Blink Ink for Clay is a specially formulated underglaze for use in Blink Markers.
Blink Ink settles out very quickly. I tested various suspension agents but I like the look of the ink without it. Do not be alarmed if your ink settles. Just shake it back up!
Blink Ink has been tested at earthenware temperatures (^06-^02) and up to ^10. It has even been tested over an already fired ^03 majolica glaze and it worked great.
