    Nice, reading this thread you can use potassium nitrate ( KNO3) and Sodium nitrite (NaNO2) they shouldn't be hard to get in NZ, just need to get the mix right to get the right temp.

    Potassium Nitrate is super easy to get here. Just buy off trademe if you don't want to venture out to get some. We use it for speeding up tree stump removal. Unsure about Sodium Nitrate, but imagine it will be the same.
