6. To drill holes in glass or ceramic...

You need a diamond tip bit. I thought it would be expensive (since it has a diamond 🙄 ) but it really wasn’t. You need to drill very slowly. If you push to get through, it will crack. The drill bit will get extremely hot, and so will the surface, so you need to keep ice and ice water handy. It’s best if you are drilling something with a curved surface (like a plate, for instance) to keep a piece of ice directly on the surface to allow the water to run over the area where you are working as the ice melts. Often, this just isn’t possible, so you will need to stop frequently to cool both the surface and the bit. Be careful! The surface can quickly become hot enough to burn you! Once the surface has a slight indent, it becomes easier to keep the drill in place, but it also tempts you to push a bit harder and try to reach the other side more quickly. This impatience, I find, is often the cause of a break. It really takes a great deal of time and patience, and the continual cooling is the key.
