Which is why I mix them all carefully, grind together in a coffee grinder and then mix again. I also make sure I mix the mix carefully before extracting the mixed cure for use.saucisson wrote:Mixing nitrate in with large amounts of salt and sugar and then using a small amount can be extremely dangerous due to the different particle sizes meaning you cannot guarantee effective mixing.
In any case I have some slight doubts as to the validity of this idea of yours. If it were true, using any of Franco's pre-mixed cures would be dangerous, because they DO have different particle sizes, the sugar crystals are significantly bigger than those of some of the other components (it's hard to know what they are as they all seem about the same size).
Actually, taking a representative sample of a heterogeneous mixture is not that hard. Even the charge hand at Stepney Power Station 48 years ago was capable of doing it!
What does need stressing is that it's important to remix the mix before extracting part of it.
