Coated glass-based assembly

A glass-based assembly, comprising:

• a glass substrate comprising a surface, wherein the surface comprises a crack that extends into the surface,
• wherein the crack has a depth of at least 50 nm but less than 10 μm;
• wherein the glass comprises less than 40 mol % silica;
• wherein the glass substrate if uncoated has a first flexural strength, and wherein the first flexural strength is less than 500 MPa;
• and
• a coating coupled to the glass substrate and overlaying the crack,
• wherein the coating has a thickness between 20 nm and 1 μm;
• wherein glass of the glass substrate has a crack-onset strain, and wherein stretching of the coating to the crack-onset strain of the glass does not fracture the coating;
• wherein flexural strength of the coated glass substrate is a second flexural strength that is greater than the first flexural strength;
• wherein the second flexural strength is at least 100 MPa greater than the first flexural strength.
