With using lye in that kind of concentration be very careful. that ph is probably sky high in that water so when you mix it watch yourself.

People that have done the drytek; do you still use jars for this?
I picture trying to pour the naphtha out and the mhrb mix just falling with it or bits of it at least.
I can see how you'd get naphtha out by using a load of it, my friend doesn't want to be wasteful though.

Filtering perhaps...
