casting fishhooks
Posted: Sat Jan 10, 2015 3:15 pm
I might try casting a small slab of glass with stainless steel fishhooks in it, to use as a piece for a piece of sculpture. Might by 6" x 6" x 2"or 3" thick. I did a quick run with a
fishhook between a couple of layers of glass at a pretty high rate of speed, maybe 300 degrees to 1150, hold 30.......150 degrees to 1250, hold 40....300 to 1429, hold 50. The
glass didn't crack but of course I had a big air bubble in the curved part of the hook.
I would take it up much much slower in a slab, plus do a much much slower cool down and anneal. If the air bubbles are unavoidable because of the thickness of the hook itself, would they be a problem as far as possibly making the slab crack at some point? I may not mind the bubbles. Anyone ever cast hooks before? If they don't work I may go with razor blades....Thanks! Kate
