Coated glass element

A coated glass element, comprising:

• a glass surface;
• and
• a coating that coats at least part of the glass surface, the coating comprising at least one layer and being formed from a precursor that comprises a siloxane, the at least one layer of the coating fulfills the following parameter:
• [Si2C5H15O2−]20/[Si2C5H15O2−]80≥1.0;
• wherein [Si2C5H15O2−]20 are counts of [Si2C5H15O2−] ions, measured by a time-of-flight secondary ion mass spectrometry (TOF-SIMS), at 20% of a time a sputter gun beam needs to reach the glass surface;
• and
• wherein [Si2C5H15O2−]80 are counts of [Si2C5H15O2−]80 ions, measured by a TOF-SIMS, at 80% of a time a sputter gun beam needs to reach the glass surface.
