I deorated a dummy cake with royal icing and have kept it under a glass box. I live near the seaside so there is a lot of humidity out here. I saw some fungus on the royal Icing flowers because of the humidity and im scared the flowers will losse color and shape.

Is there any way I can preserve this cake?

please help!!!!!!

use icing not real that is for decorated the dummys im not sure the name but in american cake decorating has some company sell this icing

maybe it's because you've got it under a glass box. Perhaps the moisture from the icing is now trapped in the glass box. Mold and fungus grow in moist, (usually dark) places.

My dummies are decorated in regular BC, they sit out uncovered and I've never had discoloration, bugs or mold/fungus. Some of my dummies have sat out for close to a year.

What you thought was protecting the cake sounds like it's the culprit for fungus growth on your cake.
