A few times a year I'll teach a
small class how to carve a wax ring and then I will cast it in Sterling Silver.
Then in the 2nd class I teach how to polish your piece by hand. Below is
essentially what I teach in the first class published for the hobbyist.
Tips for Carving Wax.
Tips for Carving wax. By

So you've just bought your first block of jewellers blue wax and want to make
yourself a ring or pendant. Where do I start? You may ask yourself. Who is going
to cast it for me? When I first started, I basically stumbled my way through it.
The best place to find jewellers carving wax is at your local jewellery supply
store. Major cities will have one or more but for most of us ordering off of the
internet is the best option. Stick with a supplier in your own country, it'll
get to you faster and will less tax. Then hit a dollar store to get your carving
tools.
Simply put, lost wax casting is a process where the wax carving is melted out of
a mold and metal is poured/spun/vacuumed into the empty void. Then the mold
(sand or Plaster) is broken away to reveal the rough cast.
The fun part is carving the wax. The satisfying part is the look people give you
when you say you made it in metal.
10. Wax Carving Tips
1.Plan Plan Plan! In order to get your idea into reality, transform it one
dimention at a time; idea to paper then to sculpting the wax. Draw a few
sketches of what you want first.
2.Make time: In order to enjoy the process, make sure you have a well lit area
(daylight and north facing windows are best) and a flat surface to catch all the
excess wax. Also make sure you are undisturbed for several hours. A high
tabletop will cut down on neck and back strain.
3. Wax: The best carving wax to start with is the blue variety. Start by buying
a 1/4lb block or a tube with a pre-drilled hole, this saves a lot of time when
making a ring. Before jewellery supply stores the Egyptians and Mesopotamians
used beeswax to make the models. Our modern-day wax has paraffin and some
plastic in it to make it hard and raise its melting point.
4. Tools: The best tools to begin collecting are; A coping saw usually used for
softwoods, 2 files Course and fine, an exacto blade knife, a set of eye-glass
screwdrivers, and an empty mechanical pencil. If you have some experience
carving metal or other media, your old drill bits, dull burs and files will
still work very well on wax. A pipe tool is excellent for boring large holes in
wax too. The most unexpected source of wax carving burs are old alarm clocks.
The brass gears tend to be already connected to rods and are easily sharpened.
It’s almost as if they where made for your Dremel.
5.Keep it Simple: Great artists never start out producing master pieces and
neither will you. Keep your first half dozen wax designs very simple. It isn't
meant to sound discouraging but I find many of my wax carving students tend to
give up when they find their limitations on their first attempt. Making art
takes practice and is a learning process with each piece. I suggest starting
with a flat ring 1.5mm thick and 10mm wide with a simple design of a moebius or
anything easy.
6. Design on wax: Used your file to remove any excess material and then the fine
file to get a smooth surface to your wax. If you are carving a design into the
wax use the mechanical pencil to lightly score the lines. If you make a mistake
it can be easily filed off. A piece of paper towel works very well to smooth out
fine scratches on the surface of the wax too. Remember those lines are easier to
polish out on the wax then on the metal. Finishing the wax to the point that
there are as little scratches as.
7. Settings: If you are carving out a cabochon setting in wax here is a great
tip. Take a drill bit and grind the end flat. This will cut a perfect flat seat
for the stone. When used on an angle it can be used to cut a channel for stone
setting as well.
8. Weight: Remember someone is only going to wear a piece of jewellery if it is
comfortable. Rings for gents shouldn't weigh more that 15gms. The weight of the
wax will be a different ratio for each metal. For Silver multiply the weight of
the finished wax piece by 10.5 for 14k Gold the Weight is 13.6gm. Roughly
speaking it’s the specific gravity times the weight of the wax.
9. Your First piece: Don't use your first piece as a gift for your sweetheart.
Your first attempt is going to be very special and will be something that you
will keep forever to look back on.
10. Storage and shipping: Your wax is very very delicate. If it’s a ring DO NOT
let anyone try it on, even you. It will crack and then you’ll have to go back
and do all that work again. I find the best storage containers are empty film
canisters. Keep it in one of these until you cast it. They are so strong you can
use it to mail you wax to your casting house in a bubble envelope.
