CTS gum mastic — natural resin in tears for preparing painting varnish
Natural resin from the mastic tree (Pistacia lentiscus) that, according to CTS, comes from the island of Chios, in Greece. It comes as light yellow, glossy, transparent tears. These are resin tears, not a ready-made varnish: the varnish is prepared by dissolving them. Because of its transparency and gloss, CTS indicates it mainly as a varnish for paintings.
What is it used for?
- Preparing mastic varnish by dissolving the tears in turpentine
- Final varnishing of easel paintings, on canvas and on panel
