Abbots Cobalt Blue Midfire Brushable Glaze is a deep glossy, reactive, foodsafe (in Abbot's opinion) blue glaze. Can be applied thickly.

Most Abbots glazes are very well suspended. If you wish to enhance the suspension qualities you can do this by cautious incremental additions of calcium chloride, epsom salts or plaster of Paris before sieving.

Firing Abbots Mid-fire Glazes

We do all our development work in a 1 cubic foot laboratory kiln and to ensure representative results we set our programmer as follows:

Ambient to 200°C	100°C per hour
200°C to 1050°C	300°C per hour
1050°C to 1200°C	80°C per hour
Soak at 1200°C	30 minutes
1200°C to 1050°C	80°C per hour (fire down)
1050°C to 900°C	as fast as possible (applies to iron glazes)
900°C	soak for 1 hour (applies to iron glazes)
Cool

This firing just bends cone 6 in our kiln. If you follow a similar routine and also bend cone 5 or 6 you should get similar or identical results. You may have to set your controller anywhere between 1180C and 1220C to duplicate these results - all kilns are different.

Some glazes may respond better to different regimes and a wide array of results is possible. The iron red glazes respond well to a fast cool from 1200C to 900C with a 1 -hour hold at 900C. We have not yet tested every option.

The iron glazes are very fluid but work best with a thick application. Experiment with a sacrificial catch-tray under pots until you have mastered them- and bat-wash your shelves!

Do experiment with multiple layers of different glazes for unique results
