B. Gold is found in native state
C. Zinc blende mainly contain zinc chloride
D. Copper pyrites also contain `Fe_2S_3`

Explanation

To determine which statement is incorrect among the given options, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze the First Statement:**
- **Statement:** Silver Glance mainly contains Silver Sulphide.
- **Explanation:** Silver Glance is known to be primarily composed of silver sulfide (Ag₂S). This statement is correct.

2. **Analyze the Second Statement:**
- **Statement:** Gold is found in native state.
- **Explanation:** Gold is often found in its native state, which means it is found in nature in its elemental form (Au). This statement is also correct.

3. **Analyze the Third Statement:**
- **Statement:** Jink Brand mainly contains Jink chloride.
- **Explanation:** The correct mineral for Jink Blend is zinc sulfide (ZnS), not zinc chloride (ZnCl₂). Therefore, this statement is incorrect.

4. **Analyze the Fourth Statement:**
- **Statement:** Copper Pirate also contains Fe₂S₃.
- **Explanation:** Copper Pyrite (also known as Chalcopyrite) is primarily composed of copper iron sulfide (CuFeS₂), and it does not contain Fe₂S₃. However, this statement is misleading as it implies a different mineral composition.

### Conclusion:
The incorrect statement among the options provided is the third one: "Jink Brand mainly contains Jink chloride."

### Final Answer:
The incorrect statement is: "Jink Brand mainly contains Jink chloride."
