What are Pigment Sticks?

Pigment Sticks are oil paint in a stick form. They are composed of linseed oil, natural beeswax, and pigment. Due to our unique formula, Pigment Sticks are buttery smooth and quite fluid. They dry to a tough, flexible oil paint film. They are sometimes referred to with the more generic term "Oil Sticks".

What is the difference between oil sticks and oil pastels?

The difference between oil sticks and oil pastels is the type of oil that each is composed of. Oil sticks are composed of a drying oil (linseed oil). Works done in oil stick do not need to be placed under glass for presentation, as the surface is a dry, tough, flexible paint film. Oil pastels are composed of a non-drying oil (mineral oil). This would necessitate placing them under glass so that the surface would not be damaged as it will not dry.

What are appropriate sizes for Pigment Sticks?

The term "size" refers to a penetrating liquid, usually a hide glue or resinous mixture, that is employed to make a surface less porous and to isolate coatings. In most cases, the application of the size should be dilute and just enough to absorb into the support. It should never be a film, as this can lead to cracking in the long term.

* Proper sizing will protect the support from being damaged by the acidic nature of the linseed oil.

There are 2 groups of sizes: Reversible & Irreversible

Suitable reversible sizes for Pigment Sticks are:

bullet

rabbit skin glue

bullet

methyl cellulose

bullet

gelatin

bullet

white shellac

Suitable irreversible sizes for Pigment Sticks are:

bullet

GAC 100 (Golden Artist Colors)

bullet

PVA glue

What are appropriate grounds for Pigment Sticks?

The term "ground" refers to the actual surface to which paint is applied. This layer is usually applied after the support has been sized. This process is also known as "priming." Applying a ground offers a foundation of uniform absorbency; a white, non-yellowing layer that will afford maximum luminosity to the painting; and a structure that will offer sufficient "tooth" for the paints to adhere to.

Grounds can divided into 2 categories: Absorbent & Non-absorbent

Absorbent grounds are:

bullet

Acrylic gesso

bullet

Traditional rabbit skin glue gesso

bullet

Clayboard

bullet

Clay-coated paper.

Non-absorbent grounds are:

bullet

Oil ground

bullet

Wax ground
