Hi Rafa-
Rings are my favorite!!! It does take some practice, but after you get the hang of it, you can get them right on every time!!
You need a large hole mandrel...I have tried three different sizes....you just have to figure out which size will fit your finger. And you can also add a double or triple coat of sludge onto the mandrel, if you want to inch the size of the hole up a little bit.
First you heat the glass...about a two or three inch section of it....just flash it through the flame for a minute or two, until you feel it heating up. You want to have enough of the glass warm enough that you can cover the entire diameter of the mandrel in one application. Am I making sense?
Then, once you have one coat, go around again, to get a sturdy enough band. Then I melt it down and marver, to smooth it out. If you need to go back and add glass, to make an even edge on the band.
I find that the sludge will sometimes start cracking at this point. So when I go to add the centerpeice/focal point of the ring, I put it on the opposite side from the sludge crack.
Add some more glass wherever you want the bulk of the ring to be. From this point on, you just add glass and shape it to make whatever shape you want.
REMEMBER to keep heating the band of the ring while you are working on the details. That was my hardest part, other than the initial application of glass.
I hope these instructions are clear....I have never really typed out detail instructions like this before.
Feel free to ask any more questoins!
Good luck!
I will post a few pics below so you can see some of the rings that I have done!
