The Prince Rupert Glassworks is the factory owned by Lucinda Leplastrier. It represents the culmination of her mother's dream to own a factory, but ironically, Elizabeth Leplastrier's dream was of a factory run for and by women. She believed that industrialization would lead to female independence. Elizabeth was ahead of her time. When her daughter Lucinda purchases the glassworks, the men who work the glass make it clear that she is not welcome on the premises unless she's accompanied by Oscar.
