Unlike traditional acrylics, OPEN Acrylics undergo an extended period without skinning over that allows its tactile qualities to pass through distinct stages, the initial slippery and oily feel becoming gradually more pully and stiff. Along this gradient many painters will find what is often termed a sweet spot that suits their particular technique.The extended open time allows artists to more easily explore techniques such as portraiture and landscape painting that rely on softening, shading, glazing, and creating fine detail.
