Soft Pastel in Mixed Media
In a previous blog I discussed how pastel can be dissolved with any liquid providing the paper or panel can take it. Pastel can also be applied on top of watercolor, gouache, acrylic, oil or any compatible combination for some interesting results. Here is an example of an orange strip of another medium and blue pastel on top. Remember, the support (paper or panel) for your painting has to accept the liquid so check first.

Note the last strip. The orange pastel was rubbed into the paper without using a liquid. When the blue is put on top, it physically mixes with the orange. Since they are complements, this mixture becomes a gray. In the other examples you can see the orange cleanly coming through the blue pastel because the orange is dry and cannot physically mix with the blue.
Here are some words of caution especially when using acrylic and oil. If you put a thick layer of acrylic or oil down first, you can fill the tooth of the paper. Then the pastel does not have the tooth or texture it needs to grab the surface. So, use a wash of acrylic and plenty of odorless mineral spirits when using oil. I prefer Gamsol for OMS. Also, remember the rule that oil paint can be put on top of acrylic but acrylic paint can not be put on top of oil paint.
In the example above, I used other media to make a solid orange strip but you can manipulate the medium to take full advantage of it's properties. Here are just a few examples.
I put black gesso on a panel and then used crackle paste in a stencil to make this pot. The type of crackle medium I used was more of a liquid and transparent when it dried. I put pastel on top of the dry crackle. The pastel grabbed it in an unpredictable way providing an interesting visual texture suitable for a clay pot.

In this landscape, I added transparent gesso randomly to add more texture to an already sanded board with tooth. Those marks grabbed the pastel and helped to make the grass and the ground cover.

In the next painting, I used thin washes of oil paint for an under painting. When you let the thinned oil paint drip, it makes luscious marks. Look carefully in the trees where I let some of this show through.

Here, gouache was used under the pastel. I let the colors of the gouache peak through.

If you have a disappointing watercolor painting, try putting pastel on top to fix it. If you forgot to save the white, well, there are lots of white pastels. In this painting, I used watercolor under the pastel. In fact, a lot of the blue in the sky is untouched watercolor.

Pastel is put on top of a mixed media collage in this painting.

Remember that pastel on top of another medium means that the painting has to be framed under glass.
So, try it all! It's fun. There are so many possibilities and so little time.
