it it was all sublimed, then you would need fresh stuff. BUT the E is probably toasted...you could try putting new I2, add a little water and just cook/reflux it at about 100C for however long you want- longer is better. you may or may not get anything, depending on how much E survived. the only thing thats probably still alright is the RP. check out some of the links in the 'Stimulants FAQ' for more info
