How to smelt ore manually ?

[netshaman]

I'm wondering to how smelt ores in a smelter MANUALLY.
I'm stuck on a planet without ANY other city beings after the home planet was destroyed by the asteroid , and crash landed with the rocket on it ( ! ) ; the perfect start for a stranded planet survival experience  ! ^^
So i' m ALONE with NO ONE to make working the infrastructures .
I ' m forced to do the work manually for every  building.
This isn't a big deal but there is one thing that bugs me out : i juste can't smelt ores that are in my backpack .
I tried to put them on the ground of the smelter , but this does nothing , i tried to sell them to the retail store or directly to the smelter , this does nothing too; they just stay in my backpack even if it is said " offer bid accepted ".
How to make them "workable" and smeltable , how to insert them in the "city items circuit" ?
As i want to quit this planet by constructing by myself my own spaceship ( this will take a LOT of time , but will be so satisfying as a survivor experience on a stranded planet  ! )
Thank you.

If you stand on a Smelter building's site, you will see new options appear in your handcraft menu.
See: hazeron.com/wiki/Handcraft

Alternatively, you can sell the ore to a connected building and then run the Smelter's manufacturing process like normal.
