Hey all,
I'm looking for a decent melting point apparatus for an industrial lab, preferable using fairly small quantities, and either a digital or a decent manual dial temperature controller. Any recommendations?
Edit: Cost really isn't a big issue, but preferably less than $2-3k, and electric heating is a requirement.
This might be really dumb, I understand everything has it's own melting and boiling points, like water boils at 100 degrees celcius. But water can be hotter than 100 degrees, it'll just boil off faster.
What I don't understand is how they have lower melting point waxes when it's melted by the same wick as a normal candle. Its melting point is lower but can't it still get hotter? There's also the jet fuel can't melt steel beams argument (not a conspiracy theoriest, just genuinely confused) so would more fuel make it hotter? Is there a limit to the heat something can produce? One match is hot but a house on fire is much hotter.
Edit - I can't believe I got something we did in science classes at 12 years old wrong. As pointed out below (thanks all!) water does not go higher than 100 degrees Celsius. I think that's where most of my confusion was coming from. Thank you guys for your help!

Why is tin Sn melting point so low compared to steel melting point? (Mostly iron and nickel)
The metallic bond in steel must be stronger but why? Tin has 4 valence elctrons so shouldn't it be hard to break the bonds?
a JW question asked which of the following has the highest melting point: LiF, LiCl, LiBr, and LiI and the answer was LiF. does this mean that the smaller the atomic radius, the higher the melting point? why is this the case and does this hold true for boiling point too?
It stands for
Terrible Underwater Breathing Apparatus.
What is the current state of this? I saw some videos and they leave me with more questions. For example: Why would I use powder instead of a wire? Some people create metallic class by having a very large printing speed. I also saw in TV that mold casting uses inductive heating. So I would guess a very efficient way to heat a wire would be focus a microwave radiation on it. Thin wire and skin depth should match. Why do people use laser ( skin too thin, already blocked by plasma ) or 1 kHz frequency ( you cannot focus this ).
Also recently people build a house out of concrete. And all thick walls are made this way:
- build the skin (+ steel )
- fill the bulk
I feel like a bulk fill should create a higher quality material. With composite you could flow long fibers through it. I wonder if I could fill hot metal into cold metal and with precision temperatures around the melting point, things would be stable. Like "on the rocks" -- phase coexistance.
When you heat most things it becomes liquid. When you heat cake batter it becomes a solid. Does cake have a point where it will melt, or will it just burn? And why?
Why does tin have a low melting point but a very high boiling point when zinc has a higher melting point than tin but a much lower boiling point?
Shouldn't the inter-atomic forces that make a higher melting point also make a higher boiling point?
