When melting items most of metal just disapear. Following mc2=E there should (doing melting) be nuclear blast.   Its very inefficient recycling!!! I was so disappointed about this that stopped playing DF. 1 ton of steel swords = 1 ton of steel bars! Not 1 ton of steel swords = 0.3? ton of steel bars.

They don't disappear. They become 1 3rd of whatever the object was made of. i.e. something that took one bar to make, and you melted three you'd get one bar after melting the third.

[andris-berzins]

and where 2/3 of material?
I have 100 bars of steel. I make swords and melt them and so on ... and end up without steel. ?

[wallish]

You stop playing because of a lapse in general relativity yet the perpetual motion machines or even the MYTHICAL creatures and UNDEAD/SKELETAL monsters fail to phase you?

[Align]

The other thirds are lost in the process due to spilling and the re-smelting polluting some of the metal or whatever.

There was no dwarf named Einstein.  If you don't know about something, it doesn't apply to you, hence, why babies can fly.

[andris-berzins]

loss of 2/3 does not make sense! loss of 1/20 maybe

Recycling one ton of steel saves 1,100 kilograms of iron ore, 630 kilograms of coal, and 55 kilograms of limestone.

Iron and steel are the world's most recycled materials, and among the easiest materials to reprocess, as they can be separated magnetically from the waste stream. Recycling is via a steelworks: scrap is either remelted in an Electric Arc Furnace (90-100% scrap), or used as part of the charge in a Basic Oxygen Furnace (around 25% scrap).[15] Any grade of steel can be recycled to top quality new metal, with no 'downgrading' from prime to lower quality materials as steel is recycled repeatedly. 42% of crude steel produced is recycled material.

Gee man, you're playing a video game full of dwarves and elves and dragons and such.  There's pits of magic metal under the mountains full of !!hidden fun stuff!! and bronze colossi wandering the plains.  Ratmen and batmen hang out and play cards on weekends.  Lava is a magical chunky fluid that produces neither toxic fumes nor insanely intense radiant heat.  And these are only a few of the fantasy elements of the game.
And you stopped playing a FANTASY game because it violates that particular physical law?
No offense man, but that seems like a kinda minor point to be sore about.

[Cthulhu]

That's like quitting Morrowind because there's no horses.  It's madness!

And none of these specialized furnaces are available in DF.

While andris-berzins arguments may have been a bit anachronistic or thematically inappropriate, I do agree with his sentiment that melting objects should have a higher return ratio.

If, following the suggestions of many other posters on this forum, alloy quality levels are implemented, one could have the quality of the metal reduced one level instead of having it disappear into nothingness.

[Align]

Higher ratios sure, but for realism reasons is silly.

I just scanned that, but seriously, how are primitive dwarves going to develop an electric arc furnace?!
