Hitting the bottle again...

... propane bottle that is.
Some more attempts at Raku today.


Yesterday I mixed some color into my base White Crackle glaze, cobalt carbonate for blue and copper carbonate for copper luster. The pink glaze is the cobalt carbonate. 



It was a nice day for November..


These little cups went first...a couple of them blew up..but I didn't perceive a problem so I continued with more..


 ..with any luck the videos will get better..




I have learned some lessons today and lost some work but I'm excited by the effects that I am starting to get. The tall vessels are all broken..i reconstructed them for the picture. The came apart as I pulled them from the kiln. 






The last four pieces came out better with a much slower ramp to temperature.


The knob on the left blew off in the kiln. That's probably due to the differential expansion where there is a change in thickness of clay (coupled with the fast heating).
