I want to know the answer to the following question:
What color of ceramic glaze was extracted from uranium oxide?
All the background I'm provided with is that "Starting in the late Middle Ages, pitchblende was extracted from the Habsburg silver mines in Joachimsthal, Bohemia (now Jáchymov in the Czech Republic), and was used as a coloring agent in the local glassmaking industry.". Is that enough to answer the question?
Answer: no
