史前的冰川運(yùn)動(dòng)，一望無(wú)際的冰河終日冰冷，巨大的板塊遷移、撞擊蘊(yùn)含的力量摧枯拉朽，這啟發(fā)了PETRA的誕生。史前冰河打磨遺留的痕跡，與數(shù)十萬(wàn)年的日曬與雨淋，使PETRA兼有如沙粒般的的光潔，與如花崗巖般的粗糲質(zhì)感。

PETRA was inspired by the prehistoric glacier movement—the endless glacier, the huge plate migration with great impact. Prehistoric glacier’s grinding, and hundreds of thousands of years of sun and rain, led to PETRA being as smooth as sand grains, and as coarse as granite texture.
