====== Week 4: Bio dyes & biofabrics ======

This class will focus on exploring material and coloring alternatives to the current ones. Ranging from natural dyes, using pigments and bacteria, to material biofabrication. Local recipes of DIY materials

====== Natural Dye ======

Efficiency has been proved because of the **absence of toxical mordents**, the **dyeing in a record time of 1 hour**, with a **cold cycle of dyeing**, **without waste** and **recycling the 100% of water**.\\
The raw materials are sustainably proven, with no toxicity, coming from renewable sources.I choose to dye **linen** and pick the variety of different fruits and vegetables. And also I pick three different mordants to see differences in colors.

Materials That I used;

|**Dye Materials**   |**Mordants**   |**Fabrics**   |
|Dry roses |Alum |linen |
|Mulberry and strawberry |Salt |viscose |
|pomegranate |Lemon |  |
|red onions |  |  |
|Cabbage |  |  |
|  |  |  |

====== Crafted and grown material ======

This week as an assignment ı wanted work on **Gelatine based bio-material** and **kombucha.**

Please visit my Week8: [[http://wiki.textile-academy.org/fabricademy2017/students/bio-machine|Open Source Hardware: from fibers to fabric]] assignment to see my experimentation with bio-plastic

===== Gelatine based bio-material =====

{{:students:ayseesindurmaz:biomaterial:biomaterial.jpg?nolink&1200x800|biomaterial.jpg}}

I wanted to make Gelatine-based biomaterial.Gelatin is a virtually colorless and tasteless water-soluble protein prepared from collagen and used in food preparation as the basis of jellies, in photographic processes, and in glue.

When ı was doing my assignment ı was in **Turkey. ** My main aim to my and object from bio-based material that ı can use later on as a product. That's why the material that ı will do should be strong and long term used. I went to **spice bazaar **to looking for fibers. And also visited chemical stores in Turkey which they have a real variety of chemicals.

I bought materials that ı can use as fibers to hold my material. I prefer dried rose which smelling beautiful and wool yarn.

Then I choose my mold from the market.

==== Mold uniververse from Turkey: ====

{{:students:ayseesindurmaz:biomaterial:img_7113xx.jpg?nolink&500x666|img_7113xx.jpg}}

After ı bought my materials ı decided to make **earrings** with my seashell molds.
===== Make Earring from Bio-Plastic =====

|**Material**   |**Amount**   |
|Gelatin |x |
|Glycerine |2x |

I **did not use** water. Because ı want my material as possible as flexible like jellybeans.

//''A gelatine/glycerine based bioplastic with a very low level of glycerine\\
produces a hard, rigid plastic for creating solid objects.\\
Less glycerine: Hard, more brittle\\
More Glycerine: Soft and flexible\\
Too much: Sticky and slimy'' (1)//

How much you use water;

  * Required more time for dry
  * Less flexible.

==== Process: ====

  - Pour 2x glycerine into a coffee pot
  - Heat slowly in a pan
  - Add gelatin slowly, stir until it became totally yellow color.
  - When it's ready it would be dark yellow and really sticky. (İf there is a still white gelatin powder in your mixed it means not ready yet.)
  - Drain liquid to your mold slowly.

===== The gelatin-based biomaterial is smelling really bad while in process. =====

First I pour my material into Mold.

You //do not have to use//  any silicon spray. 3 Days later my earing were ready.

===== Adding fibers into Bio-Plastic =====

I wanted to add also different fibers into bio-plastic.

  * Wool yard
  * Dry rose

===== Making Kombucha =====

For kombucha leather, ı used the recipe from [[http://wiki.textile-academy.org/_media/fabricademy2017/classes/biofabricating_materials.pdf|here]] **page 24**

^Material ^Amount |
|Black Tea |1 lt |
|Sugar |120 Gr |
|Scoby |1 |

===== \\ Process: =====

  * Brew the black tea in a pot. Pour into a clean 1 lt jar when in almost room temperature.
  * Add sugar
  * Stir till all sugar melt
  * Add scoby
  * Wait 10 days.

kombucha is taking shape of your good.

İt was really easy to produce kombucha. I did not expect that much good result.

Scoby is basiccaly eating sugar inside of the black tea
