      Yep, my parents still have one. Although you better not touch it. Or lean anything on it. Or have something to flammable nearby. Or…

      Not to mention the fact that steel fireplaces are being manufactured for use in homes, so someone figured out how to keep it from causing issues.

          In EU asbestos is illegal, and we have lots of cast iron and plate iron fireplaces for burning wood.
          For optimal and cleaner burning they have very light ceramic plates, no health problems whatsoever.
          I’m no expert, but I think it’s the same base material used on the space shuttle, which AFAIK is also used on spacex starship.
          Some sort of silica, that is pretty cheap to make.
          So no I don’t think any fireplace would be made with asbestos today, if that is the case that they do, I bet it’s only in USA.

      It’s oil from your skin. The pretty heat colors on the stainless steel are a result of oxidization of the metal, which reaches different depths as it gets hotter - but if the metal is heated rapidly enough, or to a low enough temperature the steel will begin to discolour before the oils burn off. Since the area with skin oil on it has a barrier between the metal and the oxygen (the oil), the outline of the hand is prevented from gaining a color and thus it shows up like this.

          It’s neat to see in person, with a light touch you can easily see the distinct patterns of a person’s fingerprints outlined in some really pretty colors.

      You got a solid explanation but I’ll add this; No one could press their hand on that hot engine long enough to make a perfect print like that. Somebody did it for giggles.

      If it’s properly insulated, might be fine. I’ve had a metal hearth with a lot of insulation under it and there weren’t any issues. But if it’s a wooden house and there’s not enough insulation, it might set shit on fire.

      If it’s conducting a lot of heat and a kid sits on it they could get hurt. But I think most of a fireplace’s heat travels upward in the rising gases. IANASOE

        Wood stoves have something called a baffle plate that redirects hot air so that it flows along the interior top of the unit before leaving through the chimney. The purpose is to heat the metal enough for radiation tranferrance. I often put a ceramic-coated cast iron kettle on top, and it will boil if left for a while. Anyone who sits on the stove would have a very bad time.

        Built in fireplaces work differently but aren’t typically sit-onable.

        Lots of people have steel hearths and not many of those people fry an egg on them.

        If you’re getting it hot enough to do that you have issues and you’d probably crack the concrete or stone at the point.
