Lions

I took all of the pieces out of the kiln this morning, here’s a couple of the lion blocks nr. 1265 which turned out great;

The other pieces had some wierd issue I have to find out the cause of, meanwhile I came up with both a weight and size loss chart for the 3 lions;

#1 dry weight: 7.80#
#2 dry weight: 8.00#
#3 dry weight: 8.05#

Original model size as molded: 10″ x 4-1/4″ ( 25.4cm x 10.8cm )

Pressed clay dry weight size:

Length/height: 9-1/2″ ( 24.2cm )
Width: 4-3/8 ( 11.0cm )

Fired weights:

#1: 7.00#
#2: 7.30#
#3: 7.40#

Fired size:

Length/Height: 8-15/16″ ( 22.7cm )
Width: 4-1/16″ ( 10.3cm )

I come up with a net shrinkage of 1″ in 10″ rounded out, and a loss of about 0.70 pounds from bone dry to fired, but actually the pieces started out around 10.50# which means about 3.30# of water and organic materials out of 10.50# are evaporated and burned out in the process, roughly 32% weight loss and 10% size loss.
