Chelsea Classical Studio Clarified Lean Medium is a handmade oil medium that uses lavender spike oil essence, which is a safer alternative to ones made with turpentine. A 'Lean' Medium refers to the 'Fat Over Lean' technique, which means to apply a paint layer rich in oil (fat) over a layer with less oil (lean) on a painting. This simple principle is fundamental to controlling the paint adhesion, drying time and glossiness of oil colours.

This is crafted from a mixture of pure, extra-pale, cold pressed linseed oil and lavender spike oil essence. Even the ingredients in the mediums are handcrafted to ensure the highest quality products. This fine-art quality medium has a light oil content mixed with a varnish, so it will thin the paint, make it dry faster, and is recommended for the early layers of painting.
