I just wanted to thank Linda for educating me about
earthenware. I was very prejudiced against it up
until this time. My daughter had picked earthenware
(imported I'm sure) for daily use when she got
married. I tried to talk her out of it because
several pieces on the display table had already been
chipped. Well she purchased it and she now has a lot
of chipped dishes.
I had even worked with earthenware before for
sculptures, tiles, and horsehair raku but was unaware
of earthenware durability.
Thanks for the free education!

Sorry - I can't let this go by - earthenware is not stronger than properly
formulated stoneware clays - it depends on what kind of testing you do.
There is no doubt that earthenware is more susceptible to chipping because
there is no mullite formation.
While it may be true under some circumstances and some kinds of testing -
earthenware may register a higher breaking point over some glassified clays
- because they are brittle - it is not the only gauge of strength clay
bodies can be subject to.
