is a very conservative estimate for the the heat resistance of GIR's silicone. In fact, all of our tools will perform admirably at temperatures higher than that - the food-safe silicone we use is not readily combustible, and does not melt or drip. It may discolor around 550-570°F290-300°C or so, with prolonged exposure.

Why not higher?

Aren't there silicone spatulas with temperatures like 600°F 315°C or 700°F370°C listed on the packaging?

Many manufacturers' claims about this aspect of their materials are misleading. There's no special "secret formula" silicone that is food safe but more heat-safe than the rest of the pack. In fact, silicone cooking tools that cite resistance to temperatures like 600°F315°C of 700°F370°C are basing that claim on conditions that really can't occur outside a lab. Great for marketing, but not so good if you actually want consumers to know the product's true performance limits... say, in a searing hot wok or pan.

Here's the deal:

Food-grade silicone products that claim higher
heat resistance are simply citing results of
lab tests like thermogravimetric analysis
(TGA) conducted in inert nitrogen or
argon gas. The presence of oxygen
(like, in every kitchen on planet earth)
will typically cause partial oxidation
above 572°F 300°C so that's about where
degradation (or technically, "weight loss" as
a result of depolymerization) will start to
occur at a rapid rate.

To sum it all up,



We're confident in saying 464°F240°C for prolonged heavy-duty exposure, and we know that science is on our side. Truth is, you could take it much higher if you're willing to test the limits, with some risk of discoloration if you're too bold and it hangs around +550°F +290°C for too long.

Heat Retention

We use a fiberglass core to give our tools strength and heft, which has the added benefit of low heat retention (unlike metal). We're not saying that they can't ever get hot - stick 'em in a pot of boiling sauce for a few minutes and yes, the contact areas will heat up. But they won't retain that heat for long, and won't transmit it along the handle.

So if you're using them in a hot skillet and want to turn around for a minute or two, you can do so with little worry. We simply want to qualify the claim of heat resistance with a request that everyone exercises a bit of common sense when testing the limits.
