The moretti intense black is much more expensive as you have already found but it does things that no other black can do. It can last a long time because you will only use it for a few specific things. The vetro black is good for opaque areas on beads....better than moretti which often ends up looking like dark purple unless you are making a solid bead of it. But, for the lace effect, I believe that only intense black will work. When it is heated a lot, it spreads out with lines radiating out of the edges. Lines made with intense black do not stay crisp when heated fairly hot. It will do this whether it is pulled thin or applied in fat lines. This can sometimes ruin a design....so it is not always a good thing. It can also add a wonderful organic aspect to the bead that just can't be beat. I recommend that you buy a quarter pound and try it out. Refer to the info on Jim's website and then play with it; it is fun! But don't use it for your regular black glass.
