Increases in porosity can increase light refraction, diffuse reflection and scattering, resulting in a brightening of the material's surface. Besides the physical changes, chemical differences compared to the bulk medium may be involved. Because of increased gas–solid interfaces which result, for example due to selective leaching processes during burial, surfaces of ancient ceramics can appear brighter than they originally were. This has to be taken into account when categorizing and discussing archaeological ceramics. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Espresso crema effect」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
