The issue of the mirrors was finally solved by Soraya.
She referred to the mercury brought from the laboratory and painted a bright layer of coating behind the glass, out of fear of poisoning risk from inhaling mercury vapor.
Light reflected much better on painted mirrors than on mirrors stuck with silver scraps. Roland set aside a batch of crystal glasses to make little mirrors and delivered them to every witch to keep. The witches were pleased to see their faces so clearly. Even the imperturbable Scroll smiled. Roland thought that the witches were still feminine in nature, even though they could not get pregnant.
