Silicone has a reputation for being "the safe, bendy stuff" — and most of the time, that's earned. But "silicone" is a category, not a spec. The way raw silicone gets turned into a finished, solid part radically changes how pure, durable, and clean it ends up being.

That transformation is called curing (or crosslinking): taking gooey raw polymer and locking its chains together into a stable solid. To kick that reaction off, manufacturers add a catalyst. Pick the cheap catalyst and you get one kind of material. Pick the precious-metal one and you get another. Every Eyce piece is built with the second kind — platinum-cured silicone — and below is exactly why we refuse to cut that corner.

How curing actually works /

There are two crosslinking systems that dominate the silicone world, and they get to the same finish line by very different chemistry.

Platinum cure is an addition reaction. A platinum catalyst tells a hydride-functional silicone and a vinyl-functional silicone to grab onto each other, forming a clean bridge between the two chains. The magic detail: the reaction produces no byproducts. Everything that goes in becomes part of the final material. Nothing needs to leave.

Peroxide cure is a free-radical reaction. Organic peroxides are heated until they break apart into reactive radicals, which force the silicone chains to link up. It works — it's been used since the early 1900s and it's cheap — but the process leaves behind volatile leftover byproducts (typically volatile organic acids) that have to be baked out afterward in a post-cure.

No byproducts means nothing left over to off-gas, bloom, or migrate into your hit. That single difference cascades into everything else.

Meet "blooming" /

Here's the most visible downside of peroxide curing. When leftover catalyst slowly rises to the surface of a finished part, it can form a powdery white film — manufacturers literally call this "blooming." That bloom is largely those volatile organic acids, and it's why some cheaper silicone feels faintly oily or greasy and can carry a slight odor.

Peroxide-cured parts get a controlled, ventilated post-cure bake to burn most of it off. "Most" is the operative word: because trace catalyst residue can't be fully guaranteed gone, peroxide-cured silicone is generally steered toward industrial and construction uses — gaskets, seals, weather stripping — where durability matters more than purity. It is not the standard for food-contact or medical applications.

Purity, strength & staying power /

Because platinum curing is so clean, it tends to win on the metrics that matter for something you put to your lips and your lighter:

Platinum-cured silicone generally delivers better tensile strength and elongation — meaning it stretches further and resists tearing better — and it holds its flexibility across a wide temperature range instead of stiffening over months of heat exposure. It's also a higher-purity material with little to no byproducts, which is why it's the default for medical devices, baby products, food and beverage gear, and high-end smokeware. Properly formulated and tested, platinum-cured silicone meets the strict purity bars (think FDA food-contact and USP Class VI medical standards) that peroxide-cured silicone typically can't claim.

To be fair to chemistry: peroxide curing isn't "bad." It's often cheaper, cures at lower temperatures, and can actually offer better compression set for long-term industrial seals. It's simply the wrong tool for a product designed to handle heat, repeated use, and your airflow.

Platinum Addition cure ■ Zero curing byproducts ■ High purity — food & medical grade ■ Superior tensile strength & elongation ■ Stays flexible through heat cycles ■ Clean, non-oily surface — no blooming ■ Costs more, demands a spotless process

Peroxide Free-radical cure ■ Leaves volatile organic acid byproducts ■ Needs a post-cure bake to burn off bloom ■ Can feel oily; may carry slight odor ■ Trace catalyst residue can't be guaranteed gone ■ Best for industrial seals & gaskets ■ Cheaper, lower cure temperature

Spec that matters	Platinum	Peroxide
Curing byproducts	None	Volatile acids
Food / medical grade	Yes*	Generally no
Surface feel	Clean & dry	Can be oily
Flexibility under heat	Holds up	Can stiffen
Typical home	Smokeware, medical, food	Gaskets, construction

*When properly formulated and independently tested. Curing chemistry sets the ceiling for purity; certification confirms it. Platinum curing is what makes food- and medical-grade silicone achievable in the first place.

Every piece, platinum /

Easy answer: platinum, always. Every Eyce silicone body is built from platinum-cured, food-grade silicone — then paired with the parts that should never be made of silicone in the first place. Borosilicate glass downstems and bowls, quartz bangers, and titanium hardware handle the direct heat and the flavor, while the platinum-cured shell takes the drops, the heat, and the abuse.

We don't pick the catalyst that's cheapest to buy. We pick the one that's cleanest to breathe through.

That choice costs more and demands a far more careful, contamination-sensitive process — platinum systems will refuse to cure properly if they're contaminated. We think a piece you put to your mouth and torch on the regular is exactly the place not to save a few cents on chemistry. It's the same reason every Eyce piece is backed for life.
