As an exhibit for a design exhibition, we want to create objects from mycelium, that vary in material characteristics. We hope to show, that it's a versatile process that makes different properties possible.
As I've read, the species doesn't influence the outcome too much, it should primarily match the substrate. Also, I guess we want to make grow conditions perfect for the mushroom, s.t. it grows through the substrate completely and to avoid contaminations. (Please correct me if I'm wrong!)
So I guess we will mostly play around with substrate and additives.
Substrate matter: Our first try was with soaked/welled rye which produced a very brittle material (whereas it was not fully grown-through). I imagine hemp fibers to produce something rather strong. There are many many options here, difficult to predict what will happen.
Substrate fineness: I would think that fine substrate gives a more rigid object, whereas it could be possible to achieve flexibility (at least in one direction) by using long fibers.
Additives: Maybe adding oil makes the material elastic? Maybe adding cut rubberbands will? Maybe its possible to add iron fillings to make it really heavy. Fire/Water resistance is something that many people are investigating, maybe we can also collect info about that here.
- What else?
I would mostly like to stick to the hard material mycelium process but maybe kombucha/bacterial leather can be a good replacement for us for the exhibition in case the results are not so spectacular.
@Leen I've seen you made experiments with various natural materials. Did you notice any differences in physical properties?
@Elise Thanks for sharing your library, I have a lot to read
I'm glad about any hints, ideas, experiences, thanks already!
