The lovely cranberry base colour of these Nassau Cups is made with gold. When added to molten glass gold tints the material various shades of pink hued red.These cups are for someone who wants to add a panoply of playful thoughts to their rose-tinted glasses. The tumblers vary widely with decoration that can range the full spectrum of earth tones, jewel tones, primary colour blocks, sparkly bits, dots, lines and squiggles. Made by rolling random handfuls of colourful bits onto molten glass, that is fused and formed into a cup. Each cup will be entirely unique from the ones pictured and we can't guarantee that certain colours will or won't be present. It'll just be a pleasant surprise.
