Special Honors

D&L Art Supply TNG TG In addition to being one of the best-looking options on the market, this model offers an accessory tray with cutouts for easy organization and a larger eye shield than you'll find on much of the competition. Its top speed is also an impressive 4,500 RPM, and it's made in the United States. dlartglass.com

Ameritool Universal Heavy Duty If you're looking for a particularly strong flattop machine, this may be your best bet. It boasts a 1/4-horsepower direct drive motor, and comes with five ready-to-use discs as well as four backing plates for creating custom grinding surfaces. It's a bit on the heavy side, however, so it isn't the most portable choice, and it's quite expensive. kilnfrog.com

Editor's Notes

September 02, 2019:

Taking a closer look at this ranking, we wanted to make sure that glass artists and industrialists were being shown the best tools for the category, which is the primary reason we ultimately decided to do away with the Sickle Stone file previously at number four. Is it a great file? Sure. Does it belong on a list devoted to grinders? Probably not. Even the highly lauded wet belt sander by Covington was considered for removal, as an argument could be made that its very name belies a sanding purpose over a grinding one. In that case, we considered the fact that users can achieve similar grinding effects with it as they could some of the more compact grinders on our list, and that it ultimately came down to a given user's skill and needs. The very low ceiling offered by the Sickle Stone didn't allow for this level of consideration.

Interestingly, we only ended up with a single flat lap grinder on our primary list, but it is one of the most highly regarded in the Hi-Tech Diamond eight-inch. We found another flat option from Ameritool that made its way onto our special honors list for good measure, and that one comes with an excellent accessory kit, including a quartet of sanding discs (as well as a white polish pad) and an additional four backing plates.

Grinding It Out: A Brief History Of Glass Making

In an attempt to recreate the treasured gemstones of the day, ancient Romans and Egyptians produced colored glass.

Before we knew how to make glass on our own, Stone Age humans made efficacious use of materials like obsidian, a naturally occurring volcanic glass. Still in use today, these handy little fragments are hard, yet brittle, so they can be easily fractured and manipulated into effective cutting tools and weapons, and when polished they make an excellent mirror or decoration. This inherent versatility made the material extremely valuable to ancient people, and because of this it was extensively traded.

Although no one knows for sure, archeologists have found evidence that the first manmade glass may have occurred in Egypt and Mesopotamia around 3500 B.C.E. Most likely, this ancient glass was a happy accident, possibly the by-product of a separate metallurgical procedure. Some experts suspect the process evolved from the creation of faience, a pre-glass material with a vitreous coating that occasionally consisted of powdered quartz melted at extremely high temperatures.

In an attempt to recreate the treasured gemstones of the day, ancient Romans and Egyptians produced colored glass. Artisans simply added metallic salts during the manufacturing process to produce the desired results. As the procedure evolved, this type of glass flourished alongside the spread of Christianity throughout Europe in the 4th and 5th centuries, popping up in the windows of cathedrals and churches. Creating a stained glass window took enormous skill, not to mention a hefty dose of engineering know-how in order to form the intricate designs. A worker needed to sand and file a piece ever so precisely so that it would fit within a complicated framework. Considering the monumental size of some of these projects, creating a complex biblical scene or other elaborate work of art was no mean feat.

Which Glass Grinder Is Right For You?

Whether you’re a DIY enthusiast making a wind chime for your home or a professional glass artist, you’ll need the proper tools to complete the task at hand. If you simply want to personalize an already formed item, such as a mug, plate, or bowl, then an engraving kit is a must. These kits provide the fine writing tools you’ll require to etch glass with delicate details and designs, like a name or a picture.

If you simply want to personalize an already formed item, such as a mug, plate, or bowl, then an engraving kit is a must.

For small jobs that require a light smoothing, like rounding out the edges of a microscope slide, sometimes nothing more than a sheet of wet and dry sandpaper or a handy nail file with the right grit can do the trick — so long as you don’t mind dousing the latter in water. Better still, a sickle stone file is an excellent choice for rough edges and sharp corners, especially if you frequently have to address small imperfections. For the hobbyist who requires a deft sanding for, say, turning reclaimed wine bottles into safe drinking glasses, a rotary tool will make quick work of the task. It's always a great idea to have one of these versatile devices around, as they can clean, polish, and sand a variety of materials.

If you need to address a broad surface area, a wet belt sander is the way to go. Especially ideal for those who work with large panes, these machines offer superb accuracy. They stay moist via hidden water reservoirs with standard sponges inside, and they often have tilting platforms that make beveling edges a breeze. You can easily change the belt to accommodate any job. For example, an extra coarse belt will swiftly eliminate a jagged edge, and a super fine one can leave a piece perfectly polished with a satin finish.

If you’re serious about your craft and want to take your projects to the next level, then it’s worthwhile to consider investing in a quality electric machine with a powerful motor. Not only do these devices provide an ample surface on which to work, but many models have ingenious methods to keep your glass wet. Whether it's a simple sponge holder or a ventilation system, these setups are perfect for keeping your piece cool despite the high heat that comes from intense friction. This moisture also serves to trap harmful dust particles, which stops you from breathing them into your lungs. Certain machines come with handy accessory drawers ideal for storing extra bits and pieces, plus you'll have both hands at your disposal while you work, giving you greater precision and authority over the way your piece comes out.

On The Safe Side

Handling and manipulating glass is a tricky business that doesn’t come without risks. While grinding glass seems like a simple task, it’s easy to injure yourself if you don’t take the proper precautions. Start with protecting your own person. Safety goggles are a necessary preventative measure for any hobbyist, as once a stray waste piece flies into your eyes, it can be incredibly difficult and painful to remove it.

It not only protects your torso from unwanted sparks but keeps your clothes clean and out of the way, so you needn’t worry about a stray thread catching on your machine.

You should always wear gloves to protect your fingers from nicks and cuts and stop them from getting pinched in your machine. It’s good to be aware of where your hands are at all times, and be sure to never let them get too close to a belt grinder or wheel, lest you’re willing to part with your skin. Furthermore, you’ll need to ensure that you roll your shirtsleeves up, and if you have long hair, keep it tied back and away from your face. You don’t want to obscure your vision or risk snagging your precious tresses.

Another helpful accessory is a quality leather apron. An apron provides a necessary barrier between your garments and your grinding equipment. It not only protects your torso from unwanted sparks but keeps your clothes clean and out of the way, so you needn’t worry about a stray thread catching on your machine.

In general, it’s always an excellent idea to keep a first aid kit close by in the event of an injury, be it minor or major. At the very least, you should stock it with plenty of bandages, antibiotic ointment, eye wash, and sterile gauze. These simple measures can make all the difference in ensuring your comfort and wellbeing while you work on your masterpiece.
