This set of tests is aimed at understanding the effect of different finishes on Kotibe.

A set of 4 solid samples (from “A” to “D”) were employed; unfortunately, these do not start from very similar PZC values. All samples were sanded to 320-grit.

A special thanks goes to company Veleca for supporting us with finish samples.

We tested these finishes:
Sample A: Veleca Nitrolux (thinner based ketone resin – classic furniture finish)
Sample B: Veleca Olio per Teak (Tung oil based – exotic wood finish)
Sample C: Nitrocellulose spray lacquer (NCL)
Sample D: Blonde Dewaxed Shellac “Medium” (2 parts in 13 parts of Alcohol)

It was concluded that:
1) Good chatoyance (> 20 PZC) can be achieved with all tested finishes, with Shellac providing the worst results
2) All these “clear” finishes significantly darken the surface

Tables below summarize the results in terms of chatoyance (PZC):
