I've repaired a few as badly broken as in the pic. It's at, least to me, quite time consuming but usually rewarding. The biggest challenge is getting the checkering all lined up - if successful the rest is - "well easier". Even if it doesn't look that bad a first you can still land up with many pieces due to other cracks found along the way and need repair first. I put them back together even just to have a pattern for a future replacement. --- John
