Is the glass affected by heat, steam and water?

No, DECO GLAZE Colour Coating is guaranteed to adhere to glass and is unaffected by steam, boiling water and heat. The glass is toughened where needed, for example a splashback behind a hob. Toughened glass
– also sometimes referred to as tempered glass – is up to four times stronger than ordinary annealed float glass. If broken, it disintegrates into small fragments with dulled edges that are unlikely to cause serious injury.
