granules are tested both uncalcined and calcined at 260°C and 537°C as calcining can often increase rust potential. The particle shape index test was developed to determine the shape of the roofing granules. Roofing granules should be round and cubical and not flat and elongated. Round and cubical
The terms pa hoehoe and aa both originated in Hawaii, where effusive erup tions of basalt are commonq fissures Lava flows do not have to emanate directly from volcanoes, but can pour out of deep fractures in the crust, called fissures, that can be independent of mountains or hills of volcanic origin.
