Management of fine crack

Fine cracks

* These white stripes (stone veins) are not fine cracks
but merely the natural patterns of stones.

Our products are made by processing natural stone without any chemical treatment. It is made of natural stone, so fine cracks are natural stone vein phenomenon.
Products that are heated directly by fire, such as stone pots and stone roast pans, may expand due to heat during the first direct fire, resulting in fine cracks, and water or oil may leak out.

How to Manage
Fine Cracks

Avoid rapid heating or rapid cooling to minimize the occurrence of fine cracks.

Step 1.
Knead flour and water (vinegar) like a paste.
Step 2.
Put in a stone pot, roast pan or other pot so that it soaks in between the fine cracks and dries, then heat it for '20~30 minutes' on the lowest heat.
Step 3.
When the stone bowl cools, wash with warm water. Eating bibimbap is also effective limits fine cracks.
Step 4.
A stronger stone bowl through fine crack management.
