Built for this small “grape vine” base out of Spectrum Blackberry Cream Opal Art glass. It’s amazing that the colors are so strong on the surface but it’s really chameleon glass. Put a bulb in the lamp and it almost whites out. Put a colored bulb in it and you get an entirely new color! A red bulb turns it orange……can’t wait to see what a blue bulb does to it! Will it turn the lamp the pretty blue I planned on?
