SAN'DARACH, n. [L. sandaraca.]

1. A resin in white tears, more transparent than those of mastic; obtained from the juniper tree, in which it occupies the place between the bark and the wood. It is used in powder to prevent ink from sinking or spreading. This is the substance denoted by the Arabic word, and it is also called varnish. For distinction, this is called gum sandarac or sandaric.

The sandarach is obtained from the Thuya articulata, from the Juniperus cedrus.

2. A native fossil; also, a combination of arsenic and sulphur; orpiment.
