Do not use 502. Most 502 on the market is not strong enough to adhere to smooth surfaces, such as jade.

Never use ab glue, because it is not transparent glue. Although it is very strong, the effect is very ugly after being glued. You can try two kinds of dry glue, Antegu and quicktime. Antegu is around 5 yuan, and quicktime should be 13, 4 yuan. Those triangular bottles are quick-drying.

Or you can use transparent folds (zhe3, the word computer is problematic), jelly-like transparent colloid, which is easier to operate when standing. Even if it sticks to the jade surface, it can be wiped off before it is dry, and it is not afraid of leaving offset printing on the non-damaged surface due to operational errors. The pleating adhesive I am using now is Henkel Black & Decker transparent all-purpose adhesive, which feels good.
