A few notes about oil pastel and pastel
Although they share the name pastel, oil pastel and pastel are really quite different from each other and cannot be used together. I used paper stumps to blend the pastel pencils. I tried to use the stumps to blend the oil pastel, but using my fingers proved more effective. The heat from my finger warmed up the oil in the oil pastels, which in turn blended the colours a lot better.
I didn’t buy any special paper for the pastel pencils. They worked great on Strathmore 400 Series 80lb drawing paper. For the oil pastels, however, I used a thicker paper so the oil from the pastel would not seep through. I used Canson 150lb smooth surface paper for the oil pastels. I would like the try the oil pastels on canvas one day.
Pastel sticks create quite a lot of chalk-dust, pencils create a lot less. That’s why I like the pastel pencils better. They blend very easily, they smudge easily too. Oil pastels have mineral oil which never really dries completely, so they would smudge as well. Therefore, both of them need sealing. I used Grumbacher Matte Finish Final Fixative to seal both of them. One thin coat was enough for the pastel pencils, but the oil pastels needed three thin coats. I did take the time to let each coat completely dry before applying the next one. I suggest you try out the sealant on a small test sample before you apply it to your finished painting.
I couldn’t find much information on this and had to figure a lot of this out by playing. So, in case you paint, I thought you might find this information helpful.
I painted this Field Of Wild Flowers with oil pastels in the style of Van Gogh. As you can see, they behave quite differently than pastel pencils. I wrote about his painting a couple of weeks ago in “The Master And The Apprentice“.
