This ceramic sand, being aerated and fire-resistant, makes it easy to light a charcoal placed on edge. We recommend using a torch-type lighter.
A mixture of zirconium- and yttrium-oxides brought under pressure to temperatures in excess of 2000 degrees, this high-tech ceramic is ground using special tools with diamond crystals.
Its heat-resistant properties are unsurpassed. This sand is actually the shavings that result from the milling of fine jewelry and clockworks.
