Bleeding Glass

Deep withing the Green Island, lumberjacks discovered a strange phenomenon. Inside old Kapok trees lies a glass like structure, forming about 10% of the tree's size, shaped like the tree itself.

Description:

It's a glass tube filled with a few pieces of wood and tree some in the middle, making it look like it's bleeding when damaged. The glass itself is of decent quality and partially see-through.
While it's mostly clear, sometimes it mixes brown, green or even yellow-ish brown coloring.

Uses:

It is mostly used as jelwery or as a decoration, often higly priced, since it's difficult to get, not to mention most people and religions oppose destruction of old Kapok trees.
It can't really be reshaped, as high heat messes with the material, making it impossible to properly reshape. However, it is more durable than regular glass, which might eventually find a use.

Melting point:

• Melting: 1438 Celsius
• Boiling: 2650 Celsius

Lore:

It is said that Bleeding Glass is a start of the dying process of Kapok trees. Eventually they'll completely turn to glass, leaving little to no wood behind.
Some religious officials, mainly those from the Circle of the Forest Keepers, say that if people don't take care of trees, the young ones will die out, leaving only the old ones, which will eventually turn to glass, making it impossible to get wood, resulting in the fall of civilization.
Another version tells that Kapok trees are the hearts of the jungle, feeling every bit of pain inflicted on it. The more people harm the jungle by chopping down trees, the more pain Kapok trees feel, which slowly materializes as glass.
