SAFETY

June is National Safety month.

Hopefully it is not a surprise that we are an industry that should be tuned into our personal safety. Not only do we deal with lead, but we also deal with lots of dangerous chemicals.

FLUX

Flux is one of the worst we deal with. It contains acids, sometimes solvents and other chemicals. We heat it up and create fumes. If you are not careful, you will be breathing these fumes. Set yourself up with a fume trap or at the very least something that is blowing the fumes away from you.

Weller Fume Trap Smoke Absorber

It is a little tough to do as you don’t want to cool your solder prematurely. Every chemical has an SDS (Safety Data Sheet) that is readily available. If you are concerned about the flux you use, ask for the SDS or look it up online. You will have all (or more) the information you could possibly want.

SOLDER

Solder is made with lead (unless you are using lead-free). I don’t know anyone who wears gloves when soldering. People generally have the soldering iron in one hand and a strip of solder wire in the other. Lead is absorbed through your skin so that is the real health issue there. If you are not going to wear gloves, then wash your hands after use with heavy metal soap. Years ago, we had Safety Works in doing some safety testing for us. He told me to get the soap and have it at the sinks and then sell it and not be bashful about pushing it on people. They are touching lead and they need it! So, yes, we have it in our bathrooms and at our classroom sink and we sell it. So here it is. You need this so buy it and use it! Don’t eat where you solder. Just don’t. If you are making something that people are going to handle (jewelry, nightlight, boxes), use lead-free solder. We have gotten great feedback on this Amerway Tourmaline Lead Free Solder. It is the shiniest!

GLASS HANDLING

Stained glass people love to pick up a big sheet of glass and hold it over their head and look through it. DON’T DO THAT! If it breaks it is breaking into your open eyes! Don’t let glass slide down in your hands. That cut will need more than a band aid. In our retail store, we take care to push the glass into the display cubbies every day. We don’t put short sheets down into the record racks where people can skin their hands trying to get the pieces out. We put the taller glass to the back so people are not reaching over it. We are checking the scrap glass all the time as it is sharp and pointed. Wear glasses when cutting and grinding. Wear gloves for glass handling. Wear a dust mask when using glues and powders. This is supposed to be fun. Stay safe!

All credit for this blog entry goes to Bethlehem Burners. This is from their website. Helpful Tips from Bethlehem Tip # 1: Do not use force when cleaning your torch. Using extra force when cleaning your hypo tubes may cause internal damage to the torch. Such as scraping or breaking the hypo tubes which can lead to internal premixing. Only use gentle strokes and only use smooth wires. Cleaning wires with barbs or deep ridges on them will scrape and scratch the inside of the torch hypo tubes, weakening them over time. If you cannot clear an obstruction with the cleaning wires provided, please call us for assistance. (610) 838-7034 Tip # 2: Heat Tint Bethlehem Burners uses 303 stainless steel for the burner faceplates and torch barrels. Stainless steel develops a tint or coloring when the metal is exposed to heat and air. Heat tint found at the face and around the front of the torch barrel is to be expected and will darken with continued use. This discoloring is normal and purely cosmetic. Tip # 3: Removing Heat Tint Removing heat tint is not required maintenance for proper torch use. If the flame worker would like to remove the heat tint, simply rub a plastic dish-scrubbing pad (Scotch Brite) in a circular motion, until the heat tint has been removed. DO NOT USE STEEL WOOL. Steel wool will scratch the metal of the torch. Tip # 4: DO NOT SHOCK YOUR TORCH. Placing a hot torch face in cold water to “shock” trapped glass free from the torch will weaken the torches connection sites. Metal expands and contrasts when heated and cooled, therefore any connection site on the torch formed by fusing metals together, will become weakened if the metals have been heated and then cooled rapidly (shocked). Tip # 5: Do not use wires to remove glass Do not use the provided wires to remove glass. If glass becomes lodged inside the torch ports, please contact Bethlehem Apparatus for expert advice on how to remove the glass. (610) 838-7034 Tip # 6: Ask us about your torch! If you find yourself questioning what to do about your torch, give us a call and we will be glad to help! (610) 838-7034 TORCH CLEANING INSTRUCTIONS The working life of a Bethlehem torch is greatly enhanced when properly cleaned. Removal of carbon deposits on the face of the burner will prevent hot spots and deliver a clean particle free flame. Our new Stainless steel torches (Alpha, Bravo, Champion) have more oxygen ports in proportion to gas ports. This prevents carbon build-up; therefore these models do not require cleanings as often as our previous models. Step 1. Shutoff torch and allow cooling down for 10 minutes. Step 2. Gently brush the torch face in a back and forth and up and down motion for about 6 minutes. Step 3. Clean gas & oxygen ports with the two wires provided. Using the small wire for the smaller oxygen ports and the larger wire for the larger gas ports, located on the front face of the torch. The pentagon shaped center fire has 6 thin walled stainless steel hypo tubes. The hypo tubes deliver gas and the surrounding ports deliver the oxygen. NEVER USE COPPER, GLASS STRINGERS, TOOTH PICKS, OR ANY OBJECT THAT CAN BREAK AND CLOG THE PORT. Step 4. Turn on the torch with a lot of gas and oxygen and hit the underside of the torch with the supplied wooden dowel (never use a hard object to jar out any dust and carbon that may have entered the gas and or the oxygen ports during steps 1 and 2. Step 5. Shutoff torch and allow cooling for 10 minutes. Step 6. Brush torch face again, same as step 2. Step 7. Turn on torch with a lot of gas and oxygen and hit the underside of the torch to jar out any dust and carbon that may have entered the gas or oxygen ports during the brushing and wire cleaning cycle. Step 8. Shutoff torch, torch is now all clean and ready for your next days work.

SO MANY PLIERS! When customers are new to stained glass, it can be overwhelming figuring out which tools to buy. As if choosing a soldering iron wasn't complicated enough, something that seems as simple as pliers ought to be easy, right? Maybe not! There are several tools that are used for breaking glass along a score. We suggest beginners start with a combo breaker/grozer. It is like two pliers in one. You can use the pliers to break the glass on the score line. Position the edge of the plier parallel to the score line with the curved jaw on the bottom. Holding the glass on the other side of the score with your hand, snap up/pull the piece apart. (Use a pair of grozing pliers on each side to break narrow pieces.) Once you've cut a piece, small bits that stuck to the score can be "chewed" off with the tips of the pliers. Just nibble those little bits right off to reduce the amount of grinding in your future. Then we suggest a runner. The jaws of a runner are slightly curved to create a fulcrum. There is a line on the tip of plier that you'll lay over the score line. Some runners have an adjustable screw to control pressure; the screw should be on the top side of the pliers (screw points up so you don't screw up!) Squeeze gently to start; you'll feel the score "running" away from you along the cut. The rubber tips eventually get torn up by the sharp glass and it really does make a difference in the pliers' performance. Get reasonably priced replacements here. There are other variations of running pliers that run the gamut of cost and function. The Silberschnitt pictured on the right is a high-end plier designed to be very exact and can break up to 5mm of glass. They can help with inner curves and small glass strips. Some people really like a plain breaker. These pliers have a smooth jaw for snapping the glass apart. They often have a wider jaw than a grozer. What are your go-to tools for breaking glass along a score? Which tool did you wish you had as a beginner?

There is a lot to chat about when it comes to glue in glass fusing. Let’s start with these cute little owls with wonky eyes. They started out with the pupils glued to the white nugget eyes. Since the glue cooks off at about 450F, the eyes just slid off the nuggets and landed where they wanted during firing! Solution? Drill a bit of a hole and the little dots will stay put and you will have sweet little eyes like the one in the second picture (done by Liz Watts of Rocky Coast Treasures). There are many different glues that behave differently and have different uses. Let's take a look at a few! GlasTac Blue Gel This blue gel has a thick viscosity and minimizes slipping even when not dry. GlasTac Pink Use the pink glue on something already set in place. The pink glue is runny and if you squeeze a tiny drop next to the element it will wick under the glass. Aloe Vera This is good for when you don’t want it to “set up”. It keeps pieces stable, but you can keep moving them about. Best to use generics because the name brands have added ingredients that can cause trouble. Hair Spray When do you use hair spray on your hair? When you are done! Same with using it on glass. It is a top-down adhesive. You spray to keep something as you have it, especially little things like fine frit. Buy it cheap with a pump. HoneyDoo Glue A gel consistency with quick set times and a clean bond. It has a stiletto tip nozzle which allows precision. Great for glass fusing. Super New Glue Our favorite super glue here at Stained Glass Express, it is formulated to dry clear. It comes in a tiny bottle so you don't have to worry about it drying out before you get a chance to use it! SOME GLUING TIPS: Put glue close to the edge of the top piece so that it can dry quicker. Stuck to the wrong place? Hopefully you put the glue near the edge! Use a razor blade to carefully scrape at the glue. Superglue that is not specifically designed for fusing may not dry clear and can give off toxic fumes during firing. Here is some helpful info. How do I unstick my fingers? (This section reproduced from How Stuff Works) Let's say you're repairing some broken pottery and before you can say "Whoops," you've glued your index finger to your thumb! The recommended first aid treatment for this is:

1. Scrape off any excess glue. Don't use cloth or tissue -- a chemical reaction between the fabric and glue could potentially cause burns or smoke.
2. Soak the bonded fingers in a bath of warm, soapy water.
3. Don't try forcing the fingers apart, or you'll tear the skin.
4. After soaking, use dull, rounded utensil to carefully wedge the fingers apart.
5. If you see no immediate success with this, drop a little acetone (found in nail polish remover) on the area. Again, try wedging the digits apart.

At first, the thought of someone getting Super glue on his or her mouth seems outlandish. But let's face it a lot of us have a bad habit of using our teeth to wrench or twist off particularly stubborn caps. Say you do that with the top of the tube of glue and, presto, you've given an entirely new meaning to the phrase "zip it." In order to unzip those lips, your options on what to do are a little more limited:

• Since you're dealing with an area on the face, do not use acetone.
• Using a wide coffee cup or bowl, immerse your mouth in hot water.
• You will also want to dampen the bonded skin from the inside of your mouth as much as possible.
• Once you sense a loosening of the grip, use a dull, rounded utensil to wedge your mouth open. Be careful not to force it, or you will tear the skin.

Of course, glue is made for keeping things together; researchers have modified super glue to become less toxic, making it an ideal replacement for stitches (even veterinarians use it!) So if you've got yourself stuck and find the instructions above aren't working, we recommend you seek professional medical help! What's your favorite type of glue for fusing? Have you experienced any kiln disasters that eventually came down the type of glue that was used? Let us know in the comments below!

The biggest question we get about grinder bits is "how long will it last?" Tough one! Depends on how much you use it. A bit can be adjusted up and down, and carefully you can use lots of the surface. Once you get a bare spot, move the bit up or down. Normally your wear will be even all the way around the bit. Occasionally, you will get a bare spot. You can still use the space above and the bare spot. The next biggest question we get is, "how do I get my bit off the shaft?" It's stuck! What you do not want to do is bend your shaft so do this very carefully. We send someone to our classroom every week to take the bits off, rinse them, and put them back on. That keeps the gunk from building up between the bit and the shaft and behaving like it is cement. The only way to get it off is patience! That is a bit tough when you just want to use your grinder. Take some 3 in 1 penetrant, (or any of these chemicals designed to loosen metal), let it set and see if it comes loose. If not, do it again and again and again until it does. In this "there is a gadget for everything" world, there are now different grits. These grits include: XFine, Fine, Medium, and Coarse. The fines are great for when what you are grinding is chipping. Glass with a surface, like mirror or irid for example. In the old days, we saved our old worn regular bit for this. Coarse or speed bits are for when you have quite a lot of glass to grind off. When you get too close to where you want to be you will probably switch back to regular as the coarse is a coarse grind. There are also sizes to get you into smaller spaces: For these bits each manufactures look a bit different, but most are interchangeable. There are also some specialties bits---like a lamp bit. The ripple bit is so you can grind rippled glass and it is smoothed out for foiling. The radius is a combination of flat and a place to round the edges to get rid of a sharp edge. It is used mostly for mosaics. The lamp head allows a nice, angled grind so angled pieces will fit well together. The Quick Fit System has become popular with the new Techniglass Grinders and can be used on other grinders. When the grit wears off you can just buy a replacement sleeve and not the entire fixture.

I think I have not researched an issue and come up with less concise data ever. Here are some things I did find.

FUSING

The causes of concern when fusing are lead and cadmium. Cadmium when combined with sulfur forms Cadmium Sulfide and results in deep yellow color. If mixed with Selenium and Sulfur, it gives you bright red and orange. Adding Titanium produces yellowish-brown glass. https://www.bullseyeglass.com/is-bullseye-glass-food-safe.html At this link you can find the list of Bullseye glass that contain more than 1% lead and more than .5% of cadmium. They recommend this list be capped with clear. They also said that transparent glass leaches lead/cadmium at levels below FDA limits and less than opalescent lead/cadmium-bearing glass. So, you can decide not to cap transparent glass. I also found from Randy Wardell in his book "Everything Else", this: The official answer from the glass manufacturers is, all tested compatible glasses have been tested by the FDA for food bearing surfaces and were determined to be suitable. However, if you add other processes or compounds to the items, for example paint, stains, decals, glazes, etc. it is important to check that these items are also approved for food bearing surfaces.

• Glassline pens are lead free and food safe.
• Mika powder must be capped.
• Iridized glass needs to be capped. Bullseye irid is safe if full fused.
• By spraying a coating of Fuse Master Super Spray on top - food safe.

The bottom line seems to be, if you have any concerns top the piece with a sheet of clear when fusing.

FLAMEWORKING

Clear Boro (COE 33) is food safe. Think Pyrex. Boro colors with high metal content or fuming are not food safe. Boro is food safe if the colors with high metal contents and fuming are not the surface. The metals can cause issues in microwaves and sometimes older dishwashers that get really hot during the drying cycle. I was not able to find a list of Boro colors with high metal content. However, here is a little info on metal oxides. When glass color is made, the metal oxides are stable and "in solution," anytime you work with the glass, in any manner, you may be breaking open "the solution" and expose the metal oxides. Rods can contain: Iron Oxide, Chromium, Sulfur, Calcium, Manganese, Manganese Dioxide, Cobalt, Arsenic, Potash, copper Oxide, Nickel, Chromium, Tin Oxide, Cadmium, Titanium, Uranium, Didymium, Selenium, Copper, Gold & Silver.

TRADITIONAL STAINED GLASS

In traditional stained-glass work where you solder, there are also concerns. If the product is going to be near food or next to your skin, you should use lead free solder. Or, if you are doing something like a night light for a child's room, use lead free solder. Lead toxins can be absorbed through the skin.
