1. Put the teak wood produced in Panama, Ecuador, Malaysia, and Nigeria into a plate.
30cm × 5cm × 2cm or 30cm × 10cm × 2cm into the frost-free freezer at a temperature of -4 °C. Remove it after four days, then put it into boiling water and let it be about 100 °C. When the water temperature naturally drops to about 35 °C at normal temperature, put the sample on the outdoor balcony and dry for 3-4 days. This test is to be performed 4 times. As a result of the test, the first time in Africa, teak produced a broken head. For the third time in Ecuador, a broken break occurred.
final result:
1. Teak produced in Ecuador and Africa has broken, twisted and warped.
2. There is only distortion in the teak produced in Malaysia.
