Burning of Casein Graphene Plastic

Graphite plastic composite mixture, like carbon fiber with epoxy binder glue. Melting point of casein plastic is 280C but its combustible, like seen in the occasional smoke cloud poofs, among the graphite charcoal mesh. Mixture is about 50% casein and 50% graphite with some percentage of graphene. Burning characteristics is similar to a charcoal lump with random easier burning spots. Melting point of carbon is around 4000C and burning as single atom type is very hard, unless high temperature, like in coal burning, ie its burning resistant in low temperatures. Non-melted non-molded casein graphene chiplets are not very conductive, occasional 500kohm or above.
