The valence electrons are added to d orbitals in the case of transition metals (or d block elements).
Glass color is added during the manufacturing process by incorporating metal oxides or other colorants into the molten glass mixture. Different metal oxides create different colors in the glass, with cobalt oxide producing blue, chromium oxide creating green, and manganese oxide yielding purple, for example. The amount and type of colorant used will determine the final hue of the glass.
Most transition metals form coloured compounds so they can be used in pottery glazes of various colours. E.g weathered copper which is green hope it helps

Ceramics can be glazed by pouring, brushing, or dipping. Brush on glazes are usually mixed to a slightly thicker consistency than those used for dipping, but its the same glaze, just less water added.
Essentially SiO2 - Silicon dioxidewith added oxides
Its a transition flavor, created between batches with no dye added.

Yes, as long as the glazes are meant to be fired to the same cone. Putting a cone 6 and a cone 10 glaze on the same pot would not be a good idea. But putting two, three, four, etc. glazes of the same cone on one pot is perfectly fine. Just understand that glazes may be stable by themselves, but when another glaze is added on top that may create instabilities such as crazing or running. The biggest problem I have had with combining glazes on one pot is running. Just make sure to put the pot on stilts or on a waste slab so you don't have to grind glaze off the kiln shelf.
The transition metals
Different metal oxides are added to glass to create various colors. For example, iron oxide is added for green glass, cobalt oxide for blue glass, selenium for red glass, and manganese for purple glass. The specific oxide added will determine the color of the glass.
