I'm needing to put a different (non-toxic) liner to some bowls and would =
like
some tips on getting a nice, clean line between the exterior and interior
glazes. Any suggestions? Do you use wax resist and if so, how do you apply=
it.
My first attempt left little patches of unglazed area along the lip.
Thanks,

This is a very important question. I'm glad it came up. It takes extra
effort to put a liner glaze in your mugs but its worth it.
There is a web page on this at
http://digitalfire.com/education/glaze/liner.htm. Here is a summary:
1) fill the mug up with liner glaze and pour it out in a circular motion
and then dip the lip into the glaze about 1/4 inch.
2) put it on the wheel and wax up inside starting about an inch down
and up around the lip down about 1/8" on the outside
3) Use a sharp knife at a 45 degree angle and turn the mug to take the
glaze off the lip and down the outside. When done you should have a
perfect edge of waxed glaze that stops at the centre of the lip. It
should
be at the centre so that any flow goes back down rather than across the
join.
4) Wet your hand (so it won't pull off sections of wax when you touch
them) and first dip the lip about 1/2" into the colored glaze, then
immediately turn the mug over, put your wet hand inside, clamp against
the interior surface, and jerk it downward lightly to encourage the
colored glaze on the rim to pull down a bit. Press the mug into the
colored glaze to overlap the lip dip just made. Pull it out and hold
at an angle so drips fall off one spot.
5) Sponge away any drips of dark glaze over the liner on the inside
or the lip.
You need to use glazes that are not too fluid or they will bleed into
each other at the join. However when done right this method works
really well.
This method of glazing leaves few drips. Even an undecorated mug with
a different colored inside and outside looks appealing (i.e. Denby).
It is also a public declaration that you as an artist recognize your
accountability for the safety of your ware.
