1. 檢查：查看仿古琉璃瓦的包裝箱上是否有廠名、廠址以及產品名稱、規格、等級、數量、商標、生產日期和執行的標準。檢查有沒有出廠合格證、產品有無破損，箱內所裝產品的數量、質量是否與包裝箱上的內容一致。
1. Inspection: check whether there is the factory name, address, product name, specification, grade, quantity, trademark, production date and executive standard on the packaging box of antique glazed tile. Check whether there is factory certificate, whether the products are damaged, and whether the quantity and quality of the products in the box are consistent with those on the packing box.
2. 看：質量好的仿古琉璃瓦面應平滑、細膩，光澤晶瑩亮麗，亞光釉柔和舒適。在充足的自然光線或日光燈照射下，將仿古琉璃瓦放在1米遠處垂直觀察，應看不到明顯的釉面缺陷，產品無色差
2. Look: the surface of antique glazed tiles with good quality should be smooth, delicate, shiny and bright, and the matte glaze should be soft and comfortable. Under sufficient natural light or fluorescent lamp irradiation, place the antique glazed tile at a distance of 1m and observe vertically. There should be no obvious glaze defects and the product has no color difference
3. 聽：可以輕輕敲打仿古琉璃瓦，細聽其聲音。質量較好的產品，聽聲音清脆，說明仿古琉璃瓦密度和硬度高，質量好。劣質產品，敲擊時會發出“空空”的聲音
3. Listening: you can gently tap the antique glazed tile and listen to its sound carefully. The products with good quality have a crisp sound, indicating that the antique glazed tiles have high density and hardness and good quality. Poor quality products will make an "empty" sound when knocked
4. 試：要選擇吸水率低的仿古琉璃瓦，可以測測它的吸水率，吸水率越低，代表仿古琉璃瓦的內在穩定性越高，也就越適合濕氣或水分含量較高的空間。
4. Try: to select the antique glazed tile with low water absorption, you can measure its water absorption. The lower the water absorption, the higher the internal stability of the antique glazed tile, and the more suitable for the space with high moisture or moisture content.
