You can boil it out, but thats usually for cleaning it. The best way to scrape it is to use paper clips, starting in the carb to clean the main chamber. If the resin is dry enough, it should come out, just scrape a little, then knock the bowl a little and it should fall out. However, smoking resin isn't really worth it, it mostly consists of tar, true little pieces of bud and trichomes fall into the bowl and get stuck in the resin, but it's still mostly tar and really not worth smoking.
