After etching for 20 min then being washed, and soaked with baking soda most of the beads are streaky. its weird. It is the same problem I had the first time I etched some teal. hummm.... This leads me to believe that maybe I should be washing my beads in vinegar or dish soap first, and maybe there is an invisible slime residue????? I will re-etch the beads after I take another photo of them. I will etch for another 20 min. I think there are a few that came out OK. Maybe the lighter browns, and pinks. If they were etched well @ 20 min I will remove them and just etch the others.
Here is the first picture (20 min etching time-baking soda water bath and a good rinse)
