Loetz Wellenoptisch was a mold pattern used in different decors. (1) shows it in spreading green over clear, 6". (2) uses Candia Silberiris, 9". The next two pictures show Wellenoptisch in a decor called Oceanik: Olympia ground (which means these vases glow under UV light), with light bluegreen spots.
Note: after I had written the above, I tried the UV on the Spreading green vase, and it did glow! So, the ground must also be Olympia. My guess: an Oceanik variant.
