Uses Glowstone Dust in the creation of light-emitting Sand- and Glass-based blocks.
Brightsand:
Can be crafted into Bright Sandstone like regular sand
Bright Sandstone can be smelted into Smooth Bright Sandstone
Each Brightsand-type block emits a light level of 10
Brightglass:
Smelted from Brightsand, like regular glass
Crafted into Panes the same as regular glass
Both Brightglass and regular glass panes can be converted to and from plates by placing them alone in a crafting grid
Misc:
Plates can be placed on either the top or bottom of the block they occupy, similar to slab-type blocks
Plates can also be waterlogged, so you can hydrate crops and plant sugarcane without crops (or you) falling into the water.
Glass and Brightglass now drop Shards and Broken Glass, which can be smelted into Panes and Blocks, respectively
Silk Touch tools drop the block as normal
