Hi, the question is ambiguous. There are conductive plastics (cfr, antistatic bubble packs. these bags/mats have one side which is (albeit with high resistance), conductive) so as to harmlessly bleed static.
Ceramics can have high/very high resistance insofar they are usable as insulator.
Other mixes, or doped/contaminated ceramics can be conductive. A lathe chisel cutting bit can be a ceramic, it is harder than "widia", but it is conductive.
(widia is a sintered metals oxides mix, not a ceramic)
Enamel is a ceramic, and that too is conductive. (you can draw a static spark on an enamel surface on a gas range.)
Static, it can build up to a very high voltage with low potency, it can kill consumergoods like PC motherboards. The person may not even feel it happenned, yet the discharge happened and the component touched cannot dissipate the high voltage fast enough so it dies. (PC components running on 1.5V getting over a 1.000V burst, par example. One should know static can be as high as 80.000V when the person has been wearing insulator clothing.)
See what I mean?
Kind regards, Jaak

∙ 10y agoa ceramic cup has more air trapped than a glass cup so its better insulator because materials which have more trapped air are better insulators.

Is glass a better insulator than styrofoam?
no
Why does liquid heat faster when microwaved in a glass cup instead of a ceramic mug?
Perhaps because the glass is in amorphous structure and ceramic is in crystalline structure. Glass is a better conductor of heat than ceramic is.
Is air or fiberglass a better insulator?
i hope air is better than fibre glass
Is glass a better conductor of heat than plastic?
Glass and plastics are not good conductors of electricity.
What cup will freeze water faster glass or a foam?
I assume you mean the water in the cup. Foam is a better insulator than glass, so it should be the water in the glass cup.
Is glass a better insulator than styrofoam?
no
Why does the glass on a window pane feel cooler to the touch than the wood frame surrounding the glass?
Wood is a better thermal insulator than glass, which is easily cooled.
Why does liquid heat faster when microwaved in a glass cup instead of a ceramic mug?
Perhaps because the glass is in amorphous structure and ceramic is in crystalline structure. Glass is a better conductor of heat than ceramic is.
Is air or fiberglass a better insulator?
i hope air is better than fibre glass
Is glass or metal a better conductor?
Glass has a higher conductivity than thin plastic but,it is still lower than metal so metal may be a better conductor
Why does a double glass window have argon?
Because argon is a better insulator than air
What is the advantage of a glass coffee mug over a ceramic one?
Coffee mugs are usually made of ceramic earthenware materials instead of glass, because materials such as porcelain retain heat better than glass. If glass gets too hot, it will shatter.
Is wood a better insulator than glass?
No. Wood has more air in it than glass, and air is pretty much accepted to be one of the best insulators ever.
Is glass a better conductor of heat than plastic?
Glass and plastics are not good conductors of electricity.
Can plastic cup be replaced by glass beaker in determination of heat of solution?
yes.but plastic cup is a better good insulator than glass beaker.
What cup will freeze water faster glass or a foam?
I assume you mean the water in the cup. Foam is a better insulator than glass, so it should be the water in the glass cup.
Why do people use cooking pot made of metal?
Metal absorbs, transfers and spreads the heat better than ceramic or glass.
