co2 maker
this is my way of applying co2 to set sodium in sand. Lite a candle or a piece of paper in a container set lid and leave it for about 15 min it sets core to usable/
core mix
not knowing how to mix sodium silicate, i mixed it 3 parts water to 1 part sodium ,then i mixed it to sand a little dryer than green sand semed to work.
