Great info!! Thanks!!99% of old clays that aren't Paulson or TRK, are Burt Co. There were only ever seven manufacturers that made clay chips, but you can boil that list down to 4 if you want to.
Burt Co/ASM/CPC
Paulson
TRK
Matsui
BCC
USPC
Hispania
You can condense that list to just Burt Co, Paulson, Matsui, and TRK; as BCC just used old Paulson equipment and methods, Hispania bought all of their equipment from Burt Co, and USPC sold all their equipment to Burt Co.
Nice pickup. I like the old hourglass mold, it has a smaller recess and a nicer feel compared to the current hourglass mold, which is in my bottom three molds for CPC.
Got any info about, or examples of, Matsui clays? I recall @BGinGA saying they weren't very successful..Matsui
There’s this thread:Got any info about, or examples of, Matsui clays? I recall @BGinGA saying they weren't very successful..
Thanks for that pointer!There’s this thread:

And I think there was a 200-chip set of Matsui clays somebody on here has, so if you find them you can ask some questions. I’m not 100% sure that they were really compression-molded, but I have no evidence that they were injection-molded, and have yet to feel any for myself, so I can’t be sure either way.
That may be true, but it’s surprisingly difficult to make inlays in clay chips. Matsui would have had to invest hundreds of thousands of dollars to get more than one edge spot and to have real inlays. I’ll email Roxana from Matsui and see if she has any more information, but I’d say it has the possibility to be a manufacturer. One of the main reasons I didn’t immediately dismiss them as injection-molded was because of the photos showing a bunch of clay chips that were baked in the oven, which seemed to show similarities between Matsui chips and some well-known compression molded clays.Thanks for that pointer!
I think we have to remove Matsui from the list of manufacturers of clay chips. Seems very clear to me that they're injection molded: they only offer one spot configuration and they only offer labels, not inlays. These are hallmarks of injection molding, and it's compression molding which gives the chips we call "clay" their fundamental character.
Matsui might call them clay, but outside of this forum "clay" is a completely meaningless term, used by everyone to describe every kind of chip.
To take an inlay the chip needs to be punched with the shape/size of it. That’s why CPC can’t just print whatever size inlay you want and stick it on the chip before pressing. Along with that, there is a special process that involves some sort of varnish, I believe, which you would only know about if you worked for a compression clay company before.So... made from thermosetting rather than thermoplastic materials, and compression molded... but for some reason, unable to take an inlay during the molding process, and unable to cut different insert patterns into the blanks.
Seems plausible, but it mostly just makes me wish I had more details about how Matsui made these.
Also it makes me want to get my hands on some!
The investment required for low temp/low pressure compression manufacturing is much smaller than a high temp/high pressure operation.it’s surprisingly difficult to make inlays in clay chips. Matsui would have had to invest hundreds of thousands of dollars to get more than one edge spot and to have real inlays.
Agreed. But then, for the same reason, it also seems odd that they would invest in compression-molded chips at all! They've got injection-mold equipment and infrastructure - quite sophisticated, given the quality of IM chips they produce - so all they'd need to invest in further is some new molds that replicate the "clay chip" appearance of debossed edge molds and colored inserts, and then just use the new IM molds on their existing IM presses.For a company that already has laminated adhesive label production capacity, it makes perfect sense to offer molded chips with a recess/label (plus hot stamps) vs trying to reinvent the wheel and attempt compression-molded inlays.
That is super interesting! I hadn't known that.To take an inlay the chip needs to be punched with the shape/size of it.
Some companies have been able to add inlays without needing to pre-punch the inlay shape, I suspect. The various vintage Paranoid chips have die-cut inlays in weird shapes; I suspect they didn't have matching punches to pre-punch a weird-shaped indentation in the surface. Likewise with the intricate die-cut metal inlays on some Burt Co chips, like the ones in this post.Edit: I’m not 100% sure if other companies like TRK and Paulson actually required inlay punches but again, as with many other parts of compression molding, very few people have the knowledge to back that up. I do know CPC requires them, though.
I'll reserve my opinion until I can hold some in my very own hands. Any volunteers?I'll assume after reading that 2005 chip review that you now agree that the Matsui M mold chips are/were indeed compression-molded clays.
I think the reason the intricate metal and paranoid designs didn't need a punch is that all of the chips that had those were solid. That means that having a large amount of clay displacement would not make the edge spots get wildly messed up. Inlays, on the other hand, are frequently put on chips with edge spots so they can't afford to have that much inlay displacement, or else the chips would all look like they were made by Dr. Ott.Some companies have been able to add inlays without needing to pre-punch the inlay shape, I suspect.

But! I wasn't there, I don't know, I could be wrong! Maybe any time they made a die to cut fancy shapes, they used that same die to fabricate punches so that the die-cut inlays would lie smoothly within the chip surface before pressing. I'd been assuming that all that was necessary was to plop the inlay underneath and on top of the blank semi-cured chip and let the pressure of the mold do the rest. Maybe that was a rash assumption.
Matsui actually has a video on their website that explains the process (at least in part).That may be true, but it’s surprisingly difficult to make inlays in clay chips.

The link was a different color, it made no sense, but I still clicked. I’m so disappointed but yet so proud.Matsui actually has a video on their website that explains the process (at least in part).
Matsui Clays
One way to confirm that the chips were injection molded would be to take several chips and closely compare their edge spots. Edge spots made by compression molding will have minor variations from chip to chip, so that every chip is unique. Edge spots made by injection molding will be the same from chip to chip with high precision, so that every chip is identical. You can see this difference by looking very closely at some Paulsons and then some china clays.
