How does the word ‘no-vex’ relate to the word ‘honest’?

In the past, European pottery was very valuable. Good pottery must not have any cracks. If there is even a small crack, the value of that pottery will immediately drop. However, there is a way to hide the cracks smoothly. Just apply a little white wax and it can cover the cracks smoothly. Therefore, dishonest merchants will use this method to deceive and sell fake pottery at high prices. The word no wax comes from the word “sit- cere” which means honesty. What  is more interesting is that the Latin origin comes from Ancient Greek. If you look at the root word, it means ‘sun tested’ or ‘sunlight shines’. To the eyes of the general public, a labeled pottery may look perfect, but only an expert can know the truth by looking at it in the sunlight. Experts say that if you hold a pottery up to the sunlight, you will see the ex-mutt. In another way, if you hold a pottery up to the sunlight and there is no wax, it means honesty. Beauness started with this vision as well.
