SpectraFix Natural Artist Materials was conceived in 2007 in the San Francisco Bay Area of Northern California, when artist Della Heywood created her first batch of natural casein fixative based on a 100 year old recipe used by Edgar Degas. Astonished at its versatility and delighted by its friendly fumelessness, she continued to use it in her studio for two years until finally deciding to create a product that other artists could enjoy.
