I cooked steaks last night and this morning this alien goo appeared on the outside of my green egg after I started it back up to make Mother’s Day lunch. What is this? It seems to wipe right off on the surface, but it also seems like it’s secreting from within the ceramic. Anyone seen this before? How screwed am I?

For background, the Egg is about 15 years old. Never noticed this before. We did recently just move and this was the second or third time I cooked on it after a long period of non-use (approx. 6 months).
