Porcelain is a ceramic material, and because of this, the question "devolves" into something akin to, "Is a ceramic light socket better than a ceramic one?"
Connect the ground wire to the metal box.
It's supposed to be non-conductive yet it transfers heat. Dielectric grease is often used with a heat-sink to transfer the heat better and it can also be used in applications where electrical components might get damp and/or hot and corrode. Most auto manufacturers are using dielectric grease or other grease compounds to protect light sockets and other electrical connections.
Plug a lamp into a working socket of an outlet to ensure the lamp works. Then turn off the switch and plug lamp into all outlet sockets, top and bottom outlets until the lamp doesn't light. Then turn on the switch and the lamp should light. Often a switch in a bedroom is only connected to one socket in a duplex outlet. It is possible to remove a jumper in an outlet to isolate the sockets for just this purpose. Often an electrician will install the outlet upside down (The third prong pointing up, to identify the outlet.
Dielectric grease would be a better choice.
If you are referring to a porcelain or plastic ceiling light fixture most do not have a place to connect the ground wire. You cannot ground these type fixtures. Just connect the ground wire to the mounting crossbar and forget about connecting it to the light itself. It is on the ceiling and will never be touched unless you change the bulb and then you will have the switch in the off position. It is perfectly safe.
The use of the words porcelain and ceramic to describe tiles is somewhat confusing as most are described as ceramic, then divided between porcelain and non-porcelain. The main differences are that porcelain tiles are denser, smoother and more impervious to moisture, whereas ceramic or non-porcelain tiles are softer. Therefore porcelain tiles are more suitable for areas that get harder wear.
The different types of light sockets available in the market include screw-in sockets, bayonet sockets, pin sockets, and twist-lock sockets. These sockets vary in design and compatibility with different types of light bulbs.

what is the difference between plug ang socket?
The main difference between e11 and e12 light bulb sockets is their size. E11 sockets are smaller and have a diameter of 11mm, while E12 sockets are slightly larger with a diameter of 12mm. This means that E11 bulbs are not compatible with E12 sockets and vice versa. It is important to check the socket size before purchasing a light bulb to ensure it will fit properly.
The different types of light bulb socket types available in the market include standard screw-in sockets (E26/E27), candelabra sockets (E12), bayonet sockets (B22), and pin base sockets (GU10, G9).
The different types of sockets used in recessed lighting fixtures include screw-in sockets, pin-based sockets, and twist-and-lock sockets. These sockets are designed to hold different types of light bulbs securely in place within the fixture.
Bulb holders are commonly referred to as "light sockets" or "lamp sockets." They come in various types and sizes, designed to accommodate different light bulb bases, such as E26, E27, and GU10. Light sockets are essential components in lighting fixtures, allowing for the connection of bulbs to electrical circuits.
Bulbs are things that are plugged into light sockets, and they light up when the electricity is turned on.
