欣賞藝術品的時候，有沒有發覺通常是先留意用什麼顏料和媒介？因為用料可算是藝術品的靈魂。若果材料本身已經有豐富的故事，就會為藝術品增添多一層意義。
Are we supposed to focus on the material or theme of an artwork? Usually it is the material that first captures us because the soul of an artwork lies within its material. If the material itself embodies a theme, a richer meaning would be given to the artwork.
