the mixture into any shape or use a rolling pin and cut the mixture into long thin squares or roll out into long rounded shapes. Cut into lengths desired. Bake at 450 degrees for 10 minutes for soft crayons for harder crayons bake for 20 minutes on a metal cookie sheet lined with aluminum foil. If you prefer a very soft crayon let dry without baking in the oven. Conte crayons can be sharpened with a good quality pencil sharpener. Save the shavings to experiment with painting and washes.

Such as Mason stains, wedgewood blue is very popular as well as Yellow ochre & red iron oxide stains are used to achieve the sanguine colors

Pigments may be mixed for color variations.

The conte crayons are also water soluble for washes.

(All of these ingredients can be found at a local pottery supply store).

For Charcoal Black Conte: 

50 grams ball clay

3grams macaloid or 5 grams bentonite
1 tsp Black Stain (non toxic)

20 grams charcoal powder

follow mixing instructions as above – still in the development stage but you can alter the ingredients to suit your specific requirements for your artwork.

I was very pleased with how the homemade conte flowed on the paper and smudged – when applied to the paper it smudged, erased and adhered very well to different types of paper. The conte also was water soluble and behaved like watercolor paint making beautiful washes.  I have yet to add gum solution to see how that would effect the pigment as a medium.

Conte Crayons For Ceramic Artists : Use to draw on Bisque claywork prior to glaze application and firing in a kiln.
