Petrography lower if wholly or partly vitreous. The specific gravity of the more common rocks range from about 2.5 to 3.2. Archaeologists use petrography to identify mineral components in pottery. This information ties the artifacts to geological areas where the raw materials for the pottery were obtained. In addition to clay, potters often used rock fragments, usually called "temper" or "aplastics", to modify the clay's properties. The geological information obtained from the pottery components provides insight into how potters selected and used local and non-local resources. Archaeologists are able to determine whether pottery found in a particular location was locally produced
What Is Life All", "Mystical One" and "Pisces Fish". Joshua Greene, another religious academic, identifies the song as part of its parent album's "intimately detailed account of a spiritual journey": where "Awaiting on You All" shows Harrison "convinced of his union with God", "What Is Life" reveals him to be "uncertain that he deserved such divine favor". The song's second verse repeats what Inglis refers to as the "somewhat confusing promise" from Harrison (in lines 3 and 4) should his love be "rejected": Musically, Simon Leng describes "What Is Life" as "Motown-spiced" and a comparatively rare example of its composer's willingness to embrace
