Final assignment, Fabric Curvature

I made an attempt to capture different stages of a fabrics deformation or stretching. With a series of casts showing the changing curvature of the fabric when stretched to a predetermined point.

I used the same fabric for all molds together with identical frames and attached the center point of the fabric to a base and then lifted the frame to a specific height. The idea was that this would result in different curvatures.

I was also interested in the point where the curvature moves from being convex to concave.

The result has unfortunately not yet been very successful due to two casts with a bad mix. The casts which i have done so far has given me casts which are very porous and keeps breaking up.

Assignment 5

Our ambition was to cast a a low cylinder shape or a circle using just a few plastic bags. With one inner bag filled with fine sand to act as a the cylinders inner form giver and outer bag to hold the actual cast. The two bags were placed in a bucket filled with sand to act as the cylinder outer form giver.

The cast. A cylindrical form with two “free” plastic influenced surfaces.

Assignment 2, Group 1

mix 1

250 g cement

125 g sand (0,5 parts instead of 3)

100 g water

 

mix 2

250 g cement

750 g sand

25 g water (0,1 parts instead of 0,4)

 

mix 3

250 g cement

750 g sand

100 g water

0,25 g blue pigment (0,1% of 250 g cement)

 

mix 4

250 g cement

750 g sand

100 g water

0,25 g red pigment (0,1% of 250 g cement)

mix5

250 g cement

750 g sand

100 g water

0,25 g black pigment (0,1% of 250 g cement)

 

mix 1

The mix was very liquid, and made a strong smooth shiny sample when hardened.

mix 2

The mix was very dry. It was like wet gravel, and we could not pour it into the form but had to press it in. When hardened it was very fragile and broke when removing it from the form.

mix 3-5

The mix was wet, slow flowing, in consistency. Became hard but with a rough texture when hardened.

Due to the low percentage of pigment and low mass of concrete it was really difficult to meassure the correct amount of pigments. The low percental amount of pigment also made the change of colour almost unseeable. (From the 3 group members one could spot a difference of colour between the samples, 1 could not spot a difference and the third was unsure.) Could also not notice any difference between the three mixes in terms of consistency or texture.

 

Concrete embryos in wax

Group 1, Assignment 3.

Inspired by the random organic shapes created by metal-in-water casting, we wanted to see if something similar could be achieved with concrete. We carried out three tests where we would pour concrete into liquid wax, a medium with higher viscosity than water which we thought would suit the slow-stiffening nature of concrete. Would the wax allow the conrete to slowly unfold and settle, capturing its fluid form?

Concrete: The basic mix from the assignment was used, adding 2g of red pigment.

Wax: Joel Svenssons Paraffin

Test 1: Hot concrete on medium-hot wax

As it was heated, the concrete turned liquid. We then poured it over medium-hot wax, stiff enough to first support the concrete. As the concrete slowly made the wax melt even more,  concrete shapes and canals started to form. It seems like this happened mostly to the side of the jar where the wax was warmest. The final form is yet to be discovered as it couldn’t be seen through the white wax.

Test 2: Room-temperatured concrete on hot liquid wax

Concrete of normal viscosity was poured into clear liquid wax. As it entered the wax, small sausage-like shapes formed instantly and were stacked into a sculptural pile. A thin skin of white stiffening wax started to form around the concrete, making it resemble fetuses of space creatures (top picture). As the surrounding wax stiffened, we interpreted it as it would help the concrete shape to remain as it was while stiffening.

Test 3: Room-temperatured concrete on hot liquid wax (shaken)

Instead of simply letting it pile up and dry, we wanted to try to move the concrete around while stiffening, perhaps taking new shapes. However, as we shook the jar, the newly formed pile wouldn’t move at all, appearing to have stiffened instantly. Leaving the jar upside-down, we will see if time makes the concrete move a bit further.

The fully-revealed shapes will be presented later.
