Best outdoor-safe casting material for garden bird baths

[moldymischiefmaker412]

I could use some advice. I usually work with epoxy resin for indoor stuff, but my aunt has asked me to whip up a couple of decorative bird baths for her garden

I'm on the lookout for something that can withstand the weather and is safe for wildlife, considering that birds will be drinking from it. I've heard good things about Jesmonite AC730 for outdoor use, but I haven't tried it myself yet. I also have some Smooth-On Onyx Fast resin sitting in the shop, but I'm not sure if it'll hold up against the elements

Has anyone here made outdoor pieces like that? I'd love to hear about what materials have worked well for you

Based on my experience, I believe Jesmonite AC730 would be a great pick for that. I mean I think... considering the weather resistance and low toxicity. If you want another option, concrete with a sealer works too. It's simple and sturdy.
