Is this type of plaster appropriate for a refractory lining?

This specific casting plaster is only a fraction of the price of plaster of paris and seems to have the same chemical composition i.e. Calcium Sulphate Hemihydrate
I wanted to replicate the "Grant Thomson - King of Random foundry" (https://youtu.be/hHD10DjxM1g) and I was wondering if this plaster when mixed with sand would yield the same result as plaster of paris?
