Glass, porcelain, steel, and a seal cut from natural rubber. No silicone anywhere, which almost nothing else in this category can say. The design on the glass is ceramic ink fired into the surface at 700 degrees, so it is not a sticker and it will not peel. Three small things we can't confirm yet: the glaze on the little logo on the stopper (the maker's own blog describes a print that gets glazed and fired above 1,000 degrees, which points to ceramic, but nobody has said so outright), the gold and silver print editions, and what the shipping box is made of. We've asked soulbottles. A straight answer on the glaze moves this to Silver; a paper-only box would make it Gold.

Caveat
no synthetic part at all; still unverified: the glaze on the stopper's logo, the gold and silver print editions, the packaging (we've asked). Classic-color print editions only.
Unverified
Still unverified, and being researched with the maker: logo print and glaze on the porcelain cap; gold and silver print editions; labels, stickers or hang tags.
Made in
