Basalt Concrete

[john.h.cox]

I want to produce some of the above but the refiner which it states is needed doesn't give me that option just three others but not basalt concrete. Can anyone please tell me what I'm missing, something quite simple probably, thanks.

Some of the recipes will only appear once you have collected some of that ore. Other you may have to use the Material Analyser to obtain additional recipe for the higher end stuff.

The Basalt is pretty easy to find. You just need to go off and explore.

Thank you both, I didn't realise that it was a separate material thought it was produced from something else. Thanks again.
