This solid carbon (graphite) block has all the known elements of the universe laser etched onto it. A wonderful display and conversation piece.
It's a solid block of pure carbon in graphite form. We recommend handling it with gloves (think about handling pencil graphite). On the reverse is specific information about carbon, the building block of all life on our planet.
Besides being responsible for all life, did you know carbon does not melt? Rather than melt, it changes directly from a solid to a gas at 3550C (3823K). It is only when it is placed under ten atmospheres of pressure that it is possible to observe it in a liquid state.
