cracking in functional glazed ware

I would be looking for clues as to why such cracks are appearing - not a way
to patch them afterwards.

I would either sell them as 2nds (if the cracks were on non-food contact
areas) or use a hammer judiciously.

Only my $0.02

I am looking for a non-toxic filler/glue to repair small cracks that
sometimes appear in my glazed ware.Does such an animal exist?

The best way is to repair the glaze!
It is mostly possible

If cracks appear in ware that has already been fired there is certainly a
problem that presents a danger to the user of those pots - if they are used
for food.

There is only one reason for ware to crack spontaneously - the glaze winds
up - during cooling - too big for the clay. It's called shivering or glaze
dunting.

Small flakes of glaze can fall off the ware - into food - these are as
sharp as broken glass - not what we want inside us.

I'll be glad to asses your glazes for you - if you are mixing them yourself
- just send me the recipes - to: ronroy@total.net

I may be able to fix them as well.
