    note that ‘ceramic’ water bottles (lining - frank green) - and “ceramic” sauce-pans and cook-ware are not made of clay - they’re made of a bunch of chemicals, teflon has some health concerns, but a bunch of research has gone into it, not so much into ‘ceramic’ products clay ceramic is not naturally non-stick , hence the other chemicals used

    bunch of notes on ceramic:

    How ceramic coated cookware is made

    A ceramic coated pan is essentially any metal pan that has a thin ceramic layer on top. The metal core or “substrate” of the pan varies. Some companies use anodized aluminum, an inexpensive metal and good conductor of heat; other brands use cast iron or stainless steel. Whatever the case, all ceramic coated cookware use some type of metal as a base.

    Most ceramic coatings are actually “Sol-gel” coatings consisting of silica (sand) and other inorganic chemicals. This is the preferred method of applying ceramic coatings to cookware to make them less- or non-stick. Sol-gel is typically sprayed onto the metal substrate and then fired at a very high temperature. Depending on the manufacturer, this curing process can range between 400 and 800 degrees fahrenheit. While Sol-gel coatings are technically harder and able to withstand higher temperatures than PTFE coatings, most companies advise their customers not to heat ceramic coated pans above 500 degrees, otherwise the ceramic coating could decompose. When this happens, the ceramic pan can lose its nonstick properties and the surface will become coarse or gritty. These pans are not usually recommended to use in the dishwasher or under the broiler.

    Are ceramic coatings nonstick?

    Ceramic is not naturally nonstick. This is why most companies use Sol-gel technology to create a ceramic nonstick coating. But the idea of ceramic nonstick cookware is kind of a misnomer. First, as we learned above, the slick surface on ceramic coated pans usually degrades over time; and this process can be accelerated if the pans are exposed to high heat on a regular basis. Some experts have suggested that ceramic coatings have about one sixth of the lifespan as their PTFE counterparts. The question you should really be asking is, for how long are ceramic coatings nonstick? A well maintained ceramic coated pan is expected to hold up for 1-2 years - that is not very long, especially considering the high price of some of these pans.

    Is ceramic nonstick cookware safer than other nonstick cookware?

    Because of all the controversy and speculation surrounding fluoropolymers and PTFE coatings, it is no surprise that there’s an abundance of scientific research on these chemicals. Unfortunately there is not a lot of historical research on Sol-gel and its effects on human health. That is not to say that one is safer than the other. However, purchasing your cookware from a reputable company can help limit your risk of direct food contamination. As the old saying goes, it’s better to be safe than sorry.

    Actually Moses was VERY prudent, and strategically didn’t use the exact word ‘apple’ only ‘fruit’ and ‘of the tree’ - because he knew apple would be a litigious bitch

    Now the serpent was more subtil than any beast of the field which the Lord God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of every tree of the garden?

    And the woman said unto the serpent, We may eat of the fruit of the trees of the garden:

    But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die.

    And the serpent said unto the woman, Ye shall not surely die:

    For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.

    I like it ~ I joined mastodon but I think it was way too slow to load images - probably joined some dodgy overloaded server (though I like the Reddit format and community better rather than Twitter)

    It’s giving me Reddit 15 years ago vibes - smaller tech-savvy and agile community - my Reddit use was on and off through the years; but I like the idea that each community in the Extended Lemmiverse can all have their own vibes and cultures and implementations of the platform and we can all chat and follow topics together 🕊️

    I’ve only been here a short while; but maybe one thing I’d love is not to see reposts in the /all section ; I know the communities are small and growing and can cross post for more stuff , but I’m sure there could be a way for the system to know that the title and url are the same - so only show one , or auto-merge the comments and prioritise posting your comment to your local community instance’s post Edit - I might try install an instance on my website and try to make a merge function ~
