-- Substitute part of the water with a dye
+- Substitute part of the water with a (neutral to alkaline) dye. The PH of the cooked agar mixture is about PH 9-10. Making the mixture very acidic changes the structure of the polysaccharide, resulting in a weaker more brittle bioplastic.
 - Try or design different molds to create big spatial structures and objects
 - Use different fibres as enforcement. Other *natural* fibres may be continuous/discontinuous ([long fibres like yarns](https://class.textile-academy.org/2020/loes.bogers/files/recipes/alginatenet/), strings or hair. Or they can be short fibres that are chopped like wood chips, [egg shells](https://class.textile-academy.org/2020/loes.bogers/files/recipes/biolino/), leather leftovers), particles or even braided and woven fibres like the cotton used here. Collagen, cellulose, silks, and chitin are the types found in nature. 
 - Use a different matrix: biomaterials like beeswax or animal glue for example are thermoformable matrices (the ones you can form with the help of heat). And setting matrixes like bio epoxies, white glue (made of flour), alginate, gelatin and starch-based plastics, mycelium and kombucha.

+- Re-use: the plain agar recipe without additional additives can be melted by reheating it (add a splash of water if necessary), reusing a composite depends on the materials used. This composite can be formed and reformed over and over.
