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

Crafted and grown material

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

Please visit my Week8: Open Source Hardware: from fibers to fabric assignment to see my experimentation with bio-plastic


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:



After ı bought my materials ı decided to make earrings with my seashell molds.

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

How much you use water;

  • Required more time for dry
  • Less flexible.


  1. Pour 2x glycerine into a coffee pot
  2. Heat slowly in a pan
  3. Add gelatin slowly, stir until it became totally yellow color.
  4. 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.)
  5. Drain liquid to your mold slowly.


First I pour my material into Mold.


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


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

  • Wool yard
  • Dry rose



For kombucha leather, ı used the recipe from here page 24

Material Amount
Black Tea 1 lt
Sugar 120 Gr
Scoby 1
  • 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
