Hi. I have paved a 14 m2 area. I wondered about adding fine coloured glass cullet to the jointing product, to give the paved area a bit of sparkle. Glass cullet is used for making garden ornaments, amongst other things, akin to mosaics. Is there a product which will accept added glass cullet? Thank you.

It's a bad idea - you are effectively diluting the jointing medium, weakening it ad ultimately compromising it.
The resin mortars are formulated with precisely sufficient resin to bind the enclosed aggregate. If you add more aggregate in the form of cullet, you reduce the amount of resin binder available for the intended aggregate.
To achieve what you want to do, I'd suggest using a resin binder, such as those available from SureSet, and mixing up your own aggregate base of, say, black foundry sand (from Gardside Sands) with your chosen cullet.

Thank you for a very helpful response.
I have been in touch with SureSet, and I sent them a photo.
I am waiting for their reply on how much binder and cullet I need.
Cheers.
