I have a small Gemco coffee pot with no directions. It says "do not use on stovetop",but does not say micro on it either. How do I use it? Pls. help.

I can't answer your question but clearly if there is any metal in the construction of the coffee pot it should not be heated in the microwave oven.

Ceramic coffee pots aren't intended to be heated in order to make the coffee. The coffee is either made in them by adding hot water or made in another utensil and poured into the coffee pot for serving and perhaps kept on a gentle hotplate in the meanwhile. Glass coffee pots are treated in a similar way.

Metal coffee pots and jugs can be used on the stovetop even though it isn't a good idea except for "cowboy coffee" when dry ground coffee is scorched in the jug before pouring on boiling water; steel is best for this.

I have used all manner of glass, ceramic and metal coffee pots and jugs on the stovetop but always using a heat diffuser - two layers of perforated steel with an airspace in between.

A coffee maker is a different thing and must be heated fairly vigorously. I find an old electric percolator is still the superior method of making coffee.
