POSCA works on most surfaces and is permanent on absorbent media such as paper and card, and can be removed from shiny surfaces with a scraper.
To make permanent:
- Paper/Card: No action needed - POSCA pigment will be absorbed into the fibres, making it permanent.
- Terracotta: Bake in the oven at 220°C for 45 minutes, then spray with clear varnish.
- Textiles: Iron on the reverse side
- Porcelain: Bake in oven at 160°C for 45 minutes, optionally spray with clear varnish.
- Metal: Spray with clear varnish.
- Glass: Bake in oven at 160°C for 45 minutes, then spray with clear varnish.
- Wood: Spray with clear varnish.
- Plastic: Spray with clear varnish.
These markers are commonly referred to as "Paint Pens"
