0.0.19a^[1] is a version of Java Edition Classic released alongside server version 1.5 on June 19, 2009, at 22:35 UTC, which added sponge and glass.^[2]

Glass^[1]

• Glass is textured, but is semi-transparent.^[3]
  • It does not render in the hotbar and when underwater.^[4]

Sponge^[1]

• Used to dry up a 5-block-wide area of water or lava around the sponge, 2 blocks to each side of it.^[5][6]
• Disappears after a while.^[7]

Hotbar^[1]

• Visually displays available blocks.
  • Blocks beforehand were still available by pressing different number keys, but had no UI display.
• The top texture is rotated such that the "down" (positive Y) direction of the texture is toward the top-left.
• Different sides of items are shaded differently. If a fully white block existed, its top face would be fully white (
   #FFFFFF), its left side
   #999999 and its right side
   #CCCCCC:
• The appearences of existing blocks are as follows (glass, still water, flowing water, still lava and flowing lava appear entirely invisible, but are included in these tables for completion):

The nine available blocks

Stone	Dirt	Sponge	Planks	Sapling	Log	Leaves	Glass	Gravel

Unobtainable blocks
