1. What is PTFE?
Almost all non-stick pans are made with PTFE. PTFE stands for PolyTetraFluoroEthylene. PTFE has a very low coefficient of friction, which means that almost nothing sticks to it, hot or cold.
Up to 260° C, PTFE remains relatively stable. Above 260° C, PTFE starts to decompose and is known to release a multitude of toxic chemicals. That means harmful fumes can potentially damage your respiratory system and your pan can no longer be used.
2. What is PFOA?
During the manufacturing of conventional PTFE based non-stick coating, PFOA - PerFluoro0ctanoic Acid - is used and can escape into the environment. PFOA is classified as 'a persistent pollutant of the environment'. Besides that PFOA is a chemical that the body has the greatest difficulties in expelling and is it classed as a "likely human carcinogen".
PFOA is also sometimes called C8 but in some cases it is replaced by C6, which belongs to the same chemical group.
3. What is Thermolon?
ThermolonTM is the patented non-stick coating that GreenPanTM uses on its products.
ThermolonTM is completely PTFE-free, contains absolutely no silicone oil and uses no PFOA during its manufacture. It is a non-stick mineral-based coating with superior release properties.
Mineral materials are natural substances that are safe to use. The ceramic mineral materials that are used in ThermolonTM are the same as used to make glass and pottery.
Less energy is used when ThermolonTM is applied on GreenPanTM products, which means 60% less CO2 emissions when compared with PTFE-coated pans.
4. What is Sol-Gel technology?
This is a technology in which materials are formed from small particles suspended in Solution that Gel together to form a matrix. ThermolonTM is based on Sol-Gel technology.
5. Up to how many degrees is Thermolon non-stick safe?
Our ThermolonTM non stick coating is heat resistant up to high temperatures. This means that GreenPan has a safety feature. If you accidentally overheat your pan, even up to 450C/850F no toxic fumes will be released and the coating itself will not blister or peel.
6. Is it true that the best frying and searing results are with a plain (without non-stick) frying pan?
Up till now this was correct, because the only non-stick fry pans available were made with PTFE, which is a type of plastic that acts as a heat blocker.
The ThermolonTM non-stick coating is a mineral coating, which is a better heat conductor that is great to sear and fry your food with a crisp and tasty result.
7. Is it possible to store food in GreenPan non-stick cookware?
Go ahead! It is no problem at all. The ThermolonTM non-stick surface will give no reaction of any kind with the food.
8. Is the GreenPanTM cookware dishwasher safe?
Although it is, we advise you to just wash it with a little soapy water and clean it with a soft dishcloth or sponge. If you wash it over and over again in a dishwasher, the non-stick properties of all ceramic-type non-stick coatings slowly start to fade.
9. Can I use metal utensils for cooking or frying in my non-stick pan?
No, we do not recommend the use of any metal utensils. Nylon and wooden utensils will help you to preserve your ThermolonTM non-stick surface.
10. Do I need to use oil or butter for cooking or frying in my non-stick pan?
Yes we recommend to use a little oil or butter. Some oils can go higher in temperature - e.g. coconut oil is ideal to use in GreenPanTM.
Because of the excellent heat conductivity of your pan and the ThermolonTM layer, food and oil can carbonize very rapidly. So always cook on low to medium heat and only use short high heat for searing or browning.
11. Can I use oil sprays?
Better not to use oil sprays. Small spray droplets heat up very rapidly and are more easily carbonized on the non-stick surface. This will affect the non-stick performance of the pan.
12. Can I put my pan in the oven?
Yes, you can put your pan in the oven without any worries when it has stainless steel handles. When your pan has stainless steel handles with a silicone insert they are oven-safe up to 250°C. When your pan has Bakelite (mostly black-colored) handles they are only oven-safe up to 180°C. Always check on the packaging to be sure.
13. Is GreenPan cookware suitable for induction?
All our stainless steel or multilayer ranges are suitable for induction. For the aluminum cookware there are several cookware ranges that we have that are suitable for induction. To know if your cookware is suitable for induction, you always need to check the packaging. More info is available on our product page.
14. Do I need to season my GreenPan?
We used to suggest that you season your pans, but experience has shown that this is not necessary. All you need to do is clean your pan before storing and use a little butter or oil before frying.
15. What do I need to use to clean the interior of my pan?
We recommend that you use a little warm soapy water and a soft dishcloth or sponge to clean your pan.
16. How can I prevent food from sticking?
Thermolon is a better conductor of heat than a traditional non-stick coating. We recommend that you cook on a lower heat setting than you would with your traditional pan. This will prevent the food from burning. After use, always clean the pan according to our Care & Use Instructions.
17. My interior surface is scratched; is this a problem?
Scratches, dents or pits in the Thermolon coating won't affect the safety nor the performance of the pan.
18. How safe is Thermolon technology? Are there any chemicals used?
Everything is composed of atoms and molecules. Technically even water or table salt are chemicals. Our bodies are a bag of chemicals. Nothing can be made without use of chemicals of some description. The question is, are there any harmful chemicals used. Then you will have to define what is harmful and the degree of risk involved.
19. Does the Thermolon non-stick has any aluminum in it?
There are no free atoms of the metal aluminum in Thermolon. Aluminum is one of the basic elements that is combined with others to form compounds called alumino-silicates (clays). Such materials have been used to make earthenware pots for centuries.
