Test Glass
Turn on the LeadLight
Spray the reagent
Lead can be compressed inside the glass: in this case, roughen the surface with an engraving pen
Spray or drop reagent where you engraved the glass
Notes:
- Alternatively, you can use sanding paper to roughen the surface. However, this tool is not recommended as it would create a lot of dust.
- Always keep the reagent spray and dripper in an upright position when not in use to avoid leakage.
