a blogger had left me a question a while back that i thought i would answer in a new blog post. the question was, "what's the difference between Fire King's Turquoise and delphite?"
Fire King's blue glass is called Turquoise. it is a robin's egg blue color (see photo of bowls). they made this in one style, which is very plain.
Fire King also made a lighter blue-colored glass called Azurite. it is a very pale blue that almost looks white like milk glass. this glass came in 2 designs: charm (like the teacup below) and swirl.
other glass companies like McKee and Jeannette had a blue that was more of a medium purplish-blue. that is called delphite. milkglassvintage has a great example of a delphite reamer in their shop (below).
