Description:Thrown into the perspective of a micro-world again, just near the vegetable counter in Tesco. The polarised ligh shining through the starch grains of a humble potato (variety Estima!) lets them glow like jewels. The offset black cross in each illuminated grain is typical of starch and reflects the circular nature of the crystal layers within the starch. Cooking dissolves the structure and the colour effects and cross disappear. |
