First and foremost allow me to say that 2D is my medium of choice...and I'm green to sculpting as a whole- second and....least-most...? I Love props and have always wanted to make them from scratch rather than continue with the typical kits I usually purchase. So I recently decided to try my hand at a sculpt of one of my character's helms in the hopes of casting it in resin and getting some practice at mold making as a whole...however; my supplies were mediocre at best.
I had a ton of sculpey and no cash to get NSP in bulk (which I would have preferred) so I used what I had....here is the very rough result…
Lumpy lopsided potential, no?
Well I thought it was lovely anyhow.
I built up the neck a little more to give it support and it lasted about three days before it cracked and the cheeks and back fell off in a neat clump. I assumed it was dry and needed to rejuvenation so I added some softener....then the next morning it happened again...and again all week- being whole in the morning and a mess by the time I got home from work (8 hours)
Frustrated I assumed the weight was simply too much and put in some small wood supports…yet today, once again pieces fell…I added more but I’m certain it’ll happen again.
So! Here I am, asking for your advice RPF, I have long envied and adored your talents and can think of no better mentor (s) to teach this eager student! ….Please.
Now I realize sculpey isn’t typically the choice clay for this but I have been reading up in these forums and other sites that Casting is doable when unbaked…hence comes my molding questions I have a small brush on starter kit from smooth-on I was planning on incorporating into this project….it provides me with the following:
-sonite wax (wat?)
-rebound 25 silicone rubber (brush on platinum silicone rubber- 2 lbs)
-thi-vex II silicone thickener
-Plasti-paste (support shell?)
-and one small thing of 300 casting resin.
Now…I doubt this is enough to finish a project of such size so I know I need more resin but just how much more of the silicone rubber do I need? Is 25 the right kind? And the support shell…where do I buy that stuff separately? Ugh I have so many questions…if you read this far thank you. It means a lot.
