Learning foundry work is an usual activity for schools so Year 9 Design and Technology students have been making the most of the opportunity. Student first create a ring design out of wax. The wax allows them to do intricate carvings and designs. The wax rings are then encased in plaster of paris. Silver is heated to 1,120 degrees in the school's furnace and then poured into the plaster of paris mould melting the wax and filling the void.
Once set the students then need to examine the rings. Some don't work so it's back to the beginning. Rings that form correctly then need to be polished and possibly reshaped.
