Inspired by the pattern of the basic type of Wasa hard bread I set out to replicate this using stretched fabric over wooden plugs as the mold lid. The size of the cast sample was 20x10cm, however the concept can benefit from being cast in a much larger scale as this would help abstracting what was the origin of the pattern. A cut-out Swedish scale figure in 1:5, 1:10 and 1:20 was photographed in front of a mock-up wall made of real bread to test the tile scale and capture the beautiful shadow effects.
The basic recipy in the assignment was used. Small cracks between the plugs appeared, because of either too much or too little water according to the teachers.
A picture of the concrete sample will be added soon when it has hardened completely.
When lightning hits an area with lots of silica in the surface material such as sand, the material may fuse and create a lightning rock – known as a fulgurite. The tempereature inside lightning can go up to 30 000 Kelvins (29 700 degrees celsius), instantly melting and fusing the sand.
Most often, the fulgurite is tube-shaped with a hollow interior. The insides of fulgurites are often glassy and smooth, due to the rapid cooling of the fulgurite after being hit by the lightning. If the fulgurite is not tube-shaped, it is called an exogenic fulgurite, which is when the material is thrown into the air during a lightning strike and then melted and fused.
