When I fell off into the void while wearing that fashion goggles from Thaumcraft, I saw some nodes on about Y 8. So I put some water on top, got some Angel Blocks from a reward and put them on the bottom. Made a little platform and collected them into jars, put them into my Thaumcraft room and everything is fine. My wand is never leaking out of any aspect. There were also generated "pure" aura nodes. Pure win I guess. (I've done that Thaumcraft stuff only till the equal trade)
But when you need on your research table, put some of these decorative shards around your research table + use a deconstruction table from Thaumcraft. But I guess you already knew that.
