It's not unusual for art students to look to the waste bin for art supplies. I've seen sculptures made from broken forks and Barbie dolls, collages made from recycled magazines, and even paintings made from the odds and ends of paint jars. But Ariane Prin, a recent graduate from the Royal College of Art in London, took it one step further by creating a machine that turns art school scraps into something that can be used in every medium of design: pencils.
Prin first came up with the idea when she noticed the sawdust piling up in the school's woodshop. By combining the sawdust with flour and water, she created a paste that dried into a chunky but tough material, and one that she could use for a pencil casing. For the lead, Prin experimented with materials from each department, dried-out clay from the ceramics department, liquid graphite from the glass department, or leftover ink from the printmaking department.
Here's a look at the development of her design from hand-pressed molds to DIY extruder:
