Encasing Double Helix

[SueP]

What is the best clear for encasing double helix?  I spent ages today heating and cooling my one rod of Luna and had some lovely colours right through to purple I encased in Reichenbach crystal clear but both my beads cracked - I have some vetrofond clear would that be better?  I seem to be having a problem with the Reichenbach and am starting to think that I have not got the 104 COE

Elsewhere, people suggested Precision 104 Diamond Clear, but I haven't tried it!

the ONLY rod jed and julie use to test their glass is vetro clear - this is due tot he fact that jed used to work for mike, mike REALLY rates vetro clear and it is the most forgiving (if not quite the clearest clear) out there..

Thanx for the quick response I will try my vetrofond tomorrow and see what happens
