cyanotype class

not starting art every day month off so well- though i did art related things thursday night (first thursday at the gallery- we rotate through on the serving committee & i was in the group) and friday (we went to see kt tunstall and were reminded again of the art of the performance. she was really good- great energy, voice & guitar, small venue. loved it).

back to art making today. nancy, zella & i, along with 3 other artists, took a cyanotype class at wingtip press . instructor mary donato uses a variety of alternative processes for printing images. turns out that alternative processes are often old fashioned methods. cyanotype uses ammonium iron citrate and potassium ferricyanide (solutions a and b),


equally mixed, to coat any porous material., in this case paper.
 
 the solution is yellow when applied

paper hung to dry in a dark area. you can see the wide variety of paper that was tried. participants also used cloth (natural fabric only), tiles (uncoated) and we even tried metal, which didn't work so well, but well enough to warrant further experimentation.


the coated paper is placed on a board under a negative, then a piece of glass is put over the whole thing & clipped on. these pieces are developing in the sun. it was a cloudy day, so there was a long development time, but the process is inexact, and the sun would come out, then go away again, so there's a bit of trial and error.

this is zella taking apart a finished print. the image is one she drew on a transparency. you can see the olive green at the bottom- that's the color indicating that the print is done.

here is one of mine just after being taken out of the press (for lack of a better word).

the images are developed in water. here's another of mine (which ended up quite over exposed) in the water bath. you can see the color starting to develop.


the flowers once developed & dried. the prussian blue (those of you who read the blog know this is one of my favorite colors) is the distinctive color of a cyanotype print.


another of mine, this one on rice paper


 this is mary, explaining various toning procedures just in case one isn't as fond of prussian blue as i am. or if someone just wants some different effects. the tannins in tea cause a chemical reaction that creates a purplish or brownish color. images are first bleached in a washing soda or tsp solutions, which can also help bring out detail in over exposed prints.


this is the overexposed print from the top- the tsp bath brought a lot more detail out in the sky above the tree. the color change is due to the tea bath.


two more of my prints:






i'm looking forward to playing more with this and to incorporating these into future mixed media projects. i just love finding new ways to use my photography in my art and am excited by the possibilities. what a great art day! not only did i learn fun stuff, i got to play with nancy & zella & meet new artists.

tomorrow is studio floor painting & and wall touch up day, but i do have a few pieces of paper coated with solution to play with too.....

What an intricate process - it was really fun to learn a bit about this type of print. The birds and the tree are my favorites - I think the blue is great with them.

Oh Marianne, what fun!!! I want to learn this! I LOVE the tree print! I admire your "art everyday" practice. I am busy doing other things (soon to be packing, moving, traveling... so no time for art now- but in January- look out! I will work less, and do art more!!)
:)

That is quite the process! I really do applaud you for taking the time to walk through your process. It must be so much more time consuming when you do that but I know it is greatly appreciated. I tried that "art everyday" a while back but ended up feeling pressure to create something. Obviously, I tossed that idea aside fairly fast. Have a wonderful Sunday, Marianne!

Wow! I have some sun print paper that I've been wanting to use for a while, but seeing how you've made your own is really fascinating. I think your prints turned out great. Thanks for sharing!
