I cast silver into the sand box (on the right) which has been drying for over a week. If the sand is damp the silver spits because the steam gets into it, not fun.
I heated the silver to 1026 degrees – this picture shows the ‘button’ – the silver cooled in the funnel into the sand mould.
When the metal cooled I opened the two-part mould and checked that the casting had worked (it has) The holes are to let the air escape as the metal is poured in.
This is a side view of the piece, showing the button/funnel to the right. The spikes are more air escape holes, mainly in case there is steam trapped when you pour metal in.
So that is where this piece is up to. Tomorrow I’ll post pics of the piece with the sprues and button removed.
I hope that it will be cleaned and ready to admire by Open Studios this weekend 21/22 May.
