The mirror is made from a copper-tin alloy with trace elements. To this day, the composition remains a closely guarded secret, passed from one generation to the next. It is believed that keeping an Aranmula kannadi in the house brings prosperity and luck to the owner. For this reason, it is given as a gift during weddings and housewarming ceremonies.
In plane mirrors, light travels through the glass and back, so it gets refracted and changes direction. This can cause aberration or distortion of the image, and this distortion can vary depending on the quality of the reflective coating. In the case of the Aranmula kannadi, the light does not penetrate into any refractive medium like glass: The reflection is on the top metal surface.
