Gerstaecker | Glass Mullers — for use with glass slab

Mullers act as flat-bottomed pestles, which are used to grind pigment into a binding medium, suspending it evenly to create a uniform covering of binder around each pigment particle.

Using a muller and slab (see item code 65613), rather than simply mixing pigment and binder together, will create a more homogenised and stable paint.

With oil colours you rub your pigments with (linseed) oil, with casein paint with casein. Acrylic colours cannot be ground in: you would get too much foam.

These Gerstaecker Glass Mullers are available in 2 sizes:

• small - Ø 5.7 cm / height: 4.7 cm / weight: 20 g
• large - Ø 8.5 cm / height: 8.5 cm / weight: 50 g

TIP! You can also use a muller to roughen a lithography stone with carborundum or fine silver sand. And you can use it to rub and smooth printing ink before you ink your printing plate.

TIP! By rubbing your pigments first with the appropriate thinner - white spirit or turpentine for oil colours, water for casein - you can disperse your pigments, if desired, before rubbing them into paint. Depending on the pigments you use, this sometimes works easier. You can also leave your pigments in the diluent in a sealed pot for a while - put to rot, painters used to call it.
