I'm interested in developing some glazes that I can use as a top
layer, around the rims of my pots, that will run/bleed/feather in
interesting ways over my normally stable glazes. As a starting
point, I was considering using one of my regular glazes and adding
progressively more frit, which should flux the glaze more and make
it runnier. Any comments on this idea, or other suggestions? If
you have a glaze that works well this way, I'd be interested in
seeing the recipe, too. Thanks.

Chris,
You did not mention what temperature you are firing at or if you are
firing oxidation or reduction so I will comment as if you were talking
about a stoneware glaze. The atmosphere in the kiln will have it's effect
as well.
To that clear glaze, try adding Ceramic Rutile in increasing amounts like
your idea with the frits. At stoneware temperatures Rutile, besides being
a coloring agent, is also a flux. In some glazes, as it cools, it
develops tiny crystals in the glaze that can be very visually
interesting. Also, if the mix is just right, the crystals will form just
as the glaze sags on the pot forming the Hares Fur type glaze you might
have heard about. The infamous Floating Blue glaze is such a beast. The
blue color comes from Iron added to the glaze or from a red clay body
fired in reduction.
I do not believe that Rutile acts as a flux at earthenware temperatures so
this information might not apply. If any of this information is wrong,
I'm sure someone that knows more about glaze chemistry than I do will tell
us and we will both learn something new. Good luck with your tests. let
us know how they turn out.

I, too, love runny glazes (much to the dismay of my shelves, but that's a
whole other story). I have some Bill Campbell pieces with the most
spectacular running glazes I've ever seen - would love to know the secret.
In any event, I have a few glazes that do work for runny effects, although I
never use them inside anything because I don't know the effect it may have
on food-safety issues. Some are just runny glazes, some feather, others are
some I've been developing that run with small crystals in the bottoms of the
drips. Also, I have a recipe for some slips that a wonderful artist in
Philadelphia developed to use under her glazes, which give a nice,
high-fire, runny look without the actual hazards of runny glazes.
All I have are cone 6-7ox, let me know if this is in your range and I'll be
happy to send them along.

To everyone who has written about the glazes I mentioned: I PROMISE to post
the slip recipes and glaze recipes this coming week. I have an opening
tomorrow night that has become an intense labor of love for everyone
involved, so I won't be able to put the recipes together and post them until
after that, but I will post them on the list for everyone to try &
experiment with. Hope no one is disappointed with the wait.

Hi Chris - hey - I'm only 4 days behind - I'm catching up.
To make a glaze runnier simply take out clay - say 1% at a time - merde -
have I already sent this tip to you?
Watch out for crazing as you will be raising the expansion. If that happens
then start adding frit - 3134 would be the best because it has no alumina.
