Magnolia Serving dish with inside crack, repair advice

We have a Magnolia serving dish that has developed a small crack in the bottom on the inside. It does not show through on the bottom. Is there anything we can do to keep it from growing and can it be repaired easily? We recently purchased it on eBay and the crack did not show until now. The serving dish came from near Minneapolis and now resided in Las Cruces, New Mexico. (really different climate) Thank you and see you in July in Red Wing at the convention. Harley

Answer: Hi Harley

It could be repaired, but then you wouldn’t be able to use it. excessive heat could make the crack larger, (expansion). I doubt it will "grow" any larger than it already is. Maybe some epoxy could be used to fill the crack, but I’m not a repair expert. thanks, steve n rose
