Afghanite, (Na,K)22Ca10[Si24Al24O96](SO4)6Cl6,[1] is a hydrous sodium, calcium, potassium, sulfate, chloride, carbonate alumino-silicate mineral. Afghanite is a feldspathoid of the cancrinite group and typically occurs with sodalite group minerals. It forms blue to colorless, typically massive crystals in the trigonal crystal system. The lowering of the symmetry from typical (for cancrinite group) hexagonal one is due to ordering of Si and Al.[1] It has a Mohs hardness of 5.5 to 6 and a specific gravity of 2.55 to 2.65. It has refractive index values of nω=1.523 and nε=1.529. It has one direction of perfect cleavage and exhibits conchoidal fracture.[3] It fluoresces a bright orange.

Waarom overbieden gebruikers zichzelf?
Wanneer een bod wordt geplaatst, is dit het maximale bedrag dat een persoon bereid is te bieden voor het product. Ons systeem zal dan automatisch bieden namens de bieder, waarbij het bod stapsgewijs wordt verhoogd tot het maximum om hun positie als hoogste bieder te behouden.
Wanneer er een pictogram is dat 'Automatisch bod' aangeeft, betekent dit dat ons systeem actief biedingen plaatst voor de bieder op basis van hun maximale bod. Dit kan lijken alsof bieders zichzelf overbieden, maar het is gewoon een resultaat van het systeem dat het bod bijwerkt om de maximale limiet van de bieder weer te geven.
