Curi Basalt
Code Name : Code Name : Light Gray Flagstone
CURI Basalt is also the same type as lavastone which is another extrusive volcanic rock. This CURI Basalt usually comes up with grey to black color similar to Andesite and Candi and fine-grained due to rapid cooling of lava.
The difference, and specialty, of this CURI Basalt is that it has holes all over the surface and even inside the stone yet it absorbs water terribly.
