Completing the quest in Kolselmo's Lab !! (The Elder Scrolls 5: Skyrim)

Find coal and a roll of paper there

Risman
where exactly in the laboratory itself or in the museum ?????

Look for the hall where the plaque is located. And it doesn't matter where you find them, if they are lying around in the inventory, they will also go.

Coal and paper, NNZ, can be bought from merchants and blacksmiths. But even in the laboratory itself there is plenty of waste paper and coals.

Thank you very much !!!!!!!!!!!!!!!! already passed !!!!!!!!!!!!!!!!!!!!!!
