Gesso is made from ground marble dust. Some acrylic painters besides using it for canvas surface prep will mix it with their acrylic paints. It has a sort of chalky effect and makes the painting a bit out of focus. If you have a canvas that has gesso on it, you will see it labeled either portrait or regular canvas.esso is a thick white pigment designed to cover untreated and unprimed canvas. The gesso has two purposes. The first is to cover the unprimed canvas so that the paint you apply does not bleed through the canvas.

Potassium iodide is an inorganic compound with the chemical formula K I. This white salt is the most commercially significant iodide compound, with approximately 37,000 tons produced in 1985.It is less hygroscopic (absorbs water less readily) than sodium iodide, making it easier to work with.ith pure water, the concentration of KI in the solution depends only on the temperature. Potassium iodide is highly soluble in water so SSKI is a concentrated source of KI. At 20 degrees Celsius the solubility of KI is 140-148 grams per 100 grams of water.
