I haven't the faintest idea having never tried it Larry, sorry. But they're intended to be used with water so I imagine the results would be a little odd at best :)
Paul Foxton that is the exactly the answer I was looking for. I have a bunch of colored blocks coming to me that I’m planning on experimenting with some different ways to apply the pigments. I’ll try the oil with a bit on a pallet. Thanks for the video, this was a lot of help Charles
