Chemical etching can support rapid prototyping, deliver precision without introducing stress and work across a wide range of materials.

Using a copper sulfate solution, we can etch glass with a pulsed laser like the relatively common Nd:YAG fiber lasers. The CuSO4 solution absorbs laser pulses, vaporizes and forms copper oxide on the ...

Expert DIYer April Wilkerson shows how to patina copper for a unique and aged metal finish. Lionel Richie calls marriage breakdown ‘scandal of my century’ ...

Copper smelters once used iron oxide to refine copper, unintentionally advancing the path toward iron metallurgy. Research conducted at Cranfield University provides new insight into the shift from ...

The Etch A Sketch was never supposed to meet a Raspberry Pi, a camera, or a mathematical algorithm, but here we are. [Tekavou]’s Teka-Cam and TekaSketch are a two-part hack that transforms ...

The story begins at Kvemo Bolnisi, a smelting workshop perched on a hillside in the Caucasus. Soviet archaeologists first dug it up in the 1950s and immediately declared it one of the earliest iron ...

For over a century, one of chemistry’s most important reactions has kept a secret. The Ullmann reaction, first discovered in the early 1900s, is widely used to link together molecules, helping ...
