I need some help. If anyone can tell me.
There is an art show coming up and I've been making some icicles for the first time. I am using boro but have never worked with boro before. As the little container of the ones I have made tipped over, I lost 4 of the loops at the top. So.. most likely they weren't annealed properly (????)
are they something I can reintroduce to the flame and add loops?
and what do you use as an annealing cycle for boro?

any icicle tips? I'm focusing on glass for this show and hope to have a display of pretty icicles but don't want to waste my time if they are so easily breakable.

thanks!! SusanLambert

Even with annealing, if your glass is thin it will break if dropped or bumped, etc.

Thanks Robin
It didn't drop far. Like it tipped over in a box and a bunch of them jostled. I would expect something like a wine glass to break in that tip though, so maybe the issue was just the hooks are thin.
I appreciate your thoughts!

A good cycle for boro is as follows:

1075 hold for 1hr
down to 960 over the next 2 hrs
elements off.

If the welds at the loops are not fully melted in it could still pop off.

Instead of loops try using 'peter tweezers' to put holes in the tops. Less likely to break. And yes the boro has a very good chance of surviving a reintroduction to the flame.
