Lol istandalone "the dimple of death"
I say "Fear not the dimple of death" easy to remedy that once you know how.
Try this: Do just a clear maria, no design, no nothing on it. Melt it so you get this dimple of death going. Forgive crude drawings, this is susposed to
represent that indentation, not a dog bone.
Now change the angle of your maria holding the rod that the maria is on at angle so that the flame and gravity pulls glass out to the side of the maria
,then finish with flame on the center again to tighten it all up.
Once you master this, you will never, ever get that dimple of death again, and you will be able to add more layers and get things to tighten up better
with more control.
