Summary
A new slab type introduced in beta 1.8. It uses the top texture of the normal stone slabs on all sides. There doesn't seem to be any crafting recipe for it, it used to be obtained by using a inventory editor block id=44:6, however after recent updates, the block is no longer available. Jeb tweeted that he will add the block as 43:8. On the picture it's next to a normal double slab so you can see the difference.
