These days lampworkers use  either single fuel torches such as the Hot Head &#8211; which use propane or Mapp gas only, or dual fuel torches such as  the Minor Burner &#8211; which use both propane and oxygen.\u00a0 There are a lot of different dual fuel torches on the  market today.\u00a0 The combination of gas and oxygen\u00a0 produces a hotter  flame and therefore cuts down on the time it takes to make each bead.<\/p>\n<p style=\"text-align: left;\"><strong>Glass Rods<\/strong><\/p>\n<p style=\"text-align: left;\">Glass rods come in a range of colours and Coefficient of Expansion &#8211; COE for short.\u00a0 Glass expands when it gets hot and contracts when it cools, so the COE is the decider on what makes two different types of glass compatible or not.\u00a0 As an example to try to explain COE, I&#8217;ll use just three different types of glass.\u00a0 They are: Effetre &#8211; 104 COE, Bullseye &#8211; 90 COE, and Gaffer &#8211; 96 COE.\u00a0 As each of these glasses expand and contract at different rates, that means that if you mix two of these glasses together, the molecules within them are going to be moving at different rates and therefore not able to settle into a cohesive state together.\u00a0 There is always going to be stress between where the two glasses meet.\u00a0 It is best to only mix  glass that has the same COE, but there is an exception&#8230;\u00a0 You can place small amounts of another COE on the  outside of the bead.\u00a0 i.e. a bead made with 104 COE, Effetre for example, can have a small amount, ie 5% of the surface area covered with 96 COE frit or stringer work.\u00a0\u00a0 These beads should not be encased.\u00a0  If greater quantities of glass of different COEs are mixed together, the stress that forms between the area where these two glasses meet will cause the bead to crack or break apart after it has  cooled.\u00a0 It might not happen overnight, but it will happen at some stage &#8211; a couple of days, a couple of months, even a year down the track&#8230;<\/p>\n<p style=\"text-align: left;\"><strong>Bead Release<br \/>\n<\/strong><\/p>\n<p>Each bead is created on a stainless steel mandrel, which has been coated in bead  release.\u00a0 (I use 316L grade stainless steel Tig welding rods.)\u00a0 Bead release is a combination of powdered ingredients, such as Kaolin, Aluminum Hydrate and sometimes even graphite or clay, mixed with water to give a cream like consistency.\u00a0 The mandrels are dipped into the release and allowed to dry before use.\u00a0 Bead release is necessary to enable the finished bead to be  removed from the mandrel.<\/p>\n<p><strong>Lampworking Tools<\/strong><\/p>\n<p>Various tools can be used to  manipulate the glass while it is soft.\u00a0 Flattening, poking, rolling,  pushing and pulling&#8217;dragging are some of the techniques that can alter the shape of the  bead or the design on a bead.\u00a0 There are lots of tools on the market that are purpose made for  lampworkers.\u00a0 Graphite blocks, stainless steel or Tungsten picks or pokers, brass rollers etc.\u00a0 Virtually anything that is heat resistant can be used &#8211; the graphite, stainless steel and brass are the common metals used by most.<\/p>\n<p style=\"text-align: left;\"><strong>Making a Bead<\/strong><\/p>\n<p style=\"text-align: left;\">The glass rods are melted one at a time in the torch flame and wrapped around  the coated mandrel to form the bead.\u00a0 The mandrel must be constantly  rotated to keep the hot glass centered and evenly heated.\u00a0 Further  additions of other colours are applied to the base bead to make designs and  patterns.\u00a0 The tools are then used to manipulate the glass, ie, dots placed as flower petals can have the outside edges pulled with a metal pick to make them pointy.<\/p>\n<p><strong>Annealing<\/strong><\/p>\n<p style=\"text-align: left;\">When you are happy with your bead, you need to anneal it so that it stays strong.\u00a0 There are two ways to anneal beads.\u00a0 One way is to place the bead directly  from the flame into an already hot kiln.\u00a0 There the bead will &#8216;soak&#8217; at the  recommended temperature for the particular glass that you have used for a  recommended amount of time.\u00a0 After this time, the kiln will slowly ramp  down until it can be turned off and allowed to return to room temperature.\u00a0  Usually overnight.\u00a0 The bead needs to be around room temperature before it can be removed from  the kiln.<\/p>\n<p style=\"text-align: left;\">The other method is &#8220;batch annealing&#8221;.\u00a0 With this method, the finished bead  is rotated slowly higher and higher up through the flame until the inner and the  outer temperatures of the bead are equalised.\u00a0 This prevents the bead from  cracking instantly.\u00a0 The bead is then immediately placed into either a pot of  Vermiculite or between two sheets of Fibre Blanket.\u00a0 These beads  need to stay put until cold.\u00a0 Once cold, the bead\/s can then be placed into a  cold kiln and run through the recommended annealing cycle for the type of glass you have used.\u00a0 (Different COE&#8217;s have different recommended annealing temperatures.\u00a0 Again, a search online will bring up the different recommendations.)<\/p>\n<p style=\"text-align: left;\"><strong>Cleaning<\/strong><\/p>\n<p style=\"text-align: left;\">Once the beads have been annealed, they need to have the bead release cleaned  out of them.\u00a0 As bead release is originally made from powders, once it is dry, it goes back to being powdery.\u00a0 (If you have ever bought cheap lampwork beads from China or similar, you will notice that they still have this powdery residue in the holes.)\u00a0 This dry release is dusty, and therefore a danger to your lungs, so do not breathe it in.\u00a0 Place the beads in water and use a bead reamer, or a wire pipe cleaner to clean the release out.\u00a0 Don&#8217;t pour the water down your drain as it will eventually clog them up.\u00a0 I empty my water out onto a section of my garden.\u00a0\u00a0 Cleaning under water has a  twofold advantage.\u00a0 I use a diamond bit motorised bead reamer and using it under water ensures it does not wear out as quickly, and more  importantly, dust particles are prevented from becoming airborne.<\/p>\n<p style=\"text-align: left;\">Rince your cleaned beads in clean water and allow them to dry.\u00a0 Your beads are now ready to be turned into a wonderful piece  of jewellery.<\/p>\n<p><strong>Beadmaking Hints &amp; Tips<\/strong><\/p>\n<p>A dark background behind your flame will help you to be able to see the bead  clearly.<\/p>\n<p>Position your glass rods so that they cannot roll off the table and into your  lap.<\/p>\n<p>When you put  a rod down, always place it so that the hot end is not likely to be   picked up by mistake.\u00a0 Glass stays hot for longer than you think.<\/p>\n<p>Your torch must be secured firmly to your workbench.<\/p>\n<p>A chair with wheels will allow you to make a quick exit if you accidentally drop  a hot piece of glass or equipment in your lap.<\/p>\n<p>&nbsp;<\/p>\n<p>If you have made it all the way to here, you&#8217;re obviously serious about things, so well done.\u00a0 I hope this has been on some help to you.\u00a0 Please feel free to email me with any further questions you have, or to let me know if I have made an error anywhere&#8230;<\/p>\n<p>It&#8217;s a fun art form.\u00a0 Lots to learn and understand I know, but it&#8217;s worth it.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>There are lots of books on the market which will help you to learn how to make beads.\u00a0\u00a0 Here&#8217;s some of what you will find in them, plus some hints\/tips of my own.
