I finally got around to doing the mold of this whole panel today, it's used one gallon of silicone and while that's probably enough I'm going to pile on some more to be real sure as well as make it heavier thickness.
I used the QM140 but this time ordered the regular cat and the thixotropic cat along with 2 gallons of base.
With the regular cat I wanted to have it stay liquid so I could get it into all those DEEP egg-dart moulding crevases and details and fill them completely solid, then go over the whole thing with that, and then go over it with the thixotrophic. That way I can get the stuff into all those details with hopefully a minimum of airbubbles, unfortunately this sculpture has a LOT of texture, incised lines, deep undercuts- 1/2" or more, so this is going to be a pain in the behind and I know there's going to be air bubbles.
Have one more application to put on now and since it's late, Sunday I won't get to the plaster shell till next Saturday which is fine since the silicone increases in strength over 2-3 days and with all the deep undercuts the extra strength would be good.
Not sure if I'll get to do anything on the owl panel tonight but I did find some good owl photos that should help.
