That is why a buffer medium is used as a ground to prime and protect the underlying substrate, such as gesso, rabbit skin glue, etc. I'm sure you probably already know that, and I may have missed if you used a layer of clear gesso or something to protect the underlying pastelmat. I assume you don't want the painting to rapidly self destruct over the years. I'm not aware of pastelmat having a PH buffered layer already to protect it from oil mediums soaking into it. I'm happy to stand corrected if I'm wrong! I know people use oil pastels on various media without priming it but I have also seen many such paintings sadly deteriorate.Hyn Pattyhttp://hynpatty.comnoreply@blogger.com
