With the discovery of Ichor, you have also unlocked ProjectE. With this, you can start to harness the power of EMC.
The Philosopher's Stone will allow you to get an Energy Condenser, which makes crafting with EMC a possibility. This is also highly recommended to get before starting on the Creative Items.
When you have some Chaos-Blended Ichor, you can also make the Transmutation Table. This is the most expensive recipe in terms of Vis cost in the pack, so be prepared with the best wand you can get.
Good luck.
