Just one, as I rarely use it on anything but obsidian.
Or did you use the old lava/water method?
Yep. I poored water on a large lava lake that I had found down in my mine.
When that was mined out, I built one of those obsidian generators, that turn redstone into obsidian without wasting the lava source block in the process.
