9 best glass grinders

Glass grinders, often referred to as herb or spice mills, are kitchen utensils and gadgets used for grinding and crushing various herbs and spices. They are popular tools for enhancing the flavor and aroma of dishes by freshly grinding spices or herbs as needed. Here's what you should know about glass grinders and their relation to kitchen utensils and seasoning tools:

  1. Design: Glass grinders typically consist of a glass container or jar with a grinding mechanism at the top. The grinding mechanism can vary but often includes a metal or ceramic grinding element that can be adjusted to achieve the desired fineness of the grind.

  2. Materials: The use of glass in the design allows you to see the contents of the grinder, which is especially helpful when you want to identify different spices or check the level of remaining ingredients. The grinding mechanism is often made of high-quality materials like stainless steel or ceramic to ensure durability and prevent contamination of the ground spices.

  3. Versatility: Glass grinders can be used for a wide range of herbs and spices, including peppercorns, sea salt, dried herbs, spices like cinnamon or cloves, and even dried chili peppers. Some models are designed specifically for particular spices, while others are more versatile.

  4. Adjustable Grinding Levels: Many glass grinders come with adjustable settings that allow you to control the coarseness or fineness of the grind, depending on your recipe's requirements.

  5. Easy to Use: Glass grinders are user-friendly and easy to operate. Simply fill the container with the spice or herb you want to grind, adjust the grinding mechanism, and turn the top handle to grind the contents.

  6. Freshness: One of the main advantages of using a glass grinder is the ability to grind spices and herbs just before use. This helps preserve the freshness, flavor, and aroma of the ingredients, as ground spices tend to lose their potency over time.

  7. Cleaning and Maintenance: Glass grinders are relatively easy to clean. Many models are designed with removable grinding mechanisms, making it convenient to clean both the container and the grinder parts.

  8. Aesthetic Appeal: Glass grinders often have an elegant and sleek design, making them suitable for both practical use and tabletop presentation.They can be a stylish addition to your kitchen or dining table.

  9. Storage: Some glass grinders come with lids that allow you to store the ground spices or herbs directly in the container, keeping them fresh until your next use.

In summary, glass grinders are kitchen tools designed to grind and crush herbs and spices, enhancing the flavor of your culinary creations. Their transparent design, adjustable grinding levels, and ease of use make them a practical and stylish addition to your kitchen utensils and gadgets, particularly in the context of seasoning and spice preparation.

User questions & answers

Question: Does this come with 3/4 and 1/4 inch bits? One comment said only one bit was received. Also, does this company provide prompt service
Answer: Mine came with the two bits. I have not had to contact company
Question: this machine work with 220v
Answer: You need to buy the model for 220v. The description tells you the correct volts for the model I bought
Question: Does it come with the debri guard
Answer: I'm not fully sure which debris guard you are referring to...it comes with a very small splash guard )you can see it in the photo behind the head), but no tri-fold, large splash board. For a very limited time though, there is a FREE Molded Eye Shield and Glass Snapper that comes with this grinder. Stock is getting low on this free promo though. Regards, Rainbow Art Glass
Question: Does this have an on/off switch or just a plug in and out for power? Is it relatively easy to clean
Answer: There is an on/off switch. It is very easy to clean. We own two units for different grinder bit sizes.
Question: Is the Shield beyond the grinder wheel removable
Answer: Yes. there are 2 positions beyond the grinder wheel available for this shield . Or you can remove it completely if you need to grind large pieces of glass.
Question: Would this work sanding the edges of reclaimed wine bottle edges after cutting
Answer: I bought this as a gift for my daughter who does stained glass. Here's what she said about using it to smooth the edges of cut glass bottles... "I wouldn't see why not. I've not tried it but would experiment with varying bit grits to find one strong enough to smooth but gentle enough not to chip the glass.'Hope that helps.
Question: So i take it the grinder comes with one bit, correct
Answer: It comes with one medium grit bit. Easy to change and the other bits are readily available.
Question: I'm sorry to sound silly, but exactly where does the sponge go?? I've never used a machine like this, and the included instructions are terrible
Answer: It goes behind the bit, and extending down into the water reservoir below. It wicks up the water from the water reservoir and carries it against the bit as you grind, so it needs to touch both of them. The glass sludge builds up against the sponge as you work, so you will need to periodically remove the sponge, rinse it out, and then re-insert it.

User questions & answers

Question: what are the overall dimensions
Answer: About 12" wide X 10" deep and 10" high.
Question: How do you install the 1/4" bit? Does it thread into the shaft or sit on top
Answer: The Gryphon Convertible Grinder does not have a threaded shaft. To use a 1/4in bit with this grinder, you need to use a bit that will slide over the top of the shaft. The Twofer 1/4in Bit will work well. You can search Amazon for "Twofer Grinder Bit" and you should find this item. = Scott = Sunshine Glassworks Ltd, Buffalo, NY 14227
Question: How much glass dust goes into the air during use? which model catches the most glass dust with the water: convertible, gryphette, or studio? thanks
Answer: Hi Ashley, I’ve got the studio; it does great, not much dust at all, the water sponge keeps it way down in my opinion. I put cardboard around it when I work, that catches the moistened dust.
Question: Does this work like a wet saw with a water reservoir to keep the glass cool and lubricated
Answer: I use a small water spray bottle with it to keep the diamond head wet. There is a water resevoir for the spent water but it doesn't recycle nor would you want it to. Great product at a great value!!!!!

User questions & answers

Question: Can you get a 1/8" or 1/16" grinding bit
Answer: The smallest grinder bit we offer is the 1/8" diamond drill bit for use with the grinding/drilling bit adapter
Question: can this machine remove words forming part of a bottle and does it come together with a smoother
Answer: Yes, the included grinder bit should be able to grind down and remove imperfections in glass bottles. While this grinder doesn't come with a smoother grinder bit, there are some available on Inland Craft's website.
Question: can this grinder use a 1" diameter grinding bit
Answer: Yes, it comes with a 1" diameter grinding bit
Question: will this grinder be able to shape porcelain dish parts without being ruined
Answer: Porcelain is a 7 on the Mohs scale. Glass ranges from 4-7. We expect it to work however, due to porcelain generally being a harder material, the grinder bits may wear slightly faster than when used to grind glass.

User questions & answers

Question: Is it true there is no “on/off” switch on this grinder
Answer: There is an on/off switch on the grinder. If you look closely at the picture, you can see it mid way down on the right side.
Question: Where is this made
Answer: All of our Inland Craft glass grinders are made in the USA
Question: How is the glass supported while using the small bit? Is there another support, does it mount down low, or is it just in the air
Answer: When the grinding bits are stacked as shown in the picture, there is not another support for the glass for the 1/4" bit. There is however, an Inland Craft accessory available to provide extra support. It's called the SecondStory work surface and is not included with this glass grinder machine.

User questions & answers

Question: will it do small sizes like watch crystals
Answer: I haven’t done watch crystals, but do grind small pieces of stained glass. Smallest I’ve done is probably inch x 1/2 inch. It works fine on big & small pieces. Just have to be careful holding small pieces.
Question: I’m finding that the edges of the glass with 3/4 bit that comes with the unit are a little rough. Could it be my technique or do I need a finer bit
Answer: In order to have a smooth edge, you need to ensure that you have the appropriate amount of coolant and water in your grinder. You should also apply even pressure when grinding. If it is a soft glass do not apply to much pressure, let the grinder do the work.
Question: Does this come with the eye shield? If not, how much is the eye shield
Answer: Yes, the eye shield was included.
Question: will these work on the gas star grinder
Answer: This is the Super Star II Glass Grinder, made by Glastar Corporation.
Question: Does this grinder use common grinder heads or are they proprietary
Answer: We have found that the Diamond Tech brand grinder bits do fit best on this grinder. Although the motor shaft is listed as 5/16", which is the most common size, we have frequently had difficulty getting TWOFERS brand grinder bits to fit onto these machines. We often succeed in getting the TWOFERS to fit after "polishing" the motor shaft with a strip of wet sandpaper (emery cloth) and/or "chasing" the hole in the grinder bit with a 5/16" diameter drill bit.
