You can use bisque fired ceramic ware as is for decoration, but you cannot use it for food or drink. After clay has been bisque fired it is dried out and somewhat glassy but it's not completely fired. Bisque ware is porous which means that bacteria can collect in the pores and make you very sick if you eat or drink out of it. Bisque ware is also more fragile than high fired ceramics, it will absorb more water and will deteriorate more quickly. If you've made dishes, I'd suggest glazing and firing them before using them.

depends what for. If it is a piece of sculpture and you like how it looks bisqued, I don't think there will be a problem. But if it is something you handle a lot, it will be clearly more fragile than the finished product because the clay is not properly vitrified. How much more fragile depends on the clay body used and the temperature used to bisque it. I would expect the higher the difference between the temperature the specific clay vitrifies and the temperature it has been bisqued, the more fragile.
However, you don't have to bisque ceramics, you can fire (and glaze) it at the proper temperature at the first firing. It is riskier, but can save a lot on electricity/gas that way.

with out being glaze fired the bisque pot will not thoroughly hold liquids

If it is not painted it should be OK for potting things. ..but the glaze does give it strength and cleanability.
I would probably not use it to eat much on as it will stain easy. It's still porous.

It is porous so it will absorb fluids. I wouldn't use it in the kitchen but maybe for decorative purposes.
