Dear Mr. Willoughby & All,
This is Michael Knight at Castaldo.
We make a two-part RTV silicone rubber putty called QuickSil that
you mix by hand, make an impression into with a finger or anything
else, and let cure for 15 minutes. The result is a permanent,
flexible rubber mold suitable for pouring wax into 1000’s of times.
Or you can mold PMC or ART clay into it, too.
You can read more about it at:
While it was designed for making standard rubber jewlery molds, I’ve
seen people copy picture frame moldings, stone carvings,cast iron
fence railing designs — anything – even tire tracks in hot
I’d be happy to send you (or anyone else out there interested in
trying it) a small free sample to experiment with.
If you’re interested, please give me your complete shipping address
– no P.O. boxes, sorry – and your phone number. I won’t call you,
but UPS sometimes demands that info.
