October is Casting Month!

Science Workshop
October is Casting Month!
Hydrospan 100 is a special “englarging” casting resin that swells, on curing, to 160% of its cast size. Surface details are well-preserved.

Continuing our monthly materials themes for 2012, in October we’re featuring materials used in molding and casting. That’s a broad area, so in keeping with the spirit of the spooky season we’re focusing in mostly on non-metals—polymers and composites and stuff—of the type that are commonly used to cast costume parts and props. From plaster-of-Paris to platinum-catalyzed silicone rubber, if it can be poured into or around a mold, and then sets up to form a more-or-less solid part, it’s fair game!

As always, if you’ve got a hot link or a subject you’d especially like to see covered under this theme, don’t hesitate to let us know, below!

    Very nice, how much? I’ve seen the resin that shrinks, that stuff achieves amazing detail.

    I’m a woodturner, and I follow with great interest the casting wizards over at the International Association of Penturners (http://penturners.org/) in the Casting and Stabilization forum. They have cast everything from watch parts (http://www.penturners.org/photos/index.php?n=14692) to Snake Skins(http://www.penturners.org/photos/index.php?n=21462) into resin to be turned into pens.

    What about some cuttlebone casting… It’s easy to to also for beginners, and the results have that extra bit of organic appeal… http://cuntraria.wordpress.com/2011/11/28/cuttlefish-bone-casting/
