How to check the quality of color washbasin sink

OVS CEO told you how to check the quality of color washbasin sink.

Our factory mainly designs and produces sanitary ware products.

We have mainly two steps to check the quality of bathroom wash basin. First, scrape gently with a strong thing. The low quality table top wash basin will be scratched and glaze appears off. Our high quality wash basins are scratch resistant.

Second, burn with fire. The glaze of low quality wash basin will be off after burning. Our high quality basins are fire and heat resistant.
