Rublev Colours' commitment to authenticity ensures that their Aqueous Dispersions contain only naturally-derived ingredients, free from coalescent solvents, artificial dispersing resins, and other additives that can interfere with natural mediums.

Ultramarine Blue has a rich history, dating back to 1814 when Tassaert first observed its spontaneous formation in a lime kiln. The Societé pour l'Encouragement d'Industrie later offered a prize for its artificial production, prompting Jean Baptiste Guimet and Christian Gmelin to devise processes to create the pigment. Today, Ultramarine Blue is a prized color in the artistic community, with a Colour Index designation of Pigment Blue 29 and Colour Index number 77007.

This extraordinary pigment boasts a high lightfastness rating, categorized as I by the American Society of Testing and Materials (ASTM International). While it is compatible with all pigments, care should be taken to avoid using it with acidic mediums and supports. When working with oil paint, Ultramarine Blue absorbs a moderate amount of oil, which may slow the drying process. However, its high refractive properties make it ideal for creating rich, luminous hues.

As a non-toxic pigment, Ultramarine Blue (Green Shade) is safe to handle, although caution should still be exercised. With its unique characteristics, including a specific gravity of 2.35, oil absorption rate of 38-42 grams per 100 grams of pigment, and median particle size of 2-4 microns, this dispersion is poised to elevate your artistic expression.

Whether you're a seasoned artist or emerging talent, Rublev Colours' Ultramarine Blue (Green Shade) 2 Fl Oz is your key to unlocking the full potential of traditional painting mediums. Experience the rich beauty of this captivating blue pigment, perfected by the experts at Rublev Colours.
