Engraving glass is a lot of fun and it’s
easier than you might think. So let me show you what you need and how to
do it. I’m using a standard rotary tool with a
flexible shaft extension. The extension makes it a bit easier to do
more detailed work, but you can also make do without. Since glass is very hard, I’m going to be
using a set of diamond coated bits. There are a lot of different bits in this
set, but a good place to start is with a ball shaped one. The engraving will cause a lot of fine glass
dust, so make sure to wear a dust mask and eye protection! I’m using poster tacks to support the piece
that I’m working on. This will keep it stable without me having
to hold it. I’m going to practice a bit on an old wine
bottle. I set the Dremel at a medium speed and started
engraving. For now, I’m just freehanding a design. I quickly figured out that you don’t have
to push down into the glass a lot, a light touch is all it takes. It’s all about letting the tool do the work. One direction of engraving will work better
than the other. This is because of the rotation direction
of the tool. For me, I did the best cutting when pulling
the tool towards me, so I drew lines onto the glass that way and lifted the tip up in
between. The engraving creates a reasonable amount
of glass dust, which can make it difficult to see what you’re doing. Keep a wet cloth and a bowl of water nearby,
so you can wipe away the dust regularly. This will make it look like your design is disappearing,
but don’t worry, once you dry the glass it will reappear. Now that I have a feel for the tool, I can
move on to making a more detailed design. I won’t be freehanding this one, so I printed
the design, cut it out and taped it to the inside of the glass. This way, all I have to do is trace the design
onto the glass. I switched to a smaller ball shaped bit to
allow for the finer detail. I changed the orientation of the glass several
times along the way to make the engraving a bit easier. For the final details I switched to the thinnest
bit that I had, which allowed me to write the tiny letters on there. Finally, I used the ball shaped bit again
to add random stars all the way around the glass to make the Tardis look like it’s
floating through space. In some cases it won’t be possible to tape
your design to the inside of the glass, like with this small carafe. So I took some wide painter’s tape and covered
the printout with it, making sure the pieces overlap. I then cut out the inside of the design, leaving
me with a silhouette. I carefully peeled the tape off the paper
and placed it onto the glass. I’ll still have to freehand the branches
and the leaves, but being able to trace the outline definitely helps a lot. Alright, that’s it for this one. I really enjoyed engraving stuff, so I’m
going to be trying this on a couple of different materials, probably metal next. But we’ll see. Let me know if you liked this video by leaving
