We use top-quality fire-proof and heat-resistant glue and fibre-glass cloth with good durability to make the mortars with clear and tidy appearance. It can be an evidence that the cost of our glue and fibre-glass cloth is over 60% and 30% respectively higher than other factories'.

We use a different way to set up their bottoms. We believe it's not necessary for ours to have such thick bottoms. Some factories produce thick bottoms on account of their different skills, which we don't like to adopt for quality.

Suggestion for storage: they should be stored cleanly in dry area. So after use, they should be cleaned inside and outside. Open-air storage should be avoided for long-term use.
