Ceramic Streak Test Plates – Pack of 10
Packets of ten ceramic streak test plates, only sold in white.
Used for performing ‘streak tests’, these unglazed ceramic tiles are an ideal tool for helping identify gemstones and minerals.
White plates are typically used for darker materials, but it is worth noting that some dark materials do have light streaks!
These plates measure 50MM x 50MM approximately and are around 3-5MM thick.
We sell a range of other jewellery, lapidary, and mineralogical related tools; please see our main tools section.
