What is an example of a binder in art?

What is a solvent in paint?
Solvents in Paints and Coatings: In paints, solvents dissolve or disperse the components used in the paint formulation, to make paint the desired consistency for application and to avoid clumps or globs. Glycol ether esters are added to some spray paints to prevent them from drying in mid-air.

This means that they serve to bind together the other components, and allow them all to come together to make a film which lies on top of the paper. The resins also serve to provide an adherence to the material upon which the inks are printed.
What is the difference between acrylic binder and acrylic medium?
Binder gives acrylic paint its natural adhesive properties. A good example acrylic medium is glazing medium, which allows you to create a thin, semi-transparent paint mix with a touch of colour, that you can then ‘glaze’ over the top of your entire painting.

How do you make paint out of rocks?
Rub two pieces of sandstone together until you get a decent amount of coloured dust (ochre). Then, using a paintbrush, add water and continue adding small amounts of water directly to the rock until the powder has turned into a paste.
