Making a cast of the Scraps vase using lab-grown mycelium. The mycelium is grown using a substrate of sawdust, soy husk, used coffee grounds, water and reishi mushroom inoculation liquid. After growing in jars for three weeks, the mycelium is decanted and hand mixed before it can be applied to a mold. Once it has been molded over the target form, it is covered in plastic where it will sit for a week, growing into a solid. The cast is then removed from the form and is left to air dry for another week, before being put in a dehydrator to remove all liquid. Mycelium is 100% natural and biodegradable. Using it as a casting material allows for forms to be replicated with incredible detail without creating unnecessary waste.
