Hello
I'm interested in your 20" solid Pyrex mirror blanks. They do seem a good price.
Please can you quote for USPS postage to the UK? If you know the weight of the mirror blank, and the likely weight of packaging (I suggest a rough 3/4" plywood box, with multi-layer polystyrene inner) their website at www.usps.com should help.
Also, I have looked at your cellular design blanks, and whilst they look attractive, you mention the possibility of bubbles near to the surface? Do the solid pyrex blanks exhibit the same bubble issue? I would certainly like to end up with a smoothly figured mirror with no bubble break-out on the surface.
I look forward to hearing from you.
