I have no connection with the following company but thought it might  help you with any chipped or broken pieces.

Recently in France at an antiques market I saw several lovely Lalique figurines that I passed by as I thought they were too badly chipped... so I left them there (and no I won't tell you where it was   I'm going back soon ..<grin !>

I was browsing the web today and came across this company:
http://www.brueningglass.com

One of the services they offer is to repair chipped lalique and other glass.
They also do repairs to:
Barometers
Broken Decanters
Chandeliers
Chipped Glass
Chipped Stemware
Lalique and other fine Glass
Glass Glueing
Panel Lamp Repairs.

They have some very impressive before and after repair photos on their website and its worth bookmarking this page to fix anything you may get broken (by next doors cat of course !)

They sound interesting - if you have had any glass repairs done by this company then a review here would be nice... if you have a moment.
