Of course there’s no difference. Glass is one of the most recyclable materials there is.
As long as it hasn’t been coloured I believe.
This might seem like a dumb question but couldn’t you burn the color out during the recycling process?
“Burning it out” still leaves contamination. You need to remove it.
It’s metal ions. You can compensate for iron with manganese, but you’ll still get a grayish glass with reduced transmission.
This makes sense. Thank you
