Danni and Hannah dress in protective pigskin leather clothing which is worn during metal pouring. One shall help the pourer (me) and the other shall scrape the slag and impurities from the top of the crucible before we pour.
The furnace is heating up and slowly melting the bronze. In the photo some of the bronze is warming on top. Putting it all in at once takes a little longer to melt.
In the background of the photo the moulds have been dug into the sand to keep them steady and upright, the pourcup mouths are covered with foil to stop sand or dust contamination of the mould.
The pour will happen around 11:30!
Today we are burning out the wax from our moulds. The molochite ceramic coated wax trees are placed in the burnout chamber on its mesh floor with the pour cups facing down. The burner is placed on its port at the back and hooked up to a butane gas bottle. Once ignited the wax melts and falls into a tray of water below, this wax is collected with a large scraper and reused once the water is squeezed out.
Once all the wax is out and stops falling into the water tray the kiln is left for an hour or so to fire the ceramic shells for pouring bronze into.
I am very happy with latest firing! The sifted powder enamel worked well giving good coverage although a little speckled – maybe one more coat….
The other bowl (2nd) has a very strong pattern with one smooth patch that perhaps spoils it slightly….I haven’t decided yet.
After two firings with steel enamel. One has burntout quite alot but it looks good. Tonight I intend to sketch out some illustrations on them to be enamelled tomorrow using jewellery enamels which have a lower firing temperature, I think. The theme may be deforestation…..we shall see.
Right now I am testing my white steel enamel on ultra clean saw blades that I bought for 50p each at a flea market. High quality steel so keen to see reaults of firing!
