Thanks,
That seems logical. reminds me now of the story when graphite was found in England around 1500 they thought it was lead (metal instead of mineral) hence the misnomer "lead pencil".

It probably doesn't matter much, but I'd guess sharp sand because the grains are sharper and therefore should have more holding power. Brickie sand tends to contain more clay, but you are adding plenty of clay so there is no advantage there. I use silica sand.

Thumbs up Re: Australia - What Mortar to use?

Bert,
stick with the brickie sand as it is 'fattier' and holds/sticks together better than the 'sharp' concrete sand. You must however use fireclay in your home brew.
