1. Shard characteristics
Before talking about products, let's talk about the properties of ceramic shards. Ceramic shards are agglomerates of grains of different origins:
residual crystals of quartz, potassium feldspars or soda-lime feldspars (plagioclase) and mica from the original rocks;
new small crystals formed during firing: quartz, mullite, hematite, calco-aluminum silicates (e.g. pyroxene, gehlenite).
These crystals are bound together by the glassy matrix of the melting elements. The theoretical density of this material is around 2,600-2,750 kg/m 3 (the density of quartz is 2,650 kg/m 3 , but that of hematite is 5,250 kg/m 3 ).

Definitions
Some of the definitions used in the main article are given below.
The cation exchange capacity (CEC) of a soil is a measure of the total number of sites available for cation exchange, or the total number of exchangeable cations, or the number of negative sites in the soil matrix. The unit is the milliequivalent per 100 grams (mEq/100 g) of soil, or the centimole of positive charge per kilogram, where...
