I am casting 50 deer antlers in bronze; testing out Shellspen ceramic shell for the first time, because the investment is such a hassle... my wrists can't take the weight anymore... anyway, the forms are so linear and "vent like" themselves, that I am wondering if I need to add additional vents. Casting them solid. I am spruing 2 antlers together in sort of a circle, with the cup at the wide ends... all tips are connected to the body of the antlers with 3/8" sprues. Not having to add additional vents would help the strength of the piece... must I?? thanks! Catherine Catherine
