Re: making cores
- Most sodium silicate cores require co2 to be blown thru the coresand.
Although it will air set by itself just won't get as hard. You will
need some sort of fitting to get a good seal. I've used plastic
funnels pushed onto the co2 hose with foam tape for the seal.
Why not just use linseed oil and bake it or rubber cement? What is
the size of the core you are doing. I've even used petrobond in cores
but you need to be careful with PB cores.
