Term: Binder
Definition: A substance mixed with pigment,
it holds raw pigment in such a way that it becomes workable in a painting medium. Its purpose is to weld the pigment granules into some sort of shape---liquid, semi-liquid or solid---where brush, knife or hands can carry the color to the canvas or paper. In oil paint, raw pigment is usually combined with a linseed oil binder to form a fluid paint. Watercolor's binder is gum Arabic, and pastel is bound with gum tragacanth. Joe Singer writes in his book, "How to Paint Portraits in Pastel" that 'it is often the binder and not the pigment that is the main cause for the deterioration of paintings, especially oil.' Source: Roger Dunbier, PhD, Unpublished essay on Mediums.
The nonvolatile adhesive liquid portion of a paint that attaches pigment particles and the paint film as a whole to the support.
That which holds the paint together, such as linseed oil for oil painting, polymers for acrylics, gum arabic for watercolors and gouache.
The ingredient in the vehicle of a paint which adheres the pigment particles to one another and to the ground. It creates uniform consistency, solidity, and cohesion.Also see adhesive, adobe, mortar and pestle, polymer clay, and solvent.
Art Word of the Day
Every day I make an attempt to add a little bit more art knowledge to the Internet, one word at a time. Realizing there aren’t many comprehensive and complete online art dictionaries, I set out on a mission to compile my own.
Perhaps you've noticed that this post has been downvoted/blacklisted and you're wondering why?
if you'd like to understand why Steemit is failing and how you can help:
You can take a valuable lesson from this. Democracy solves the problem of tyranny, and Steemit whales are tyrants. Let me introduce you to 
My only method to combat the downvotes is to spam
Ironically enough I only posted twice a day until I started getting downvoted. Now I automatically post up to 4 times an hour in hopes to get this message out. If the downvotes stop and I'm removed from the blacklist I will gladly go back to posting twice a day. Ideally the blacklist should be removed altogether, but considering the number of TERRIBLE ideas that have been put forward by Steemit Inc. recently, I sincerely doubt much will be done.
Don't like themarkymark either?
Unvote themarkymark for witness here
"I've never seen anyone leave such a long trail of blazing dumpster fires. I now believe the wreckless downvoting and blacklisting of thousands of accounts by themarkymark et al is the SOLE reason the price of Steem continues to fall. I didn't even make the photo for this post. That's right, I found it online. Fucking amazing."
Look at all these complaints from people all over the Internet
Most of these are written OFF of Steemit so as to avoid being downvoted and hidden. Amazing. So much for this "censorship-free blockchain".
