The Self-Promotion Method
Using the same tree species to impersonate Burmese teak. The market mainly uses names like "Indonesian teak," "African teak," "South American teak," "Brazilian teak," "Malaysian teak," "Nigeria teak," and "Guyana teak." In reality, even if they belong to the same species, their quality and price vary greatly depending on their origin. Some are not even teak at all, resulting in even greater price differences. These African and American teaks, due to different climates in their growing regions, have shorter growth cycles, maturing in just 10 years. Their oil content is relatively low, losing the rich oil content characteristic of teak, and the material is prone to cracking when dry. Therefore, flooring made from "African teak" or "South American teak" is not actually genuine teak flooring.
The Substitution Method
Using tree species with similar or nearly identical grain and density to impersonate Burmese teak. The most common example on the market is blackheart wood being used to impersonate Burmese teak, making it difficult for laypeople to distinguish.
False Naming Methods
Teak is a precious wood, and many miscellaneous woods on the market are labeled "**Teak" to increase their value, such as "Indonesian Teak," "African Teak," "South American Teak," "Golden Teak," "King of Teak," and "Teak Sandalwood," etc., which actually have nothing to do with genuine Burmese teak flooring. Even worse, some are marketed as "Thai Teak," unaware that due to logging bans in Thailand, Thai teak is almost non-existent in the market.
Identifying Genuine from Fake Teak Flooring
Consumers who understand these three methods of counterfeiting teak flooring can be more informed, but they still need to be careful when purchasing. Below are some methods to distinguish genuine from fake teak flooring. Most of these methods are based on the premise that the board is unfinished or the back is not sealed with lacquer. If it is fully sealed with lacquer and some workmanship is altered, it becomes very difficult to distinguish.
Examine the Grain: Genuine teak flooring has obvious dark lines and oil spots; fake teak flooring either has no dark lines or the dark lines are shallow and scattered.
Touch Test: Genuine teak flooring feels smooth and very delicate to the touch, as if it has been soaked in oil; fake teak flooring is noticeably rough.
Smell Test: Genuine teak flooring emits a distinctive fragrance. If there's a large quantity of teak or the entire showroom is made of teak, you can smell this fragrance as soon as you walk in. This fragrance is very pleasant. Fake teak flooring either has no fragrance or an unpleasant odor.
Weight Test: Genuine teak flooring has a density of approximately 0.67 to 0.73 g/cm³, lighter than rosewood but heavier than hemlock, giving it a moderate weight. Fake teak flooring is generally heavier.
Water Test: Drop a drop of water onto an unpainted area of teak flooring. On genuine teak flooring, the water will bead up and not seep in. On fake teak flooring, the water will seep in, either quickly or slowly (teak is rich in oils, and water and oil are immiscible, so water won't be absorbed into beads on genuine teak flooring). When wiping water stains with a paper towel, you'll find that water on genuine teak flooring dries quickly without leaving a trace because the surface is oily and smooth; however, water on fake teak flooring, due to its rough surface and the fact that it has absorbed the water, is difficult to wipe dry and leaves paper scraps.
Sixth, examine the sawdust. This is relatively easy to identify during the flooring installation process. Genuine teak sawdust has a heavy oil content and feels soft to the touch, while fake teak sawdust is dry and loose.
Seventh, water immersion. Immerse the flooring in water for 24 hours and observe the changes. If there are no changes, it is genuine teak flooring; if it warps, swells, or deforms, it is fake teak flooring.
Eighth, fire test. This is a destructive test. Most stores have small samples of teak flooring. Take a small piece of dry flooring and burn it. Genuine teak flooring emits thick and abundant smoke, while fake teak flooring produces less.
Quality vs. Quality. Generally speaking, the richness of teak's unique iron, oil, and aroma are key criteria for judging the quality of teak flooring! The higher the oil content, iron content, fiber density, and aroma of teak, the better the quality of the teak flooring! These characteristics typically depend on the origin, tree age, part of the wood used, and manufacturing process.
Natural Forests vs. Plantation Forests Teak flooring made from natural forests and plantation forests differs significantly in quality. Natural forest teak takes at least 50 years to mature, with a slow growth period, resulting in higher density and hardness. Plantation teak, on the other hand, is grown rapidly using artificial techniques, shortening the growth cycle. It typically matures in just over ten years, and thinning begins in the sixth year after planting. Due to differences in environment, climate, and soil, the growth cycle of plantation teak is significantly shortened. This results in teak having lower oil content, less or no mineral lines, greater shrinkage, susceptibility to deformation, and poor corrosion resistance; the wood fibers are coarser, with lower density and hardness, significantly reducing stability and toughness, and almost no teak aroma.
Natural forest teak resources are precious and scarce. In the late 1980s, the market price of Burmese teak increased by 10% to 15% annually. Therefore, establishing teak plantations has become a global investment hotspot. Southern my country's Hainan, Guangdong, Fujian, Guangxi, and Yunnan provinces have been planting teak trees for some time, with Guangdong being the first to introduce and plant teak in Guangzhou in 1914, boasting nearly 90 years of cultivation history. This explains the increasing scarcity of natural teak resources, while the market offers a large supply of teak flooring at very low prices. However, compared to the natural fragrance and rich oil content of natural forest timber, plantation-grown teak appears much coarser.
