Amber
One of a number of fossil substances that resemble the resins. It is found along the shores of the Baltic, and occurs in beds of lignite in many localities. With friction it becomes highly electric. It is a mixture of several resinous bodies; it also contains succinic acid. Only one eighth part is, in its natural state, soluble in alcohol; but it dissolves readily after it has been fused, in which state it is used for a varnish, etc. It is composed of carbon 80.5, hydrogen 7.3, oxygen 6.7, ashes (lime, silica, alumina) 3.27.
