Supported Charge Store
The hieroglyph for a supported charge store is a milk pot with a carrying net.
Milk is used to describe the nourishment of the cosmos, electricity. Electric nourishment is delivered to Stars and Planets via the female deities Nun, Isis, Maat, Nut, Hathor and Neith. The females are often shown with their breasts exposed to explain their roles as the providers of electric nourishment, together they define the circuitry of the Universe that links Planets, Stars and Galaxies.
The milk pot is a store of milk, thus defining a store of electric charge. The loop is the support.
For this reason the hieroglyph means a Supported Charge Store.
