Made without metals, Always 100% Non-Toxic

Unlike metal or non-stick cookware, pure ceramic does not leach heavy metals or unwanted toxicants into your food. With us, you’ll never find Teflon, PFOA, PFAS, non-stick coatings, or a metal core.

HANDCRAFTED BY SKILLED ARTISANS

Throughout history, high-quality ceramics have been passed down as family heirlooms connecting present generations with the past through love for cooking. Our pieces are handcrafted by specialty Chinese ceramic artists – the only culture that has produced ceramics for millenniums, making it the perfect place to produce our unique cookware.

THE PINNACLE OF VERSATILITY AND CONVENIENCE

Our signature ceramic can withstand extreme temperatures and conditions so throw it on the BBQ grill, over a fire, in the microwave or in the dishwasher for ultimate versatility and convenience.

FIT FOR A MUSEUM. OR YOUR DINNER TABLE SERVEWARE CENTERPIECE

Modern, glossy, strong and an excellent heat retainer, our ceramic cookware is made to be involved in every part of the meal from prepping to laughing around the breakfast, lunch and dinner table.

BY OUR FAMILY FOR YOUR HEALTH

A lot of companies are created to lower the bottom line and increase profits. At Xtrema, we don’t touch our bottom line – our products are our integrity. And as a family-created and still family-run company, that’s our promise to you – we’ll make decisions with your family and your health in mind as we would our own.

Food tastes better with Xtrema. Seriously.

We thought it was possible, but we had our customers review us just to
make sure. Turns out, it’s true. Pure ceramic not only helps food retain its
original nutrients at high levels so it’s healthier but pure ceramic has
properties that don’t temper down flavor profiles.

its consistent, non-toxic heating properties.

Find Out More About Non-Stick

In 15 years, our cookware is tested and proven to continue to be in good condition and of high quality - keeping millions of non-stick pans that would've been bought, and, forever chemicals out of landfills.

A lot of cookware contains PFAs - aka 'forever chemicals' that are so stable they don't biodegrade. They can cause damage to our livers, kidneys and even lead to cancer. Xtrema is certified PFA-free to keep forever chemicals out of your body and our shared planet's soil.

Great quality

I’m thoroughly impressed by the quality of this container. They are lightweight, yet sturdy. Very high quality, “clean” platinum silicone. I get the impression these will be durable for years to come.

Great for travel and leftovers!

These bags are super versatile, easy to clean and great for storing leftovers in the fridge for the week. The best part is that you can see what is in your bags and they STAND up, truly outstanding. We went on vacation and packed toiletries in the larger bags and used smaller bags to bring along spices and other kitchen staples for the week. Super useful, a new kitchen staple of ours for sure!

sturdy, stands up and stays open, easy to use and to clean

So i have bought silicone storage bags before and this is by far the easiest to use and the most sturdy. The flat, round base keeps it standing up and staying open while u pour things in. The seal pinches together and matches up very easily and it’s not flimsy like all the other reusable silicone bags that I have bought in the past. This is a great storage bag for anything, but I wouldn’t consider the seal as leakproof if you turned it upside down, so u can store liquids in it but u should keep it upright if you choose to do so. The corners don’t pinch closed as tight as the rest of the seal, probably bc the silicone is thicker and sturdier than most. This is the only reason I gave it four stars was because some people might expect this to work like a ziplock bag commercial, which I personally wouldn’t even trust this perfect of a seal even with a ziplock bag anyway. Otherwise, I can’t find anything else wrong with this silicone storage bag and I think any kitchen could use all sizes of these!
