We had an amazing time in Ōtautahi Christchurch over the last 2 Sundays experimenting in Sand Casting! This dagger was made by Brigitt, she hand carved the wax model and carefully pressed it into the casting sand. She will then remove the model, create pouring holes and pour molten metal into the mould.
Here is is cast in a mix of 50/50 silver and copper. A very successful pour! You can see the lines made in the sand to allow air to escape and draw the liquid metal out to the edges.
We love sand casting although it is a bit hit and miss, sometimes pours just don't work out which can be really disappointing when you've gone though all the work of making the mould. It's a technique that really lends itself to chunky, heavily textured pieces like these rings Bill made.
