[CoralPlast]

Hi guys, i have this Na2CO3 bought from a local store, can you tell me if label say something about is purity, they say is "extrapure" but that could be marketing since is a cleaning product.

I can use it for randy's recipe?

I cannot tell suitability from that. It may be fine. But using food grade baking soda and baking it yourself gives a purity assurance.
