I finally had a little success getting the titanium white to break. Keyword is “little,” but the best I’ve done yet. This is my 23rd painting, so I’m still a noob. I discovered the titanium white I was using was the bigger problem. I had ordered Bob Ross white from the actual company in the larger plastic container and it was too thick. It was full of chunks of solidified paint. It was almost like pieces of rubber. I bought a 200ml tube and that was much smoother. Of course, many of the Ross paints are separated.
