Default Murinni

If I bought murinni by the inch could I use my little electric tube saw to cut it? It's the little one from Harbor Freight used to cut tubing.

I don't think it will cut it unless you have a diamond blade. But not totally sure on that.

What diameter is it Deb? Is it a whopper?

Don't know if you saw this vid yet...kind of an interesting way to do the plunge and snap with murrini in boro...but probably only best for stuff up to about 8-10mm at the largest:

You could probably cut it, but you would end up with a lot of waste and potential chipping. On top of that, all saws leave a rough cut that needs to be polished or it will scum up when put into the flame.
Normally when one cuts with a saw you have an extremely thin lapidary blade and then spend a few hours polishing each slice, which is why it is only done for very large pieces.

If you are extremely careful I've heard you can flame polish the cuts but I've never had any luck (they just flop around and scum anyways). You can also tumble polish the slices if you have enough of them (at least several feet).

So the short answer is don't bother, nippers can be frustrating but they are really the only option. The plunge and snap thing works nicely as well, perhaps even better than using slices.

It depends on the size of them. I cut mine with my disc cutters. I had a set of end cutters, but I lost them. They worked really well.

I've also taken the entire murrini and attached it to a clear rod. Then I heat the spot I want to apply it, stick the murrini to it, wiggle it back and forth, and it will break off leaving just enough behind to see it. Works like a charm. Kind of tricky with larger diameter pieces though.

These are small, about 2-6 mm. I don't have any yet but before I bought them I thought I'd ask. I do the spot heat with soft glass so I'll try it with the boro. Thanks!

I'll see if I can find the link for the little saw. I got it in the store so I'm not sure.
That was easy...http://www.harborfreight.com/cpi/cta...emnumber=42307

you can do what cosmo said and after you attach the milli cool the spot where you want it to snap with a pair of pliers,scissors or something metal and it will snap very easily.
I purchased a pair of disk nips from devardi that have a super thin blade that work very well. If you want some milli to practice with i may have some scrap ends left around here i could send ya.

Chris I'd love them! I also want to buy some more murrini from you. I've used most of the ones I got already. LOL I love them! Do you have any that look kind of 'coral reef' like? I'll PM you.

You could always check on clear rod. Easy to tell the surface finish. You could also use it to practice with your tile nippers.

I don't know about the saw, but I have fire polished saw cut murini before applying to a pendant. You just have to work fairly cool and carefully.
