This question comes from Connie:
I’ve been reading the blogs thru your site but haven’t been able to find exactly what I’m looking for. I have several teeny bird and mouse skulls that I want to make molds of and cast in an opaque creamish (bone) colored resin. I read where it’s important to pre spray with Gloss Sealer on the skull – makes sense – But there are so many choices for mold making materials I’m lost. Also, I didn’t see a resin that was the bone color I’m looking for.
Can (will) you help? As always, I’m hoping to get going on this project quickly – my next art show is in 8 days.
thanks for all the hard work you’ve put in to this site. -
Hi Connie,
Thank you for the kind words. 🙂
For your project, you are going to need to make a two part mold. If you cast your skulls as one part, you won’t be able to demold them after the resin has finished curing. The team at Composimold did this video for us on how to mold and cast a dinosaur. The same concept would apply to your project: https://www.youtube.com/watch?v=DejiH6M9qBM&t=2s
As for a mold making material, if you are new to casting, I would definitely recommend using the Composimold material. You can remelt and reuse your mistakes. If you are experienced with mold making, then you can jump directly to using one of the silicone products. All of them can be found here: https://shop.resinobsession.com/collections/mold-making-materials Putty would not be a good choice here because you won’t get the two parts to come together without leaving gaps for the resin to leak.
As for the resin choice, I think the Alumilite Amazing casting resin would be a perfect choice. https://shop.resinobsession.com/collections/resin/products/alumilite-amazing-casting-resin-16-oz-opaque-white There is an example on that page of when I used it to make Halloween charms. I think it would match your ‘bone’ color fairly closely.
