I accidently knocked over a ceramic bird bath while mowing he front yard. The result was that two small pieces about 2" x  3" in size broke off the top of the stand just under the bath portion. When I stood it back up and placed the bath back on top it rested on the stand with no problem and because the broken parts were so high on the stand their absence was not visible from a standing position. However, my spouse witnessed the accident and was not satisfied to have two parts of the birdbath unattached. The birdbath is a bit pricey so I thought about some type of repair rather than a replacement  birdbath.
