Space Exploration allows melting ores using pyroflux to create molten iron/copper to convert into ingots as a semifinal stage in smelting (with K2 installed, molten metals are made with K2's enriched ores and pyroflux, instead). Each ingot can be converted into 10 plates, making them far more efficient to transport.

Would it be possible to add recipes for Space Exploration that consume Iron/Copper dust + pyroflux and produce Molten Iron/Copper?

Pretty complex it seems.
I'll see what i can do, SE is really a complex mod, especially if put together with K2 or some other mods.

If it would be easier, changing the existing molten metal recipes from Raw Ore / K2 Enriched Ore to use the respective dust instead would also work.

Will give a watch then.

Nop I need a proper tutorial for this one. xD
Will give a watch to Nilhaus or smo else in the future.
This also to see what Earendel plans to do with Space Age and Space Exploration.
