I love to use acrylic paints, especially because they are water-soluble
That's interesting. I don't know much about different paint types. Can you tell me more about acrylics
Acrylic paint
Acrylic paint is a fast-drying paint made of pigment suspended in acrylic polymer emulsion. Acrylic paints are water-soluble, but become water-resistant when dry. Depending on how much the paint is diluted with water, or modified with acrylic gels, mediums, or pastes, the finished acrylic painting can resemble a watercolor, a gouache or an oil painting, or have its own unique characteristics not attainable with other media.
History.
Otto Röhm invented acrylic resin, which was quickly transformed into
Acrylic painting techniques
Acrylic painting techniques are different styles of manipulating and working with polymer-based acrylic paints. Acrylics differ from oil paints in that they have shorter drying times (as little as 10 minutes) and are soluble in water. These types of paint eliminate the need for turpentine and gesso, and can be applied directly onto canvas. Aside from painting with concentrated color paints, acrylics can also be watered down to a consistency that can be poured or used for glazes.
