So when this video starts, you see a fearsome monster. You’ll quickly recognise the careful trace-lines.

But you’ll also see some thicker, lighter lines.

Now these lines are half-tones made from glass paint mixed with oil.

All on top of unfired glass paint mixed with water. Unfired.

And in this video you see how we turn these half-tones into gorgeous shadows.

Remember: this is oil paint on top of unfired tracing and shading.

You see how easy shading is with oil – with the right oil, and with the correct technique.

That’s how useful oil paint is – when you know how.
