Beware of bits of rock guised at pumice.
on 3 June 2015
I was surprised how large the pieces of pumice were, but most of them responded to a gentle wacking with a mallet! However, during the process I discovered that quite a few of these pieces were not pumice but rocks! We now have chips out of the patio!!
So, beware of this.
