Glass Muller for Making Paint, Mineral Pigment Grinding Pestle Flat Bottom Glass Grinding Apparatus for Watercolor Oil Painting Tempera Homemade Making Paint

I use it to make watercolor paints from mica powders, works great, best against glass

This is a great little muller. It's very small and sometimes hard to handle due to size. However, it does do the job. It's also great at mashing makeup powders and such.

This adorable little muller looks so tiny next to my already somewhat small regular muller! It is the size it advertised in the listing, the photos are a little deceptive, unless the person 'holding' it has exceptionally small hands, so ignore the photos and look at the listing details.I use my mullers for watercolor paint making, and it is perfect when I want to make a very small batch, either just topping off a pan or experimenting with a blend, just break out my smaller slab and do a bit of grinding. It works great for that, the bottom is flat and has a nice grinding surface, it does a good job mulling even if it is just the tiniest little muller I have ever seen.
