Vintage Royal Ruby Red Amberina Hobnail Fluted Bud Vase 6 inches

Why does ambrina red and yellow glass glow under UV light????: Amberina glass contains a precipitate of colloidal gold (as does gold ruby glass), which is heat sensitive and turns red at the right temperature. The main colouring agent that causes an orange glow under UV light is cadmium, usually in the form of cadmium sulphide. Depression glass: Please keep in mind vintage glass is good for having some scratches or little flea bite small issues in the glass. This is not uncommon due to age and rarely are items perfect. If they have larger cracks or issues I will show them in photos. Also many times in production items can end up with bubbles in the glass or even discoloration. Please use the pictures as your source to check the item out. Please feel free to reach out regarding any questions or concerns. I am a collector and seller of glass so you do not need to be concerned on safety in shipping! It will be top notch. I have safely shipped many glass items ranging from small items to large glass lamps without any issues. Items come wrapped in their glory with multiple layers of boxing to protect the items if needed!
