This is a wonderful, fun glaze, that works really well over white and a variety of other colours. I find it doesn't look as good if the clay is it's natural colour. It is often VERY drippy, especially mixed with some other glazes so beware! (I used it over PSH Magenta Magic and it ran like a waterfall!). Testing is advisable! When it drips it actually looks brighter and more intense in colour than the cone 6 example. I usually fire it at cone 5 or 6. It responds well in slow cool firing. I highly recommend it!
