CHARCOAL BIOLEATHER
"Activated charcoal is one material that seems applicable because of its ecologically sound and purifying properties. It is essentially a form of incredibly microporous carbon, processed from natural carbon-rich materials by applying various gases or chemicals to burn in tiny holes and thus exponentially increasing its surface area. The result? A material that can efficiently filter out all manner of impurities and toxins. Bioplastics present themselves as an excellent and similarly sustainable substrate for activated charcoal with a wide range of uses" Clara Davis

casting sheet
RECIPE
Method:
-
weight your ingredients
-
grind the activated charcoal
-
bring the water to the stove
-
add the gelatine and wait for it to dissolve completely
-
add the glycerine
-
add the activated charcoal
-
simmer and slowly stir the mixture between 60-80 degrees Celsius for 50 minutes until like a syrup
-
Need attention: longer cooking time allows more water to evaporate and as a result it will shrink less during drying so make sure it is still liquid enough to pour.
-
when casting big sheet you need to be fast in pouring the mixture in order to make sure you are covering all the surface.
