moisture
not nearly as bad as the first one but still not usable. Let the core sit out overnight and it dryed somewhat but not enought. oh well back in the pot and keep trying.

i might have mixed to much silicone silicate in sand , moisture does this to aluminum.

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.
