Making Japanese Gold Leaf

Making gold leaf is the signature handicraft of Kanazawa. Pieces of a specially prepared gold alloy are passed through rollers that press them to a thickness of about 0.01 millimeters. The sheets of gold foil are placed between pieces of paper and stacked, and the stack is pounded to spread them and make them even thinner. The sheets are meticulously transferred to another stack of paper and pounded again. This process is repeated thousands of times, until the sheets have been thinned to 0.001 mm. Further pounding reduces the thickness to 0.0001, at which point the sheets are finally ready to be used as gold leaf. This material is so light that it is blown away by the smallest breath of air. Skilled workers handle it with a set of traditional bamboo implements. The final step is to cut it into squares of various sizes and mount it on sheets of mat board. From start to finish the process relies on the work of artisans specializing in particular tasks.

Medieval women created manuscripts too

Medieval women created manuscripts too

Scientists have discovered small traces of blue lapis lazuli in the teeth of a female skeleton from a medieval grave in a German monastery. “The team studying the skeleton concluded that the woman, who was aged between 45 and 60, must have been a painter who frequently licked the end of the brush whilst painting.” “The woman was thought to be part of a group of about 14 women living at the monastery who were likely to have been wealthy, upper class, and educated.

Green Gold

CSIRO Green Gold

Australia has produced its first green gold. Cyanide is not used in the process, even though it is used in 90% of gold produced in the world. Cyanide-based infrastructure usually costs about $30 million, but this new technology costs only about $2.5 million.

 

3.4 tonnes on a runway in Siberia

Gold created by two colliding neutron stars

Gold created by two colliding neutron stars

Gold is created by colliding supernova. They generate sufficient heat to create this heavy element. But scientists have just discovered two colliding neutron stars – and they witnessed this collision from a range of astronomical devices on Planet Earth.

” … this single collision produced an amount of gold greater than the weight of the Earth.”
