Coffee preparation techniques besides espresso like pourover.

What are the visually distinguishing characteristics of a Chemex three-cup hand blown that identify it as such? How do you tell hand blown and machine made apart?

Search and ye shall find:

Is my vintage Chemex hand-blown? (Yes)

Thanks for the quick response. I need to be more specific: I'm asking about new, not vintage, and specifically about the 3-cup design, not the larger ones described in the linked thread. I saw that a few days ago and it isn't particually helpful.

I believe you can see the seam in the machine made ones where the two halves are assembled. It bisects the bump under the spout. There is also a small flare at the base. http://www.chemexcoffeemaker.com/ten-cu ... maker.html

Hand blown ones are thicker glass, but unless you have both next to each other, that info is useless.

This is a circa 1970's hand-blown 8-cupper:

SCRATCH THAT:

I just took a closer look at mine and there is indeed a "seam". What I was led to believe is obviously incorrect. My guess is the seam is formed by the mold that the glass is blown into.

Mine has no markings at all and the glass is very rippled. Very much like this one on eBay:

Seems this requires much sleuthing to figure out all the mfg changes over the years.

I wrote to Chemex to ask them about mine, which is hand-blown. The OP is asking about a smaller one and could find out how to recognize hand-blown recent ones by asking the folks at Chemex. It would be great to post what's learned here.

Okay, let see if I can do better this time.
Here are links to the '3-cup handblown' and the '3 cup classic'.

The most glaring difference is the price :-))))

But the only visual difference I see is that the base on the handblown looks to be wider ??

Based on those images, the rim at the top is different. Machine has an even outer rounded lip that protrudes outward from the line of the upper cone.

I have asked the good folks over at Chemex and will report what I learn. Thanks!
