How to Make a Copper Ingot
The first thing that is required to make a copper ingot is to find a copper ore that is mostly available on the beaches, and other biomes at y level 0-96 but mostly at 47-48. After finding you need to mine it by a stone pickaxe or any other of higher level.
The next thing that you need is a furnace and any fuel source that you can get such as a coal, wooden log or planks. Furnace can be made by placing 8 cobblestones on the crafting table and these stones are also not hard to find and can be mined using any pickaxe.
Now place and click on the furnace and after that you will notice some slots will be displayed in which you need to place the copper ore on the top slot and a fuel on the bottom slot whereas the result can be seen on the right slot.
How to Find Amethyst
You can find amethyst in the caves or cliffs at around or below y level 70. You can also find these blocks on the beaches or oceans close to the shoreline and after finding them you can mine them using an iron or any other higher pickaxe.

Conclusion
Spyglass in Minecraft is used for zooming purposes so that a player can see clearly at a longer distance which is not possible normally. When you are wandering around in different biomes, this is very useful since you can improve your vision and can easily locate valuable resources or mobs that aren’t visible with the naked eye.
