A great blender. I am 82 years of age and in 1963 my mother gave me a gift of the Osterizer, same as pictured in this article. I made mostly smoothie breakfast drinks. My small “Mason” jar is made of quality heavy plastic and I used it for grinding my coffee beans among other uses; a few times I ground dry fenugreek seeds for making a poultice for wounds. I still have my Oster which I cherish and is still as good as new.
If you can find any way to use a wide mouth jar please test it and post. Oster and others make blend and go containers, but I have been unable to find any safe, practical way to put a wide mouth jar on a blender of any brand. Would love to have an attachment and hope someone will craft one.
Be careful… Oster used to promote this idea but stopped after law suits.
The actual blender beaker is made of tempered glass. Canning jars are not. A canning jar can have a crack. You try this with a cracked jar, especially with hot liquids, and cablooey!
Despite this caveat, I personally DO use canning jars with my very old Oster blender.
Hi Christopher, I called the Ball canning jar company hotline and learned the following. Canning jars are made with “annealed” glass, which is a process similar to tempering in that it makes the glass much stronger and able to withstand changes in temperature, than plain glass. It is not as strong as true tempered glass, which is the process that they use to make plate glass windows and automobile windows. With tempered glass the glass will break into a thousand small pieces when broken. Annealed glass will break into large shards.
I guess I’m reviving this thread! I’m looking for a blender on eBay, which will work with wide mouth canning jars. It looks like yours does. Would you mind confirming that and if so, telling me what model Osterizer you have? The model number should be on the bottom. I prefer an older blender because I think they were made to last, unlike those made more recently. Thank you!
Hi Laurie, this is an old post and I don’t have access to that blender anymore. But I do recall that the Osterizer worked with a small mouth, not a large mouth jar. I tried this technique with a KitchenAid blender and it worked with a wide mouth jar. You might have to just take a jar into a store that sells blenders and try the jars out on a display blender.
Hi Elise. Do you mean, in your comment to Laurie, that some blenders (like Oster) will accept a regular size mason jar only and some blendrs (like Hamilton) will accept wide mouth jars only? Is there any way to fit either one to a blender? I read about a gaget called Jinder Blender that would fit on a wide mouth for blender use. It was in early stages of manufacturing a few years ago but I cannot find the final product. Any info would be helpful. Thanks.
Hi Cubo, yes, some blenders will accept regular size mason jars, some will accept wide mouth. I don’t know about any product that would adapt one to another.
Excuse me…I meant Kitchen Aid – not Hamilton.
I see that this is good for dry goods but what about to make smoothies. Are there any pressure issues with wet goods?
I don’t think so, but I don’t recommend doing this with wet goods as it could get very messy.
This Youtube shows someone using this method with widemouth (+an adaptor) to blend up some hot potato soup. Maybe wide mouth works best for hot foods/liquids because there is more space at entrance???? https://youtu.be/0d-s98bKluw
One other thought I had — it’s possible that some of these incidents where the jars or containers seem to immediately come loose could be the result of a quick cross-threading. You stop twisting because you feel resistance, but there’s really no security to the attachment at all.
Every time I put it together, I plan to take it slow and make certain I’m not cross threading the assembly.
This is in response to Lynn on April 12, 2011 11:05 AM.
I checked my Oster setup with respect to the counterclockwise question. I can see which way the blade is going from the shape of the edges. It does go counterclockwise.
The jar or pitcher receives the blade assembly while you are holding it upside down, and you screw that on clockwise. However, when you turn the container upright, the direction of tightening becomes counterclockwise. The counterclockwise spinning is designed to tighten the screwed on assembly, not loosen it.
Lynn, I’m so sorry for your accident. That sounds really terrifying. I think it’s good to share that we all need to treat these machines with respect, because it’s always possible for something to go wrong.
Elise, thanks for this post! Awesome work!
I just went to Walmart to buy a cheap 24.00 Oster blender 14 speed. I tested the Ball small mouth jars with it and it worked so I bought pint sized ones. This is the best thing ever. I’m going to buy different sized Kerr Ball canning jars with the small mouth lid for my baby food.
I would be very careful about using this tip. The blender container is made to contain the pressure and vibration created by the blender; mason jars aren’t. And the cheaper, or thinner the jar, the more easily it will break. If the mason jar broke, you could have glass fragments coming out in a 360 degree arc. Is it really worth it? Funnels for filling mason jars are a couple of bucks. If you really want to do this, buy a jar made by the blender manufacturer; don’t just stick some mayonnaise jar made by the lowest bidder, thinned out as much as possible to save on shipping weight.
If you don’t want to believe me, at least send the kids out of the room before you try it.
Hi Steve – you should know that 1) mason jars are made with extra strong glass, to handle the heat and pressure that comes from home canning, and 2) using a mason jar this way with a blender was normal years ago. The blenders even came boxed with a mason jar and a booklet of instructions of how to use the mason jar with the blender. ~Elise
Placing a towel ove the jar while blending might be a good idea.
hmm, I’m having a hard time finding a reason why using a Mason jar as opposed to a blender would be any different, or any more beneficial, other than the fact that stuff like peanut butter would stick to the blender, whereas with the Mason jar, no transfer is needed.
Is that it? What would be so different about chopping nuts using a Mason jar?
I’m just curious, because I don’t really cook, or prepare food at all. However, this just looks a little gimmicky to me. Is there a big difference, and if so, what is it?
Sometimes getting things out of a blender can be tricky. This is just an easy way to chop or blend something, and then have it already in the container you intend to use to store the item. Also, sometimes it’s actually easier to use the mason jar for chopping things like nuts. Probably because in the mason jar, the nuts have a smaller place in which to fly around, and therefore you will likely end up with fewer big, un-chopped nut pieces. ~Elise
I love your out of the box thinking. And the mason jar idea actually solves a couple of my kitchen problems. Thank you.
What an amazingly clever idea! This article supposes that most modern blenders use the same-sized mouth as the ones from 40 years ago though, correct? Any idea if blenders are still made with a mouth roughly the same size? Also, seems like it could be messy when the time comes to flip the unit over and remove the mason jar (with blended, pureed, and whipped contents within!).
But I love the creative concept, and if I ever lose my glass food processor unit, I now know what I will try before buying a new one! Bookmarked for sure! :D
Last year on April 8, I was using my Oster blender and a pint canning jar to make natural peanut butter smoother. Before I could hold the jar down after turning the blender on, the jar came unscrewed and the blade became air born chopping three fingers on my right hand. After emergency surgery and months of therapy, I can see that I have permanent damage. Please DO NOT use jars on a blender that operates in a counterclockwise direction. I have used jars on blenders since the 70’s and this was the first time I had this happen. I do have to say when I used the Oster container, I also noticed a leakage when blending liquids but I did not realize the direction the blade was turning causing it to leak.
My wife was making us smoothies in her old blender with a glass container. She has done this many times in the past; but this time, much to our surprise. the glass jar broke and smoothie and glass went all over the kitchen. Luckily no one was hurt;but it took 3 hours to clean up the mess because it went everywhere!! Made me very leery of glass containers on a blender. It was the original blender container that came with the machine.
Thank you!! This is yet another example of commonplace ideas which have been lost over the generations. I relish them. Simple and thrifty solutions, and usually very good ideas for clean and non-toxic living…another thing that has been lost by the masses. I am going to use this as a solution for making babyfood out of my own homecooked organic meats and produce. yay!
Thanks. I had completely forgotten about this trick. I even have nice jars with handles & lids that I bought for this purpose but they were tucked away in a cupboard. You saved me from buying a new grinder. Thanks!
Elise, it’s coming up on the 5 year anniversary of your enlightening post, and you’re still changing people’s lives after all these years! I’m high-5ing you in the ether for your most brilliant tip that thrills me to no end! I now grind my flax seeds, oats, walnuts and dried fruits for granola in Mason jars and mugs with great ease and joy… THANK YOU!!!
This is so fantastic! I’ve been coveting the ease of use of the magic bullet and its ability to make smoothies to go, but didnt like the plastic cups. An internet search came up with zilch for a glass jar made by the manufacturers.
Thank you for posting this!
I’ve tried my jars of pasta sauce (says mason on the side) and voila!! They fit!
Yay! One less single use appliance in the kitchen!
I have been struggling for a few years now, with the problem of being unable to blend small quantities of Indian chutney with a blender. (I usually cook for one person.) I was very happy to see your tip. My Mason jars fit perfectly in the blender. My chutney still didn’t blend evenly but a big step forward though. Thanks.
Great advice! Does anyone know what type of Mason or other jar will fit a Wave Logic blender? They have an odd base, regular Mason jars don’t seem to fit. A jar will make it easier to blend small quantities. Thanks!
