I have a pan in which the pastel has crumbled can I reconstitute or re-press this.
Thank you for your enquiry.
Fixing a pan pastel:
The most popular method is to use Isopropyl alcohol (rubbing alcohol)
You can either remove the broken pastel from the case and grind to a fine, even powder, add the Rubbing alcohol to create a paste and return to case until dry.
Add the Isopropyl to the case and make a paste and allow to dry.
If the pastel still has some cracks you can repeat by adding mor Isopropyl alcohol and gently patting until a smooth consistency.
