The replica should be made of different material. So it should be easy to kept in cold environment. I think its no need to worry about that.

Mr. Cheng, Thank you for your response. Unfortunately, I don't understand what you said. If you say that the replica should be made out of different material, does that mean that the ones advertised are not good for New York winters? What material could withstand very cold temperatures?

Thank you. Gail Sekler

We have our own reproduction plant,maybe i can give you some ideas.I think this should have some business with the prepared dye and fire technician,moreover,nowdays,more and more customers would like to put them in garden or outdoors,we have to change our prepared dye which used in last procession in order to look original and water-resistant more than before.
All products will be fired by high temperature about 1000degree,they are between porcelain and pottery.high rigidity after fired, which have not finished color can withstand cold,just his outside color maybe can not withstand longtime cold temperature which the main comported is propylene.
How do you think about?it`s my pleasure to answer any question what i known.
