I saw that the Potion of Night Vision had an enormous EMC value, and as I checked through the recipes, golden nuggets get a substantial boost to 227,556 (each!), from a gold ingot of 2048. Going through the other recipes for the golden nugget, the only recipe that could cause a problem that I can see is the Thaumcraft smelting of a gold coin to get a golden nugget (gold coin is unassigned). I single potion of Night Vision gives you more EMC than a bock of Aeternalis Fuel...

I am such an idiot... That is clearly a decimal... Apologies.
