This recipe tells you how to make bio-plastic using Gelatine and other ingredients in your kitchen cupboards – a lockdown recipe.
Step by step method:
- Add 150ml of water to a pan over heat
- I added 6 sheets of gelatine but you should add 3 and allow to melt into water
- I added 1 1/2 table spoons of glycerine but you should add 2 table spoons
- Then pour mixture into a tray, however thick you want it, and leave out for up to 2 days to allow to cool and dry out
In this experiment I looked at making a bio-plastic using gelatine which can be done if mixed with glycerine (for cooking) or glycerol (cough syrup). I’ve added more glycerine and less gelatine to this recipe as I think my outcome was too jelly like and not that stronger, could be broken easily so needed more glycerine to make it more plastic-like. At first I decided to bake it to see if that would dry it out but instead I burnt one of the trays and the mixture just turned sticky and stuck to the tray completely. I then poured more mixture into moulds and put them in a fridge to speed up the cooling process but I think they just need to be left for a few hours to dry out, maybe even a couple days. I would also pour a thin layer out when doing this as a thicker mixture won’t dry out as well. This material is not waterproof but is flexible.
