ESKX Agate Coasters 4-5" Diameter (Blue)

Description

NOTE:Our Blue Coasters are Dyed to Highlight their Stunning Features These Brazilian Agate Coasters from ESKX are expertly crafted from whole agate rock. Agate is formed from quartz crystals of varying sizes aggregated naturally in one rock. Due to the nature of crystal growth, all coasters will be unique. While quartz has excellent thermal shock resistance, an aggregate contains grain boundaries susceptible to failure from extreme temperature differences (thermal shock). Care should be taken to avoid exposing your coasters to an immediate extreme difference in temperature. Our Agate coasters can be cleaned as you would clean a glass table or window. NOT DISHWASHER SAFE. Glass of juice pictured NOT included.
