Logs

The glass log has a similar pattern to the oak log, but with glass style and color. Bone logs uses the Bone Block texture, but with a set block bounds. You don't actually need use an axe to cut then, the glass works like normal glass where you break it with anything, same with the bone. Glass and bone logs are not flammable. There are also no glass and bone planks. Glass logs can rotate like normal logs, but the bone log doesn't.

Obtaining
Glass logs can be broken by hand, like normal glass, using an axe doesn't really make it go faster like it would with normal wood logs.

Bone logs can not be obtained in survival. Once broken, they give 0-3 bones.

Naturally generated
Glass logs generate as a part of the glass tree that can only be found in the Glassland biome.

Bone logs generate as a part of the bone tree the can only be bound in the Bone biome.

From sapling
Glass trees have a sapling, which looks like a glass pane, and can actually be bonemealed to grow the tree. They can grow on their own time too.

A sapling for the bone tree is actually in the code, but it is not registered into the game. This was for testing. You can not grow a bone tree.

Usage
There is no glass planks, but the glass log does go into 4 normal glass blocks if placed in the crafting grid. Bone logs don't give planks either, and they don't drop themselves.

Glass logs and bone logs can not be smelted to get charcoal. They also can't be used as a furnace fuel.
