$Photomicrograph of clear to brown, bubble-bearing melt inclusions (up to ~110 x 110 µm) in pyroxene from Mount Edgecumbe rhyolite sample 82ARj136. Also note two embayments (one narrow and one wide) protruding into the crystal along the lower edge. Crystal picked from 250-500 µm size fraction of crushed lapilli-sized pumices.$
