1. A- Zincite, B - Galena
2. New Jersey - Franklin and Sterling Hill Mines
3. Different ways, but one is the CZ method where a seed crystal of the mineral is dipped in molten feed material and eventually the molten material crystallizes forming a new part of the crystal.
4. Lead
5. Metallic/Dull
6. Crystal Detector

You got them all! Your turn.

Mineral A is Zincite
Mineral B is Galena
crystalline Zincite found in NJ?
I don't know this, but it probably has something to do with heating zinc
Galena is the primary ore for Lead
Galena has a bright metallic luster
I had to search this one up. They were used to make the crystal detector or "Cat's Whisker" radio detector.

I gotta go now, I'll probably be back in around 15 hours to continue if no one else has already.

(oops i responded when someone already did, my bad)

I'll continue with some questions.

1. Identify specimen A (blue)
2. Identify specimen B (dark)



3. Would either of these minerals be good for making jewelry? Explain why or why not for each.
4. Both of these specimens are part of what mineral group? Be as specific as possible.
5. Match each of these traits with mineral A, mineral B, neither or both:
a. can be found in Switzerland
b. fragile
c. usually harder than quartz
d. denser than native copper
