When dropping alcohol inks, they look dirty. How can I apply better?

when applying different color inks on clear glass vase they combined into a muddy black spot on the vase. I had to use blending solution to rub it out. I lost the various colors and ended up as the burgundy glass. And it ended up with vertical lines. I had Wanted to make different shades of reds.
The blue glass ended up as one shade of blue. I used the felt applicator n muted the colors. But again, ended up as one color. Since the AI wasn’t pretty alone, I applied silver glitter glue. Another question: as i have the silver glitter glue on the yellow, could I go over it all again with the yellows and try to make it more intense ? Wouldn’t hurt at this point? Thanks
