Early Classic refers to 18 versions of Classic released from May 16 to May 28, 2009, that succeeded pre-Classic and preceded Multiplayer Test. Creative singleplayer was the only mode available at this time and there were only a limited amount of blocks available in-game.
Only appear naturally in one block-thick beach (usually by water or in the middle of a landscape). These beaches were always at and below ocean level.
Rather than falling by turning into a falling block entity, sand instantly appears at the lowest point it could go when placed above an air block, without any sort of falling animation.
In the early water test, water rendered as an opaque block. With the addition of lava, both liquids rendered as transparent. Lava was later changed to opaque.

Trivia
Once during the development of Java Edition Classic 0.0.14a, Notch tested vertex offsets of blocks, but was not satisfied, likely in part due to a graphic bug which showed block previews and highlights as cubes. [1]
