Tips for When Alginate Goes Wrong is a simple study in 'snaps,' the alginate brush-up for prosthetic molding that will be cozied into a rigid shell and then backed with yet another hard material...usually a stone or other pourable hardening substance. Everyone who's ever tried it knows there are a few things to look out for.

But when Rob gets to man-handling this seaweed derivative, it's like putty in his hands. And once you've watched him, it won't be long before you drop any concern you ever had about it and jump right into your first perfect snap mold.
