Technical description

Date palm seeds are ground into a fine powder, compressed into a disc, and treated with sodium hydroxide and sulfite at 100°C for 12 hours to remove lignin. The disc is then bleached with hydrogen peroxide, making it transparent.

Simplified description

This process transforms date palm seeds into transparent glass-like sheets. It involves grinding the seeds, compressing them into discs, removing unwanted materials, bleaching them, and finally hardening them with epoxy resin to make them clear.
