Ronan, what is HTI dust. It's not an acronym I know, but I am getting a copy
of Hamer's Encyclopedia for my 60th birthday tomorrow, so the morning will
possibly bring an answer.
Really, though, anything of a stone/clay/mineral origin and a dust nature is
probably worth experimenting with and getting an analysis of what would
enter into the glaze formula.

Hi Martin,
sorry to be be so long replying.
I have just got back after firing my kiln on Friday. Unpacked this
morning, won't be able to give a verdict until I have spent some time with
the work, some interesting glaze tests though.
Nearly 300 messages to wade through !
HTI is short for high temperature insulation bricks, AKA soft
firebricks, insulating firebrick (IFB), K22-23 etc.
So what is that stuff ? Mainly silica and alumina and not a lot else
would be my guess.
Ronan
