Utilise sparse layer of filler while pushing in to fill cracks and missing fragments
Let filler epoxy to cure for 12-24 hours (or longer) at a temperature of 75 degrees F or warmer. We place our filled projects in a 140 degrees F oven over night.
Placing under a lamp is another good option to optimize hardness for better sanding performance. Place at least 12" away from repair item to avoid overheating.
Apply Dremel EZ lock sanding disc 120 grit for sanding.
Use depression speed to avoid burn marks and utilize low-cal force per unit area. Go out the final x% or so for sanding by hand.
Warning - article of clothing protective eyewear
If Dremel is non available, sanding the whole job past manus (using dust 220 sandpaper) will take longer simply volition yield the same results
Repeat process on platter's other side

For seamless surface fill up the defects with PC-xi lightly
Wait for filler second layer to cure in a warm room (see more than above) earlier sanding
Sand second layer by hand with long strokes using grit 220, so grit 400 and stop with grit 3600. It may exist necessary to apply a third or quaternary layer if UV / light close inspection reveals more surface defects
Wipe with booze for better paint bond
Painting and Glazing
Airbrush over the repair line and taper off for smooth color integration to original background glaze.
