Hard vitreous and non-vitreous kernels
Description
Hard-vitreous kernels are kernels that have a natural translucent colouring which is an externally visible sign of hardness. Kernels that have a starch spot of any size are considered to be non-vitreous kernels.
The following images show kernels that have been cut in half to allow a view of their interiors.
