Muller

A tool made of stone or glass used to grind pigments on a flat stone in order to mix them with a linseed oil binder. Before the 1840s, this was the laborious process necessary for producing oil paints. Only after Cole's time did premixed paints in collapsible metal tubes became widely available. In the 1990s, two mullers and a grinding stone were found in Cole's "Old Studio."
