A quick Google search shows a common stone Mortar & Pestle sets from Indonesia are carved from volcanic rock. By its color, I would say it is not basaltic rock but it is mostly likely an intermediate volcanic rocks such as andesite, dacite, trachyte, or latite. A careful microscopic examination would be needed to determine the rock type. You would need to know what region from Indonesia to pin down the location to aid in the rock identification.

  • $\begingroup$ Probably correct. Also, since Indonesia is in a volcanic arc and continental settings, it's more likely to be andesite (etc) and not basalt. $\endgroup$ – Gimelist Sep 24 '17 at 11:09
