Emberock

Emberock would a block that reacts to light. It generates in caves, near lava lakes, where the light from lava can keep it on.It can be mined by any tool with Silk touch. Its mechanic is that it can spread light. It takes in the light level around it, and echos it, using factors of 3.If the light level is 15, it emits a light of 15.If 14, it rounds down to 12.When lower then 12,to 9.At 3, it emits no light at all.After a very, very long time, they burn out completley, and become stone.
