What is coming through my tiles???

Post by Max2022 »

Hi all

I have no idea what this is coming through the tiles, it can be wiped away but still keeps coming back.

Any help greatly appreciated 🙏

Difficult to say from pictures but it looks like an imperfect glaze on the tile and the biscuit, or core is breaking out the fissures. Have a look through magnification to see if that gives you any hints. I have never seen that before?
