This has been a quick week- I was sick on Thursday. The two paintings below are finished and ready to submit to Turning Points Network to potentially use for their spring fundraising drive. It will be cool to see if they want to use one. I will let you know! I am blogging a bit a head of time as I am going to be here and there for a couple of weeks. This week’s on the media is The Moth Podcast where a police officer gets tripped up and tells his story to us for a good laugh.
Today I plan to start talking about some technical stuff about painting-I am going to call these sections of the blog TechTalk. Today’s TechTalk is on the subject of granulation. Granulation occurs when the pigment sort of drops out of the binder. I guess a brief discussion on watercolor paints is in order. Watercolor paints contain pigment, binders and a few other things. According to www.webexhibits.com ” In commercially made watercolor paints, the binder is either natural gum arabic or synthetic glycol. This is what holds the pigment in suspension. The binder also allows the pigment to adhere to the support (e.g. paper) once it is applied. Additives, such as plasticizers (e.g. glycerin) and humectants (e.g. honey or corn syrup), are mixed in to alter various characteristics of the watercolors, such as viscosity and durability of the paint. Other additives include extenders and dispersants.” Some pigments stay suspended “better” than others. I happen to love the random effects granulation gives. Cerulean Blue is one of the pigment known for it’s granulation. I like mixing colors with Cerulean to see what happens. Because I use cold press paper, there are peaks and valleys on the paper making the granulation effects pronounced. You can see granulation in the sky in the above painting of the children playing with the ball. Below you can see the difference in granulation between Cerulean Blue and another color called Rose( Larger red sphere in middle of page). I put the blue down first and let it dry. I also mixed Cerulean Blue with Cadmium Red ( smaller orangish sphere top left is mostly Cadmium Red) to make the grayish granulation you see and let that dry. One thing of note is how transparent the color Rose is. You can see right through it when it covers the cerulean and hence the granulation still carries. I will talk more about transparency later but it is another property of watercolor paint that makes this medium so awesome!
Ok- I gotta get out and enjoy the weather- until next week- Peace Out- Bec
