-Gelatin is an animal-based ingredient. Some might find it problematic to use resources that requires killing an animal because of religious or animal welfare beliefs. Arguments are also made that as long as there's a meat industry, it is better to use product from the entire animal, including skin and bones. Some might consider gelatin to be a product that comes from a waste stream, but this is considered controversial by others.

+Using plant-based ingredients is not by definition petrol-free. Imagine they have to travel long distances by plane, boat or truck: it takes fuel. Also, the effects of GMO technologies and pesticides can be harmful to the environment and it's worth using knowing the source and production standards involved. If you can afford it, buying organic ingredients is a good starting point.

 ## Material properties
 
 ### Comparative qualities
 
-The biofoam feels like the foam-like packaging materials sometimes used for shipping fragile goods or thick foamy kitchen cloth. It feels colder to the touch and is slightly stickier. The upside shows visible bubbles, but the mold-facing side feels very smooth if the mold had a smooth surface. It somewhat keeps the smell of the dishwashing liquid.

+### Description
+
+A transparent, glossy and very flexible sheet of gelatine-based bioplastic. Slightly sticky.
+
+### Physical form
+
+Surfaces & Surface Treatments 
+
+### Fabrication time
+
+Preparation time: 1 Hour
+
+Processing time: 5-7 days
+
+Need attention: None, just leave it to dry as long as is feasible.
+
+Final form achieved after: 1 week
+
+## Ingredients
+
+* **Gelatine powder - 24 gr**
+	* Functions as the polymeer (so it becomes a solid)
+* **Glycerine - 18 gr**
+	* Functions as plasticizer that bonds with the gelatine (makes it flexible). This recipe has a bit more glycerine to make the foil less rigid. It doesn't have the "crackling" sound as a result.
+* **Water - 200 ml/gr**
+	* To dissolve and mix the polymeer and plasticizer
+
+## Tools
+
+1. **Cooker or stove** (optional: temperature controlled)
+1. **Pot**
+1. **Scale**
+1. **Acrylic sheet** (or silicon mat) for casting. The smooth surface results in a very shiny, transparent foil.
+1. **Spoons** 
+1. Whisk (optional)
+
+
+
+## Yield before processing/drying/curing
+
+Approx. 200 ml
+
+## Method
+
+1. **Preparation**
+
+	- Weigh your ingredients
+	- Prepare the acrylic sheet and find a place where you can leave it for a while
+
+1. **Mixing and dissolving the ingredients**
+	- bring the water to the boil
+	- optional: add natural dye if you wish to use color
+	- add the glycerine
+	- add the gelatine
+	- keep the temperature below 80 degrees celcius while stirring *very very slowly and gently* to avoid making bubbles. I prefer a simple spoon to do this, not a whisk.
+
+1. **Cooking the ingredients**
+
+	- 	Simmer and slowly stir the mixture between 60-80 degrees celcius for 20 minutes. I turn it lower when I get bubbles. You don't want the liquid to move, don't boil it.
+	-  Longer cooking time allows more water to evaporate. You will get a thicker, more syruppy liquid that spreads slower: resulting in a thicker sheet. 
+
+1. **Casting the foam**
+
+	- 	Let the liquid cool for a couple minutes until it gels a little but is still liquid, like syrup.
+	-  Cast onto the acrylic sheet slowly to avoid bubbles
+	-  Pour from the middle and hold still, let the liquid distribute itself
+	-  Let it dry for 48-72 hours at least before releasing. If it feels cold to the touch it is still drying. Patience pays off with these sheets
+
+
+### Drying/curing/growth process
+
+Peel it off the mold after 48-72 hours (enjoy the sound it makes!)
+- Mold depth:  N/A
+- Shrinkage thickness:       30-50 %
+- Shrinkage width/length:    0-10 %
+
+**Shrinkage and deformation control**
+
+Letting it dry up to a week to get to the final form. For storage: keep it flat and cover with baking paper. It gets a bit sticky and can cling onto itself when folded for longer periods of time.
+
+**Curing agents and release agents**
+
+None. 
+
+**Minimum wait time before releasing from mold**
+
+3 days (up to a week is best)
+
+**Post-processing**
+
+Store flat in a dry and ventilated room.
+
+**Further research needed on drying/curing/growth?**
+
+Yes. Casting onto textured surfaces is likely to require a different technique and/or molds that have walls to ensure even distribution.

+## Variations on this recipe
+
+- Add a **natural colorant** such as a vegetable dye or water-based ink (e.g. hibiscus, beetroot, madder)
+- Add **less glycerine** for a more rigid foil
+- **Stiffeners** such as fibres, yarn or natural debris may be added for more structure and reinforcement.
+- **Fillers** such as almond or sunflower oil, can be added to prevent additional shrinkage but might affect stickyness.
+
+## Cultural & ecological information
+
+### Where are the ingredients locally abundant?
+
+Gelatin is collagen extracted from the skin, bones, and connective tissues of animals (e.g. cattle, chicken, pigs, fish). It can be produced almost anywhere, so try finding a local supplier. In the Netherlands, Jacob Hooy sells gelatine made from cow's skin.
+
+Glycerin is a sugar alcohol derived from animal products, plants or petroleum. As such it can be produced almost anywhere. Try to find a vegetable-based glycerine that is produced locally. In the Netherlands, Orphi is an affordable vegetable-based glycerin brand.
+
+Water quality is not of the essence for this recipe. Most tap water will be fine. The PH level of the water might affect PH sensitive natural colorants (e.g. ink or dye extracted from blueberries, red cabbage or other vegetables rich in anthocyanins).
+
+**Needs further research?**  Not sure
+
+### Cultural origins of this recipe
+
+Bioplastic production is older than petrol based plastics. In 1500 BC, people in Egypt were already using glues based on gelatin, casein and albumin for furniture constructions.
