The ideal wok

The same material that insulates so well in one dimension (especially discontinuous origami), is the best available thermal conductor in the other two dimensions[21].  The slick, non-stick surface of curved kish will be useful in frying pans.  The traditional Chinese wok will be the easiest cooking implement to manufacture in oriented graphitic form:

Let's not forget the electrical anisotropy of graphite[22].  While we could use a compact flame on the bottom surface of this wok to produce a fairly uniform temperature across the top surface, ohmic heating will produce even better results.  If we apply biased electrodes to top and bottom surfaces of the wok, we can expect the top and bottom surfaces to be approximately equipotential and current through the wok to be more uniform than the heat we could introduce with a flame. 


The current procedure for curved kish synthesis exploits surface tension to make curved melt surfaces that serve as templates for curved kish shells.  This procedure, slightly modified, can produce objects like a miniature "chalice".  To make larger objects, like a useful wok, we can borrow a trick used by modern telescope makers.  Liquid in a dish spinning at constant speed has a paraboloidal top surface, which is ideal for telescope mirrors, if the liquid happens to be mercury or molten glass, and about the right shape for a wok.  If we spin a dish of carbon-saturated molten iron, the paraboloidal top surface can serve as a template for the precipitation of a graphite crystal bent to form a good wok.
