hang10tiki your wish has come true.

=========================

The HORRORS of ceramic art.

I opened the kiln and learned a huge lesson about under-glaze versus regular glazes.

When drying I saw some small separation lines (cracks like on the desert floor) in the glaze on the inside bottoms of the mugs. I thought when the glaze melts they will come together. NO they separated much worse.

So all but 6 mugs needed to have the insides re-glazed with regular glaze to fill the separations.

Out of the 36 mugs I had these three where the glaze separated or sloughed off.

Here is the other side.

The robot melted and

the cat drooled glaze on it's face and separated in other areas.

So I will play with these three mugs to see if I can save them.

I brought all the mugs into the kitchen to re-glaze.

I would take them to the garage to dry in front of the fan. Then into the shed.

At the end of two days I was ready to fire again. The glaze inside the mugs was still damp so I did a 10 hour pre-heat and

a 13.5 hour slow ramp. Plenty of time to dry and to fire.

My hope is that the mugs that were OK will not separate and run with this second firing.

Cheers, Wendy
