Kiln dried sand?

[ShanRICK]

At the moment I'm using supreme science chinchilla bathing sand for my robo, but I want to switch since it's so expensive. I know a lot of people use Argos play sand dried in the oven but I'm wasn't sure what the quality is like in comparison. Could I use something like kiln dried sand? (I'm not even sure if that would be any different in quality to the Argos stuff to be honest). Also with kiln dried sand would I still need to bake it again to be extra safe?

If anyone knows any other good high quality sand that isn't too expensive that woluld be really helpful.

Thanks
