So, if I understand correctly, I take a piece of known quartz and try to scratch the piece I'm unsure of? If it leaves a mark, the suspect piece is softer (or the same as?) quartz. If it doesn't leave a mark, it's a harder mineral (and I'd have to figure out exactly which 'harder mineral' it was at that point). Do I have this right? Thanks again-- Yakker
You can buy Mohs Hardness scratch kits . This will help you start to narrow down the process a bit G.L
Hey rodoconnor, where is the best place to buy the scratch kits. I saw a 10 piece set on Ebay but if I remember right it was 97.00. Hope I can find the set lower than that. Thanks.
Thanks guys. I have most, if not all of the things that seem to be in a test kit (glass, copper scrap, nails, unglazed porcelain, dental pick, mag. glasses). And I just found my book on rocks and gems which has a hardness scale. Am I missing something? Some secret thing that's in a kit that I'm not seeing? Thanks again- Yakker
Yakker you are fine, I have been looking for a scratch test kit that is less expensive than Ebay and they were trying to help. I have quartz to scratch with that is 7 on Mohs scale of hardness but I was wanting to find the whole kit.
Well, I guess depending on how small and/or technical you're needing, here's this-
