Here’s a concise overview. 1) Vegetable-tanned leather Premium and specialty goods (e.g., saddlery). Tanned with natural tannins from wood, bark, and gallnuts. Natural grain, soft matte glow, flexible feel, high absorbency; develops a rich patina. 2) Uncoated / bare leather (aniline, pull-up, waxed) Fashion accessories, clothing, designer footwear. Minimal or no protective topcoat. Open-pored, absorbs moisture quickly; prone to staining and fading. Pull-up/waxed treated with oils & waxes → soft hand, gentle sheen. 3) Dyed & protected (pigmented, embossed, semi-aniline, vintage, bicast) Furniture, footwear, outerwear. Protective film or pigment layer; embossed textures common. Vintage has delicate finish; bicast has dense PU/PVC surface. Easier maintenance, low absorbency. 4) Suede & nubuck Velvety nap created by sanding. Suede—thicker, fluffier nap; nubuck—fine, more wear-resistant. Both are absorbent and require dedicated care to avoid staining and fading. 5) Synthetic (faux / eco) leather PU/PVC layer on textile base. UV-stable and non-absorbent but can feel cold or overly glossy. Deep creases and delamination may occur over time. Step-by-Step: Identify Your Leather Test on a discreet area first. Combine observations for accuracy. 1) Visual inspection Suede & nubuck: easy to spot by velvety nap and high absorbency. Smooth or embossed surface can indicate dyed, aniline, or semi-aniline—confirm with the tests below. Some leathers are easy to identify visually; others require additional checks. 2) Protective coating test Lightly scratch with a fingernail in a hidden spot: • No mark → protective topcoat (often pigmented or coated).• Visible mark → likely aniline / uncoated. Pros: Use a magnifier to inspect grain texture and finish clarity. 3) Water absorption test Place a small drop and rub gently: • Absorbs quickly → aniline / pull-up / waxed.• Beads on top → pigmented / semi-aniline / bicast. Suede authenticity: synthetic suede is water-repellent (water sits on top); natural suede absorbs, darkens, and stiffens. 4) Flex & shine test If it scratches and absorbs, bend slightly: pull-up/waxed lightens on the fold; aniline does not. If it doesn’t scratch/absorb and has soft matte glow → pigmented. Harsh plastic-like shine → likely bicast. Pro Tip For coated and synthetic leathers, the LeTech Leather Care Kit is a safe, universal choice. For suede & nubuck, use the dedicated Suede & Nubuck Care range.
