you could carve your master out of polystyrene or a mix of poly and wood, fill a large box with fine sand make a negative shape with the poly. master and fill the resultant hollow with cement..It will probably need polishing when you take it out. I have seen a dinghy hull made this way.....except he did not use concrete (duh)

You can create a fiber glass form out of the plug or the form you are trying to replicate.

I am not familiar with the "ingredients" of synthetic stone, but I know it exists. Sorry I am not of more help.

It is simply a mixture of sand, gravel, cement and water... Are you willing to go the extra mile since you suggested a site that is closely related to waht I intend to produce? kind regards.

If it's polygonal in shape, wood+plywood combination as mold is a good option for casting cement. However, with curves, it's a lot trickier to carve out the mold shapes. Small scale concrete/cement casting uses wood since it cheaper, and it helps absorb water from the cement mixture quickly.

There was this one old book I remember reading a while ago on this subject. I cant remember all of it, but I think the main principal for making cement castings is to fill a box with plaster of Paris, and then suspend the item that you are trying to cast in it. After the plaster dries you pour the cement into the cavity. You might be able to find a book on the subject here http://lindsaybks.com/
