Heather...Yes. Obvioulsy, it will have to be molded again and you may have to clean up the original a little (they will have to put a release agent on the original). From there all the wax positives will be cast from that mold. I even have an unfired clay piece that is still pretty much intact after the molding process.
You really should start considering casting some of your works in bronze. You're a very talented artist. My suggestion would be to start by pre-selling (what is referred to as a 'pre casting price') and after you have enough buyers to cover your cost of molding, casting and base then do the casting. This is pretty much standard procedure even with artist in large galleries. A foundry can give you an estimate of cost from your original work to give you an idea as to how to price them.
It's not unusual for a precast price for the first 3 or 4 to be lower and as the edition size starts to sell out (thats always nice.
) the price goes up. In some cases astronomically with well known artist.
So..go for it girl!!
If you want to pm me with any questions that I can answer will be happy to do so. You have a good local foundry and the best patina artist that I know (Ron Young) right in your neck of the woods.
