Polysilazane‐derived ceramic coatings in the form of thin films (0.1 to 4 μm) — fabricated by dipcoating soda‐lime rods with preceramic polymer solutions, followed by pyrolysis — increased the strength of the glass rods. Strengths up to 414 ± 57 MPa were obtained, 2.3 and 3.3 times higher than the strengths of uncoated/annealed and as‐received rods, respectively. As‐received coated glass was stronger than coated annealed glass. Microstructural damage was not observed in the optimal coatings.
