Hi Gayle, Vince...
The subject line is starting to sound like one of the lost verses from the
song 'These are a few of my favorite things...' or whatever it's title
actually is...
Yahhhhh...Mug-Bottom wise, a wired-off, once dry enough then
rolled-around-at-an-angle to kill the hard edge and make a small shadow line
and small in-slanting to the verymost base, thence 'spanked' to recess the
middle slightly, makes a very nice 'foot' and bottom, for a Mug...at least
to my minds and eye.
That way too, only that thin downwardmost slightly inside area of the
peripheral rim is touching whatever the Mug is set on.
Look at any old 'Hall' or 'Tepco' or similar of earnest Mug from decades
long passed...and, you will see a concave bottom and roundish peripheral
'edge' to their Bottoms, and, this was no incidental of course, but rather
an indicator of good design and function for how the Mug sits and for how it
translates less heat to whatever it is sitting on...
'Bad' imported low fire 'mugs' with otherwise maybe appealing graphics or
hip allusions of some kind, the ubiquity of 'office' and 'home' use anymore
for millions of people, can be seen to posess 'dead-flat' bottoms in many
cases ( the mugs I mean, not the people, per-se).
And, a 'dead flat' bottom is a bottom someone forgot to think about, or did
not care to consider critically in terms of design and function, while
indicating neglect or confusion aesthetically, also...
I can not think of any functional form for which a 'dead-flat' Bottom is
forgivable...
Love,
Phil

I am not so sure, I have started to make pie plates and chicken rosters
with a dead-flat bottom and think it works better then a foot on the
bottom. I end up with just a nice curve into the bottom that slides in
the oven very nicely.
We were having a problem with oven ware cracking before we stopped
trimming the bottom and now we do not. I am not sure the foot ring had
anything to do with it or if I am just getting better at making them.
