蒔繪收納盒
Japanese makie lacquer case
蒔繪是日本漆器工藝的一種,通常以黑漆為底,彩繪紋樣後再於其上撒金銀粉,最後加工研磨製造完成。十六世紀下半葉之後,蒔繪漆盒隨著國際貿易網路的開展而行銷歐亞世界。不管是不是直接受到明末鑑賞家的啟發,清朝康熙(1662-1722)、雍正(1723-1735)和乾隆(1736-1795)三位皇帝經常使用舶來品漆盒收存各式珍奇寶貝。展出的箱子,裝飾著日人稱為「蔦紋」的葉形圖案,裡面可以容納十九個木匣,最初是為了收納七十四件小瓷杯而設計,目前則留存其中的六十七件。
Makie stands for one of the techniques in Japanese lacquer craft. The base is usually coated in black lacquer, with the silver and gold powders sprinkled on top of the drawn patterns, and then completed by fine polishing. After the second half of the 16th century, the makie lacquer box traveled to Europe and across Asia with the development of international trading network. Regardless if the inspiration came directly from the connoisseurs in the late Ming dynasty, the Qing emperors Kangxi, Yongzheng, and Qianlong frequently collected their various treasures with these imported lacquer boxes. The exhibited box is decorated with the “tsuta” pattern named by the Japanese, and with the capacity of nineteen wooden cases. Initially the design was made to store 74 porcelain cups, and 67 pieces from the original set last till nowadays.

蒔絵(まきえ)は、漆工芸技法の一つである。
蒔繪(日語:蒔絵),是在漆器上以金、銀、色粉等材料所繪製而成的紋樣裝飾,為日本的傳統工藝技術。利用漆的黏性,將銀粉或金粉依照想要的圖樣,固定於漆器上的技法稱作蒔繪。「漆」指的是漆樹的汁液,塗抹於器具上,除了可以固定銀粉、金粉,也可以使器具更有光澤。蒔繪的紋樣題材眾多,技法則是隨著時代不斷改良、推陳出新。日本的國寶中有許多都是蒔繪的作品,如《八橋蒔繪螺鈿硯箱》、《片輪車蒔繪螺鈿手箱》等。由於日本在江戶時期或更早的年代,與許多歐洲國家有過貿易往來,在現在一些歐洲國家的博物館亦可見到日本蒔繪的蹤跡,如英國維多利亞和阿爾伯特博物館藏的《樓閣人物源氏物語蒔繪箱》,此件為17世紀日本實施鎖國時,由當時的荷蘭東印度公司向日本購買的作品。

發展歷史[編輯]
日本最早有關蒔繪技術的藏品為正倉院的「金銀鈿荘唐大刀」,年代約在奈良時代末期。在這把唐大刀的刀鞘上可看見金色紋飾,稱作「末金鏤」。「末金鏤」一詞出自《東大寺獻物帳》(日文:東大寺獻物帳):「鞘上末金鏤作。」末金鏤與後來的研出蒔繪相似,且比「蒔繪」一詞早出現,被認為是日本蒔繪的前身。
在平安時代,由於金銀粉的精製技術尚未成熟,此時流行的蒔繪技法為「研出蒔繪」。先前介紹的「金銀鈿荘唐大刀」也屬於研出蒔繪的一種。研出蒔繪的作法為,先塗上一層漆,撒上金粉後,整片繪畫區域再塗一層漆,最後用木炭慢慢磨平表面顯露出金粉層。
