I purchased some rough fire aagte from ebay. Now here is my question. How do I work this stuff to expose the fire if it is not clearly evident?

Carefully If it has a lot of white chalcedony on the bottom, take slivers off with your tile saw until the brown starts showing through. The part you have to work tho' is the top. I use my 8" diamond 80 grit wheel to slowly remove what doesn't look like fire. Check out the e-book here - www.deercreekgems.com/servlet/the-Cabochons/CategoriesThey are an interesting stone to work. Lee

Careful, if you grind too much off, all you'll end up with is "agate". The fire is a very thin layer. I have some from Jamie that I'm gonna work this weekend.

Frist off get out in the sun with water and look the rough over real well for signs of fire. Then go at it carefully stopping often to look. I find it helps to go to finer wheels and put a polish on to find the fire. T

I got some pieces of what I was told was mexican fire something but was then told that it was called calcedony roses (I don't see any fire in there - they're all milky white stuff)
should there be fire in them there pieces?

I do know that some fire agate cannot be ground into a regular cab without either blowing through the fire or not exposing it enough at all. Those are the ones that you see that are carved instead, to follow the fire. Its usually done with a Foredom flex shaft tool. Hopefully yours are not like that.
Ive seen some sellers that are experienced with fire agate and they will tell you if the lot you are buying will be good for a typical cab shape or if they will need to be carved instead.
