Effect	According to the non-metallic mineral thermal conductivity and surface hardness of a quasi-linear relationship, based on this principle developed a drilling rig (test the authenticity of the diamond instrument), but also through the thermal conductivity to estimate some gem stones such as Mohs hardness Of the instrument 'Note that only measuring finished products, measuring the original stone'

According to the thermal conductivity of non-metallic minerals and surface hardness was quasi-linear relationship, based on this principle developed a drilling rig (test the authenticity of the diamond instrument), is also a Can be estimated by thermal conductivity of some gem stones and other Mohs hardness of the instrument 'Note that only finished products, can not measure the original stone' Please identify the Bass logo, as well as Bass security standard, be assured to buy!
