hearth / fireplace tiles- different from other tile?

[diyfromusa]

Hi,

I am tiling a bathroom and have a fireplace inside of it.
The fireplace is a solid cast iron combination fireplace. It is a wood burning fire.

I need to know if I can tile up to and under the fireplace surround with ordinary tile such as porcelin.

In stores I see granite hearths being sold, and I am told that with woodburning fires it is better to use granite tiles- but do I have to use granite? It would be much better for me if everything matched.

PS I would be tiling into the base of the builders hearth so that everything looks uniform.

Thanks for replies from people who have had to deal with this.

Very high temps are used in the process of making tiles/porcelain

They will be fine in you surround.
