looking for a nice running glaze

does anyone have a recipe for a base running glaze?  Yes, I know we all try hard to avoid this, but I'd like something to drip over the rim onto a colored slip surface, making nice pooly drips.  Thanks!

Very cool - and you're saying the pooling adheres to the piece rather than (gulp) to the kiln shelf?  Within reason, of course.  Have you tried adding color to this?

If your shelves have a good coating of kiln wash this glaze will sit on top rather than eating through the kiln wash and attaching to the shelf.  Picture below better illustrates this.
It ran too much for my purposes so I didn't really get into colorant testing but i'm sure it will  do alright with cobalt, copper, and iron in small amounts.

Thanks very much.  Just made up a test batch & will fire within the week.  Fun!

This is a berry bowl I made a long time ago...I used a ^04 glaze over a ^6 glaze ( in this case, it's glossy base 1 from Mastering ^6 with some zircopax and rutile in it)  Anyway, the low fire green (and also the blue version) ran nicely on the ^6 glaze- a nice accent, but not off the pot..

The ^04 base glaze is from clayart:

Frit 3195 73

Flint        7

EPK         10

Mg Carb    10

 

probably 4% copper carb for green, about 2% cobalt carb for med. dark blue..

enjoy!

Hi, Ginny.  I landed here via a search for runny glazes.   I would like something like this for the rims of mugs and bowls.  I have a lot of portions of low fire commercial glazes.  I may try a couple of these just to do something with them.  Did you try the recipe that George Lewter recommended?  I would like to know how they turned out.
