Branching out trying different styles of photography recently and heres another. Long Exposures during the day, not using an ND filter but Welding Glass for the more DIY/Cheap route.
This is a slightly used piece hence a few marks and was held in position by hand (ouch) to see how it would go.
I will be ordering a few of these I think (not bad for £1.50 a go compared to a normal ND)

Exothermic welding, also called hot melt welding, fire-clay welding, thermite welding and explosion welding, is a high-heat principle that utilizes the redox reaction between metals, the operation of which is simple, easy to learn, safe and efficient, and it has significant results in the production of high quality permanent welded joints between homogeneous metals and metals of different materials and is now well known to the public, becoming more popular in more and more architectural designs, and widely required to replace the connection method using conventional metal fixtures.
Exothermic welding requires high-quality graphite to form a cavity mold with a certain shape, such as line style (butt), T-joint (three-way), cross-type joint (four-way) and so on. The mold can be used multiple times, effectively saving costs.

Remains of studs after i broke them with a bit of roughness and my trusty hammer. Notice how the welds are still intact, breaking on the stud itself.
