It’s entirely up to you when you bake your design applied with the edding 4200 porcelain brush pen. It can be much later than our recommended drying time of 15 minutes – even one or two days later is fine.
Just take care that your design doesn’t get scratched in the meantime and doesn’t smudge by getting wet. It would be a shame if your work of art became damaged simply because of not heat-fixing it straight away.
