While PTFE is stable and nontoxic at lower temperatures, it begins to deteriorate after the temperature of cookware reaches about 260 °C (500 °F), and decomposes above 350 °C (662 °F).[26] These degradation by-products can be lethal to birds, and can cause flu-like symptoms in humans.[26] In May, 2003, the environmental research and advocacy organization Environmental Working Group filed a 14-page brief with the U.S. Consumer Product Safety Commission petitioning for a rule requiring that cookware and heated appliances bearing non-stick coatings carry a label warning of hazards to people and to birds.[27]
Meat is usually fried between 204 and 232 °C (399 and 450 °F), and most oils will start to smoke before a temperature of 260 °C (500 °F) is reached, but there are at least two cooking oils (refined safflower oil and avocado oil) that have a higher smoke point than 260 °C (500 °F). Empty cookware can also exceed this temperature upon heating.
众人担心不粘锅,是因为听说TEFLON会致癌
TEFLON是DuPont公司所产的不粘涂料PTEF的牌子, 也代表它的生产方式.
PTEF本身不致癌,致癌的是传统生产过程中所需要的PFOA(全氟辛酸).
这是用来催化乳化效应.
现在有厂家已经开发出不需PFOA的生产PTEF的过程.
DuPont 还没有能做到,但保证将来会(2015年之后)
新一代的不粘锅许多牌子用了不用PFOA的PTEF ("PFOA free"), 包括下面的系列:
--Scanpan Green Tek
--Swiss Diamond HD
--Earth Pan
--Cuisinart GreenGourmet
以后用锅的时候还是小心点为好

铁锅想不粘很容易，先把油热一下，不用太热，7、80度就行，再端着离开火一小会儿，转一转油，再放到火上，煎蛋、煎鱼，或者炒什么，都不粘。
I bought a Greenpan set from Costco last month. So far so good. Healthy ceramic non-stick, of course, I only use middle fire most of the time.
老婆用得很小心的，还是不行。
新一代的Thermolon Rocks不知是否好些。

配饮料味道绝对好。我也喜欢威士忌，却不欢喜白兰地，因为太甜。红酒越干越有味道。中国的茅台，五粮液，如果不是假的就的醇香无法抗拒。然而我不嗜酒，只是品味。我发现没有任何可以替代。我既喝茶也爱咖啡。新鲜茶叶的魅力无穷，咖啡牌子之间相差甚远。不同意说喜欢红酒的人是在装，用自己的无知评价他人的爱好，其实只是自己不懂红酒的魅力而已。为什么不学学，发现其中之奥妙。千年的历史驰骋世界一定有他的道理。不怕得罪谁，只是说出实话。
