My restoration talents are just basic...
Since I sometimes have occasion to sell one or more pieces that may have some restoration done on them, I thought I should mention a few things about my restoration/repair jobs.
I only restore items that I sell or for my own collection. I do not offer the service to the public and never will. I have not the inclination, time, training or space to store restoration projects.
I am not trained as a professional restoration artist. I do not claim any of my restorations to be of professional quality.
I do not guarantee or warrant any restoration to be permanent! Non-fired restorations may fail with time or mis-handling. I say *may* because most will last for many, many years of enjoyment. But I cannot say they will last forever! That said, I have had no reports of any serious problems cropping up with my restorations.
I do not guarantee my restorations to be absolutely invisible! Sometimes I will achieve that goal or get quite close, but not always. I simply desire to do what I can to put the piece back into nice display shape for the new owner's enjoyment. My work may or may not hold up to close inspection at a live show. My efforts will at least make the damage to a piece considerably less noticeable than it previously was.
I'll generally try to take a picture of damage(s) before restoration. You probably should consider SAVING any such "Before" pictures shown as a personal reference on what exact damage the piece incurred and as a reminder of just what areas need careful handling! I also recommend saving the written description of the damage as reference.
On finish coatings
I try as much as possible to limit any finish coatings to as near the break location as I can get, allowing for the need to blend paint and coatings with the original finish.
Although this may render a given repair potentially more detectable, since the entire piece isn't sprayed, it also makes it less likely that cosmetic problems will surface in the future. Glaze is pretty tough. Sprayed finishes are less so. There is potential for a sprayed finish to "crawl" on a glossy surface with time. By not spraying the entire piece, I limit both that risk and the risk of scratches to the sprayed finish eventually building up with time and handling.
Handling the restored piece
You will want to be careful and try to keep pieces dry. While the assorted finish coatings I use tend to be fairly resistant to water, they are not necessarily completely impervious to it! The paint underneath will usually be acrylic and acrylics are not proof against moisture damage. If you need to remove soil, go lightly with a soft lightly dampened cloth on any restored areas. Do not use solvents or abrasives!
Restored pieces should, if possible, be kept from extreme temperature changes. Glues, paint and finishes can be sensitive to extreme heat. Restored areas with paint and/or finish coatings will also be somewhat sensitive to scratching. Just be as careful as you always would with any breakable and chances are, you'll enjoy the restoration for years!
