TECHNIQUE
Carborundum
Abrasive carborundum grit (silicon carbide) is mixed with acrylic medium or glue and painted onto a flat surface, such as plastic or metal.
The marks can be very painterly, thick and very textured or thinned with water to make more washy marks. Once dried, the carborundum and glue mixture forms areas of texture that can be inked intaglio. Other acrylic mediums and texture pastes can be used.
The advantage of carborundum plates is they are relatively cheap to make, so good if you want to work larger. In some etching techniques, the colour changes as you wipe the plate. This doesn’t happen with carborundum plates, so they are brilliant for printing bright, clean colour.

Collecting the Looking
“I love drawing really quickly. I love drawing in really difficult situations. I love drawing in the dark. I like what happens when you can’t see everything or when it’s passed and you have to remember it rather than drawing what it actually looks like, so it’s about the experience of looking as much as what I’m looking at.”
We talk to Michelle Avison about building a resilient artistic practice over 30 years.
