大英博物館さんのインスタグラム写真 - (大英博物館Instagram)「This spectacular bowl from Italy is made of two layers of clear glass with an elaborate gold leaf pattern sandwiched in between. Perfected between about 300 – 200 BC in the eastern Mediterranean, this cut gold leaf decorative technique had spread to Japan by the 7th century. Called ‘kirikane’, it’s still used there today on statues, paintings and lacquer ware. Since 2010, glass researcher Dr Yasuko Fujii and master of kirikane Professor Hidetoshi Namiki have researched ancient ‘kirikane’ glass. 👉 Scroll to see their insights into how each of the intricate shapes on this bowl were made: 🖌️ 1: Cut a straight line of gold leaf and lay the strips on the bowl using two brushes. 🏵️ 2: Overlap pre-cut geometric shapes of gold leaf to create a new design. In this case, two petals for a heart-shaped flower. 🔳 3: Create an outline for a complex shape using a thin line of gold leaf, and then fill the area with larger pieces to create a solid shape. 🌊 4: Carefully bend wedge-shaped gold leaf pieces to create a wave pattern, and then fill. The reconstruction took Professor Hidetoshi nearly one month to complete!
