Materials as a Journey

Since the last blog post I have been studying how human interactions influence materials, surfaces and objects over time.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

These interactions whether small or big, deliberate or indeliberate, over time or all at once, old or recent all tell a story of human interaction. Perhaps it was Jacob’s first grind, or the time Lucy dropped a crate on the grating. Every mark, scratch and sign of wear tells of an event, memories known only to the object itself. Think of the stories they could tell if only they could speak.

 

Thus it may seem materials are more than characteristics, price tags and chemical structures in which they are categorised; no materials are a journey. Take steel for example. Iron is created during a supernova at the end of the life of a red giant. It is expelled into space along with other elements before collapsing under the force of gravity to form the sun. The remaining material including some iron begin to clump together under their own gravitational force to form proto-planets, including Earth. This iron embedded into the rock and suspended in the ocean reacted with other elements to form hydroxides, sulphates and more. However 2.8 billion years ago the emergence of oxygen producing cyanobacteria and halobacteria allowed those hydroxides and sulphates to be displaced to form iron oxide, forming layers of iron rich sediment. Ancient seas would disappear to allow humans, eons later to mine the iron ore. From there together with coke and lime the ore is processed into pure iron. Oxygen is then blown into molten pig iron to form steel. Steel from which we use to build our buildings with, go to work with, eat our food with… without for a second paying appreciation for it’s celestial origins.

 

As an initial experiment I took a computer keyboard painted it bright orange and painted removable chalk paint on top. The idea is over time different users’ iterations will wear away at the keys differently, thereby mapping their usage, preferences, profession… and more. Through the scope of wear the keyboard can speak and tell of those stories we do not even think about in our daily lives. However, I have found the chalk material to be too difficult to work with, they crack and require several coats at which point hey become too thick. Furthermore, the chalk paint hides the key symbols. After some research into materials such as thermochromic paint which changes based on body heat, I found printable temporary tattoo film to serve this function perfectly.

 

First however, I needed to test the feasibility to see whether usage actually does vary based on use case. Below are two heatmaps of my keystrokes on two different days. On the first one I was using Photoshop extensively thus the Alt (for navigation and shortcuts) and Ctrl (I was doing a lot of clone-stamping) keys were used the most, on the second one the alphabet keys were used the most due to writing a lot of text. This kind of deviation in usage could possibly represent the difference between a graphic designer and a historian for instance.

 

 

 

 

 

 

 

 

 

I envision making a number of these wear away keyboards to send out as probes after which usage patterns of different groups such as: designers, business-people, accountants can be mapped and used to draw certain insights. From which there are many totally different avenues I can think of to take, but I am completely lost at the moment.

Passing light through the spiral

22/10/18 – blog post – Passing light through the spiral – Matt copeland

Plywood acrylic composite –

 The last two weeks have been mostly material research. Last week I started with a composite – plywood acrylic plywood – material and had laser cut the spiral design allowing the 2d to 3d movement. The layers bonded well with a spray contact adhesive even after being laser cut. I hoped the clear acrylic layer would transport light up the spiral creating an even glow as the spiral was pulled from the rest of the board. In darkness the light was obvious on the first ring of the spiral but limited when passing any further up the coil and in light or partial darkness it was hard to identify the light. In the darkness the light was impressive when the spiral is pushed inwards. A bowl of light is created and there is an impressive transformation as the two-dimensional panel shows little to no sign of any light until interacted with. I tried a lamination of mirror surrounding an acrylic centre. The mirror was meant to direct the light inwards and towards the end of the coil. This didn’t work as any glue I used stopped the light passing from the acrylic to the mirror layer. The layers also didn’t bond together well.

Electro luminescent wire –

In Wednesdays studio class Geoffrey Mann showed me an alternative lighting source, electroluminescent wire. The wire has a phosphor centre that glows when electrically charged. It can be bought in many different colours and in strands as thin as 1.6mm (Castle, 2018). I bought a few lengths of the wire at 2.5 mm and a battery pack to power them then began designing a means of housing the wire within the coil.

Process to embed wire –

Because the acrylic wasn’t passing the light up the spiral in the way I wanted I had to consider other ways. I began experimenting on the laser by first drawing a spiral that had a void cut out of the centre to house the EL wire. This was unsuccessful as it meant post cut lamination and the sections warped on the laser when so many cuts were made so close to each other. I did some engraving tests and realised I could engrave a channel to house the wire rather than cutting. This would leave the acrylic solid long enough until the final spiral was to be cut, and I could also have a layer of plywood pre laminated then engrave and then cut both layers without worrying about lining all three layers post cut. I have experimented with power and cutting speed on the laser in order to cut the correct depth in the acrylic I worked out that at 100mm/s speed and 10 mAh of power, I could cut 1.5mm deep. For the 2.5mm wire I had, I would need two passes. On small test pieces I experimented with the engraved channel being cut into the wood rather than the acrylic layer. The MDF I used to trial this engraved better than the acrylic and more material was removed in one pass. It was difficult to achieve the correct depth without breaching the thickness of the material when working in such small margins. This test piece in the end, worked and the light was even and bright inside the coil. The MDF was fairly weak though and on such a small scale and with glue residue from the post cut lamination, the spring motion is non-existent. Although the engraving of the acrylic is time consuming it is a better option. The material is stronger when leaving thin walls and the light is more vivid when the EL wire is at the core of the lamination layer it will be released from.

Movement –

I spent some time during the week researching materials that could potentially at movement to my object. I was hoping to find a material that could be laminated into the composite I had, be laser cut and when electrically charged – like the EL wire – react and move. I had a rough idea of this being done before in things like artificial muscles but didn’t know the exact name. I did some online research looking for electro reactive materials. There is a lab at Columbia 3D printing a synthetic tissue. (Shah, 2018). These materials are difficult if not impossible to acquire.Geoffrey Mann suggested that the most important part of the product and tests I had designed was the interactions with the materials and the motion of the spring. Tests with the first acrylic lamination showed that the interaction turned the light on and off and perhaps contact with the object is more important than having it move by itself. The interaction could also be the activation.

Spiral –

the spiral I designed is the same width for the whole length of the coil this means there is an uneven spring as the radius of the spiral gets smaller. To combat this, I would have to design a tapered spiral that gets smaller towards the centre meaning less material resistance and more flex I experimented with different cuts on the laser. Although the tapered spiral has an even spring, I feel the motion isn’t as pleasing as the constant width spiral. This would have to be tried on a multilayer lamination to get a true reflection of the action.

Existing design research –

“Unconscious Form” – John Sorensen-Jolink

Sorensen-Jolink’s design is a lighting performance piece photographed with dancers for the series ‘Unconscious Forms” (Howarth, 2018). The curved oblong sections are made from cast resin with imperfections and impurities added to manipulate the light. (Collection, 2018)

“Pocket Light” – Ryan Hark

The 2-Dimensional bank card sized light folds into a 3d form and activates the light bulb shaped clear acrylic part. There is a switch mechanism when the two parts separate.

Gestures and Materiality

As a designer, my passion for technology is both a blessing and a curse. On one hand, it is an interesting and familiar topic where I can focus and hone my skills, on the other hand my obsession with small technicalities has always been a burden on my role as designer to truly see the role of technology; that is to serve people. Inspired by design literature such as The Language of Things by Deyan Sudjic and The Design of Everyday Things by Donald Norman, I have decided to reevaluate design in technology through a more human centred perspective. This initial study lead me to explore different gestures and materiality as ways we can interact with technology in a more meaningful way.

Not long into my research I discovered many of these gestures (pull, turn, squeeze, twist…) can all be found in the recent past. Being a bit of a history buff I visited the Edinburgh Flea Market and The Edinburgh Antiques Centre for inspiration. From there I explored and iterated through making simple prototypes that replicate these gestures.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

However, what I quickly realised was that I was more interested in the evidence of gestures rather than the gestures themselves. Such as the warping on this comb.

 

 

 

 

 

 

 

Theses signs of wear are physicalised data of human-environmental interaction. They represent history, memories and events.

From here I will be exploring how objects change through our interactions or lack of interactions, and how I can apply what I have learnt to rethink our interactions which technology.

New Making Post #3

After toying with the idea of cutting or lazercutting a form from a sheet of neoprene I decided that leather would be a much nicer material to create in (if not to work with). Leather is unique in that it can look simplistic and expensive when new and also ages wonderfully well, telling the stories of its increasing sentimental values embodied by it’s creases, folds and discolouration.

Can I replicate the attachment I feel to old leather boots in my intervention?

When using leather there are always ethical questions that crop up, moral qualms that some consumers will have over whether your product or service will be categorised as ethical design. Re-using old leather, though, pays no money towards livestock industry.This as well as availability to the general public were reasons for my service being built upon recycled belts.

New Making Post #1

 

My chosen New Making problem is water storage during exercise.

My first attempts at solutions were thrown together with whatever was at hand and whilst being quite beautiful in their simplicity and spontaneity were quite ineffective. As the project moved on I began to create more efficient interventions, culminating in a 3D printed object. This is a tiny modified bottle-top that can attach most plastic bottles to your back, it sits well on the body and supplies water via a plastic tube. It is however, uncomfortable due to its rigidity and flops around if moved too much. Would a softer material be more appropriate?

Further experiments

Using the refined method of experimentation the new tests worked! Below is a picture of tests three (B) and four where the mycelium was left to grow in substrates including cardboard, cotton calico and dead leaves. In one test I left the mycelium spawn to grow in between layers of bubble wrap to see how it would take the shape.

Tests three (B) and four

I left test four to grow for 14 days and tests three to grow for seven days to display the different stages of growth in my presentation.

More mushrooms

After some reading and searching around the internet for more useful information I felt I should give it a try. How difficult could it be?

  1. Cut your mushrooms  into smaller pieces to enable best extraction of dye possible.
  2. Put them in a pot with water and bring up to a boil.
  3. Lower the heat and let simmer for a while. At this stage the water should have changed its color, the longer you leave it the darker and deeper the color will be.
  4. Soak your textiles in water before submerging them into the dye. Preferably in the same temperature so that the fibers won’t be damaged. They longer they are left in water the better, it enables the fibers to open up and be more likely to pick up the dye better.
  5. Move textiles from water bath to dye bath.
  6. Never let the dye bath with your textiles boil, let it simmer and leave them until you are satisfied with the look.
  7. Rinse in water and leave to dry.

I have tried mushrooms I found in nature, fresh and dried from the supermarket. Most of the mushrooms I tried gave a subtle and earthy looking dye.

3different2

Many of the mushrooms documented are best extracted with the help of mordants (different salt solutions to change the pH-value of the dye bath which can either bloom or sadden a color). All the mordants I have used have been organic with one exception of soda crystals (pH-value 12-13). The reason for trying to go all organic is because I want to see if it is possible to dye your own textiles with local products and not in an artificial way that will destroy our environment.

A new method

The outcomes from the first tests worked…but not particularly well.  Mould grew on my first mycelium tests and didn’t have a particular structure in the sealed plastic bags. It was time to speak to a professional. After searching high and low I found Dr Patrick Hickey, based at Summerhall, he completed his PhD in Mycology at the University of Edinburgh and has completed many projects looking into the structure of mycelium as well as the bioluminescent qualities of mushrooms (http://www.nipht.com/).Dr Hickey's workspace

He suggested that I need to think about three key components:

1.The type of mushroom mycelium will affect the composition of the final substance and its qualities

  • wood rotting fungus has cord-like mycelium which is tough
  • oyster mushroom has a dense, feathery mycelium
  • some good ones are stropharia aurantiaca and physalacria armillaria (see below).

Stropharia Aurantiaca and Physalacria Armillaria

2. Choosing the substance for it to grow on is important

  • On wood you get white-rot fungi and brown-rot fungi that eat different parts of the tree.
  • White-rot eats lignin which makes up the scaffolding of wood.
  • Brown-rot fungi (like honey fungus or armillaria) decomposes cellulose which is the structural component of cell walls in plant material.

3. The process in which you’re growing the mycelium substance needs to be as sterile as possible so as to prevent other micro-organisms from growing.

  • In order to sterilise things you need to either heat them up so as to kill the bacteria on the surface or spray them with ethanol.

With this new information I have now moved on to work in more sterilised conditions, so as to reduce the risk of contamination. More to follow…

The trip that sparked an idea

When me and Joanna met with Rebecca Yahr at the Royal Botanic Garden in Edinburgh in the beginning of October she showed us many different things that all had fungi in common. The one thing that spoke to me the most was the samples of yarn that had been dyed with mushrooms. I had seen textiles being dyed with plants and other natural things but the thought that mushrooms would do the same thing had never crossed my mind. Intrigued to find out more I bought two books on the subject and started reading to learn more.

Exploring, gathering and testing.

Foraging for mushrooms around Edinburgh I found various types of honey fungus (armillaria), petticoat mottlegill (Panaeolus papilionaceus ) and turf mottlegill (Panaeolus fimicola). Having also bought mushrooms from local shops as well as supermarket chains, I had a collection of eight different types of mushrooms (including varying location of source).  I had three different mediums in which the mycelium could grow: cardboard, dead leaves and coffee grounds.

Documenting their features, where I found them and which medium I was putting them into will help in the future to see differences in the samples.
