Glass sheets are shown in the Makeshift forge, and yet the forge is unable to get up to the required temperature to convert the glass shards into glass sheets.
If the temperature requirements are not a bug; why is glass listed and showing as able in the makeshift forge?

Glass shards need to be heated to 1760°c to make glass sheets, your forge temperature in your screenshot is only 1650°c. You need hotter burning fuel. Not a bug
