# Material Sample 1
## Flexible Agar bio-foil 20
### General information[¶](https://class.textile-academy.org/2020/loes.bogers/projects/outcomes/tools_and_templates/recipe_template/#general-information)
The material is flexible, strong and has a smooth texture. It's see-through and good for packaging materials. it's a little sticky.
**Physical form**
Grains & Powders
It's made from Agar Agar. Agar Agar is a jelly-ish subtance made from red algue. And is ussualy used with making desserts.
Color without additives: white/yellow and see-through
**Fabrication time**
Preparation time: 20 minutes
Processing time: 5 to 7 days
Final form achieved after: 4 weeks
**Yield**
Approx. 5 to 7 days
**Estimated cost (consumables)**
*including use of disposables likegloves*
*Pan, dish, mixer, Agar powder, water, gylatine*
### Recipe[¶](https://class.textile-academy.org/2020/loes.bogers/projects/outcomes/tools_and_templates/recipe_template/#recipe)
#### Ingredients[¶](https://class.textile-academy.org/2020/loes.bogers/projects/outcomes/tools_and_templates/recipe_template/#ingredients)
* **Water**
* 250 ml
* Solvent
* **Agar Agar powder**
* 5 gr
* Plasticiser
* **Glycerine**
* 20 gr
* Stickyness and flexibility
#### Tools[¶](https://class.textile-academy.org/2020/loes.bogers/projects/outcomes/tools_and_templates/recipe_template/#tools)
1. **Mixer**
* Is this tool optional?No
2. **Pan**
* Is this tool optional? No
3. **Dish**
* Is this tool optional? Yes
#### Method[¶](https://class.textile-academy.org/2020/loes.bogers/projects/outcomes/tools_and_templates/recipe_template/#method)
1\. First you mix the water with glycerine.
2\. Heat the mix in a pan.
3\. If the the mix is heated you put the Agar Agar powder in the pan and mix it for 20 minutes. Don’t let the liquid boil.
4\. After 20 minutes you can pour the liquid on a suitable plate.
5\. The sheet will be dry within 4 to 5 days.
#### Drying/curing/growth process[¶](https://class.textile-academy.org/2020/loes.bogers/projects/outcomes/tools_and_templates/recipe_template/#dryingcuringgrowth-process)
\[Describe the setup, including details of mold and tools used (e.g. press, breathers, other) and other details pertaining to the process here]
* Mold depth 22cm x 22 cm x 1 cm
* Shrinkage thickness \[20] %
* Shrinkage width/length \[0] %
**Shrinkage and deformation control**
This recipe doesn't shrink in size, only a little bit in thickness.
**Minimum wait time before releasing from mold** 5 days after molding it.
**Post-processing**
Store the material on moisture absorbing paper for a few days for less stickyness and the best end material.
**Further research needed on drying/curing/growth?**
Yes
Maybe trying less glycerine, something like 10 gr.

*Image guidelines: images should be landscape format and sharp. Please provide captions so the viewer can understand the elements of the setup. Include images of the drying/curing set-up*
Variations[¶](https://class.textile-academy.org/2020/loes.bogers/projects/outcomes/tools_and_templates/recipe_template/#variations)
*Which variations can be made with the same recipe? Mention other physical forms, additives etcetera. Provide references if applicable*
* You can make it less flexible by adding less glycerine to the recipe.
* Make the texture less smooth by cooking the recipe less than 20 minutes.
### Origins and references[¶](https://class.textile-academy.org/2020/loes.bogers/projects/outcomes/tools_and_templates/recipe_template/#origins-and-references)
**Cultural origins of this recipe**
Agar Agar is mainly used as a replacement for gelatine in all kinds of recipes.
**Needs further research?** Yes
I don't know about any cultural references.

### Ethics & sustainability[¶](https://class.textile-academy.org/2020/loes.bogers/projects/outcomes/tools_and_templates/recipe_template/#ethics-sustainability)
I prefer to use Agar Agar in my recipes, because this substance is generally easy to get at a
local drug store, a biological store and in food warehouses (Holland\&Berret and Sligro in The Netherlands). Agar Agar is a non-petrol-based alternative that is vegan.
I have created an Agar Agar recipe that is strong, flexible, smooth and see-through. It has everything we love about plastic, but then without the plastic. Once the material has been cooked and reached a stable form (takes up to 3 to 4 days) it can be recycled and reused up to 3+ times. You just heat the substance up and pour it into something of your choice. The material is soluble in water at 80 degrees celsius and can withstand several hours of being exposed to 40 degrees Celsius. It’s a perfect bioplastic bag which you can use, reuse, recycle or throw away responsibly if the material it self is clean.
**Sustainability tags**
* **Renewable**: Yes
* **Vegan**: Yes
* **Made of by-products or waste**: no
* **Biocompostable**: Yes
* **Re-usable:** yes, heat it up.
