Making a pair of Hydrangea Earrings with a Bombay Sapphire Gin bottle. The bottle is cut with a diamond core drill. Slots are cut into the disc with a diamond blade. Steffi shapes the petals on a diamond wheel. Petal shapes. The petals are then slumped in a kiln at an exact temperature, too hot and they blob up, too cold and they don't melt. They are then tumbled for a nice finish. They are then drilled with a high speed air driven diamond bit which rotates at 80 000 revs per minute. A piece of sterling silver wire is heated to make a blob on the end. Tomoko attaches the wire to the petal with no glue or solder needed. Finished at last! Other workshop features Sandblast resist stickers are put on the blanks cut from a wine bottle. The sandblasting cabinet. The finished design, glass Fern Frond earrings. My favorite wheel, an 8 inch 60 grit diamond grinding wheel. This can practically grind through a boulder! Polishing a Sterling Silver bracelet. Karl and Nick hard at work in the metal workshop area.
