White rectangular ceramic plate designed to clearly observe the streak colour of minerals and pigments. With dimensions of 5×5×0.5 cm and a weight of only 38 g, it is a very compact accessory that fits easily in a pocket, field pouch or sample case.

It is especially useful for quick identification of sulphides, oxides and other minerals, both in geology fieldwork and in the laboratory or classroom. The white surface provides a strong contrast with the mineral streak, making it easier to compare with colour charts and identification guides.

Ideal for:

• Geology and Earth science field kits

• Laboratory and teaching activities

• Collectors and hobbyists checking samples at home

As with any ceramic piece, it is advisable to carry it protected to reduce the risk of breakage.
