how jewellers Blowtorch work

Gas blowtorches, even professional ones, are fairly simple constructions. Their basic design has not really changed in the past century. A professional blowtorch usually consists of a cylinder of fuel gas, a cylinder of oxygen, two gas regulators, two hoses, the torch and the tip.

Regulators on the cylinder heads control the pressure and flow of the gas. Adjusting them to the appropriate pressures is essential to preventing explosions. A regulator has two gauges: the high-pressure gauge reads the gas pressure in the tank, and the low-pressure gauge reads the gas pressure for delivery to the hose and torch. Learn more about pressure and how to measure it in How Tire Pressure Gauges Work.

The hoses that connect the steel cylinders to the torch are made of strong, flexible material, usually rubber. To avoid confusion, the hose containing oxygen typically is green, while the fuel-gas hose is red.valve2

The torch head has two needle valves, which are circular knobs that control the flow of either the oxygen or the fuel gas. The tip attaches to the torch head, and people change it according to the task being performed and the gas used. When a blowtorch is used for cutting metal, an oxygen pipe sends an additional stream of oxygen directly to the center of the flame, increasing its intensity. Finally, an igniter, or pilot light, much like the one on a gas stove, actually lights the torch. It’s a bad idea to ignite these torches with a cigarette lighter or a match because of the dangerously high temperature of the flames.

What prevents this thing from blowing up in your face? Well, the following attachable safety devices usually come standard on blowtorches sold today, but can also be sold separately.

Check valves attached to the regulators and the torch head will help to prevent the gas from flowing back through the hose or cylinder. The pressure in the hose should always be greater than the pressure in the torch head. If this changes and the pressure in the torch head surpasses that of the hose, then the check valve closes, shutting off the gas supply.

The flashback arrestor fastens to a regulator and typically consists of both a check valve and a flame barrier, which allows gas through but not flame. These arrestors prevent flashbacks, which we’ll discuss in the Lighting Up section.

Next, we’ll take a close look at the different gases blowtorches consume to attain these high temperatures.20131028_091707

Two types of igniters light blowtorches. In the piezo-electric igniter, pulling the trigger launches a hammer against special crystals, which then produces electric voltage and sparks. To find out about more of the various and unexpected uses of piezoelectricity, read about how the lighter in a bbq grill works. A friction igniter, which looks like an oversized safety pin, creates sparks by scratching special crystals when squeezed.

       Lighting Up: Using a Blowtorch

20131028_091820 After gearing up, a welder follows certain steps to turn a blowtorch on and off. As different torches have different safety procedures, refer to the specific manufacturer instructions before operating a blowtorch. A step-by-step procedure for turning on an oxyacetylene torch goes like this:

  1. Turn the acetylene regulator screws out to allow gas through and adjust the working pressure of the gas.
  2. Open the acetylene cylinder slowly, but only a third to a half turn. This allows for the release of acetylene.
  3. Open the acetylene needle valve on the torch head and adjust the acetylene regulator to the best working pressure (about 5 psi).
  4. Close the acetylene needle valve. This stops the flow of acetylene so that you can start the oxygen safely.
  5.  Turn oxygen regulator screws out so that oxygen can flow and you can adjust the working pressure.
  6. Open the oxygen cylinder valve slowly until completely open. This allows for the release of oxygen.
  7. Open the oxygen needle valve on the torch head. At this point, you can adjust the oxygen regulator to attain the best working pressure (about 5 psi for welding purposes).
  8. Close the oxygen needle valve so that you stop the flow of oxygen and can later light the gas safely.
  9. Pause and test for leaks in any of the valves and hoses.
  10. Open the acetylene needle valve again so that the gas is released and it can light.
  11. If the blowtorch is not equipped with an internal spark ignition device, light the acetylene with a friction lighter held about one inch from the tip.
  12. Wait for the black smoke to stop and slowly open oxygen needle valve. Adjusting the oxygen needle valve affects the type of flame you get. A neutral flame is commonly preferred and is made up of equal parts acetylene and oxygen.

     20131028_091719  But to switch off the torch, you follow these steps:

  1. To switch off the torch, close the acetylene needle valve first, which extinguishes the flame.
  2. Close the oxygen needle valve. This cuts off the flow of oxygen.
  3. Turn off the acetylene cylinder valve and then turn off the oxygen cylinder valve. This stops the release of the gases from their cylinders.
  4. Open the acetylene needle valve until gauges read zero pressure and turn out the pressure adjusting screws on acetylene regulator. Close the acetylene needle valve. This drains any remaining acetylene pressure left in the hoses and torch.
  5. Open the oxygen needle valve until gauges read zero pressure and turn out pressure adjusting screws on oxygen regulator. Close the oxygen needle valve. This drains any remaining oxygen pressure left in the hoses and torch.

Basic Tools Necessary In the Jewellery Making Process
Here are tips and tricks  which you can learn the trades from a jeweller who has been in the industry for 13 years, Mark Burgess.

First, we are to go through the bench where we are going to learn some of the tools and few of the more advanced tools.

Im are also giving you some tips that could help you get to your jewelry goal quicker. The very first tool ive got was this vernier gauge. It is an electrical one. All you have to do is just press one button and it will measure everything up really accurately and you definitely need one of these. You can pick them up quite cheap now and you can actually get a smaller one for about 20 to 30 pounds and it’ll probably do for now. you won’t be doing massive pieces so that’ll probably suffice for now until you feel that you need a bigger one.

The four basic needle files you need are the following:

1.) When you first start  you will need the safety back.
-This needle file has teeth on the front side and not on the back hence it is called safety file. Being called so, you can strike it to different surface on the right side.
2.) Second, is a free square 
-which is basically a triangle which allow you to do same thing. It can get into nice little angles with that nice  sharp tip which does some nice clean work.

Resizing a ring to make bigger

In these videos I am going to show you how to resize a ring, resizing is usually done to increase the size rather than decrease.  The ring in these videos has a pronounced raised letters inside the shank of the ring, so  you can’t stand it on a triplet as you will damage the raised letters inside the ring.  The starting size is 16.15 mm and the customer needs it to be 18 mm. I am going to start by cutting the opposite side of those letters through the bottom of the shank or bottom of the ring. Make sure you cut it straight keeping it even, let the blade do the work.

Applying some heat makes the metal more pliable, I am going to use half round pliers and bend it out. Make sure what you do on one side you do on the opposite side as well otherwise it won’t be even. click here to see all 3 videos

The must know on how To Resize A Ring

If you have an ill-fitting ring, or eyeing a particular ring that is not available in the size you want, don’t worry. You can resize a ring. Now, while an expert jeweller may be able to help you get just the right fit, it would be wonderful if you can do so yourself. There are some people who have decided to pursue their interests in making jewelry and repair – and with good reason.

Why Learn About Making Jewelry

We all love nice things – and jewelry is one of them. It can be sad when we have a nice ring that we cannot wear since it does not fit though. This is especially the case with heirloom rings. However, with ring resizing, you will be able to wear them in no time.

Why Silver is a good metal to work in, is it ok to use scrap?

People ask me ‘Why is silver a good metal to work with?’.

Personally I love the look of silver it has a lighter colour than platinum and white gold it looks brilliant for fashionable pieces.

It’s one of the easiest to work with when you know what you are doing, bending it into the shape you want is just a dream and you don’t need a high fierce heat to get the solder to run Continue reading


Casting weight table wax to silver and so on…
Casting are normally 5% smaller than the master, it doesn’t normally make any difrance but you can do it in some cases ie; If you make a ring it will shrink one size so make your master one size bigger.

When pricing up, find out how much casting charge is, Metal Moulds and find out how much the moulds are for each size. Continue reading

How to make a bracelet


my style is big and chunky but this means is normally expensive so been looking into something more cost-effective. But I need to keep my style so people know it’s something I’ve made.

Cheap/Trendy jewellery wholesalers

I know a lot of people search ‘Google’ ‘The cheap Jewellery Wholesalers’. It’s not that hard for me as I work in Hatton Garden and is full of Jewellery Wholesalers. So I put myself in your shoes, search Google for cheap but quality materials, there are a lot of websites out there that are not very good. So it got me thinking; how do I know any of these websites are legitimate and true to their word? Then came to me.

What website does anyone use and trusts?

Well it’s eBay of course. Now eBay is not 100% safe and I say safe as in; you can get ripped off. But as long as you check the sale persons feedback, you’ll be fine you don’t have to go with 100% sale persons as Long as its in the high 90’s then I would say it’s pretty safe. But make sure you read the description carefully. I have been caught out before, nothing bad just not what I expected. I purchased some leather bracelets and rubber cord to add silver to make it look more modern and funky. Now this is a winning way to make money without spending a fortune.

The only limit you have is your imagination. If you have worries my advice is; Not to worry and just make it. Everyone makes mistakes and there will be times where you will think it’s going all wrong but in the end you will just make it work. Just believe in your making abilities. The key is to not worry and have fun and enjoy what you do.

Right now get out there and make a brilliant piece

Making your own Jewellery Ideas

Where to start?

Begin by picking from the big label’s that influence you, ie: Tiffany&Co, Boodles or De Beers. Do the research on what’s hot and what not for that season, always best to join a newsletter, that way you are always in the loop of what is up and coming. You will start to notice that every designer tends to be on the same level, you may see earrings with the influence of feathers! then before you know it another designer will come up with a similar idea..Nature!

Now find a piece that you like, this could be a ring? a bracelet? whatever it is feel inspired to make it better! alter it to your design! don’t be scared and think you can’t do this, like I said before anything is possible!

Pick a notebook that you can carry around with you when new ideas pop in your head! Sometimes hardbacks are good so it can protect the pages while in your bag or inside jacket, leaving your ideas nice and crisp!

If it helps, print a picture of your chosen piece and draw on it change or add bits to make it your own! Dont think you are copying cause your not, inspiration is around us and remember they had to be inspired too!

Now whats stopping you!

Jewellery Inspiration!

Everything around us has been designed by someone that has used their imagination to the fullest. From the New Liverpool Museum using a ‘Walnut Whip’ as the inspiration with its white spiral interior to the Harry Winton Sky Scraper Ring! Anything is possible if you put your creative mind to it!

If Jewellery is one of your passions combine it with another passion. What do you mean? You may ask. Well for instance I love Jewellery and Music! Funky house, Old School Jazz. Use your imagination and combine the two! If you get stuck, what I would normally do is type the name of my passion(into an amazing gadget the IPhone) into ‘Google Images’ and you will be amazed on what will come up.

 I always advise to carry a small notebook; you never know when you will get inspired! You could be travelling into work or having coffee at your favourite coffee shop- ‘ ill have a Black Americano please’. If you forget your notepad grab a napkin!

 If you have an idea but don’t think you have the skill’s to make it, don’t worry I’m here to help and guide you to your perfect Jewellery Piece.
