Colourful Broken ceramics (Whitton TW3)

I am in need of lots of colourful broken ceramics….tiles… cups…plates etc. I am in the process of repairing my garden water feature that hasn’t survived the winter frosts. I’ve repaired the cracks and missing bits and now need to cover the exterior with ceramic bits. I did order some from Temu but sadly it’s nowhere near enough to finish the job and would cost way too much to buy the amount I need. If I can’t get enough I will have to resort to cement.
