Caveman Cups contacted me recently and asked if they could send me some products to test (along with a contribution in support of my advocacy work) and if I would then report the results on my blog and I said “sure!”.

As always, I explained that…

1.) I don’t/won’t do any sort of “paid endorsements”. Moreover, if I like a product, I may be inclined to say so in a blog post, but if I have any reservations, my opinion will not be subject to influence or censorship.  

2.) When a manufacture or distributor makes a contribution in support of my work when agreeing to test their product, if I find toxicants, I will, as a courtesy, report back and give them an opportunity to fix whatever their production issues might be that resulted in the “fail” (so-to-speak) — and to communicate with their customers, etc. — but regardless, I will ALSO report the results to my readers. [And of course in such an event, folks that take prompt and responsible action will likely fare better with my readers than those who do not!]

So while this could be viewed (in a sense) as a “sponsored” post, I want my readers to know that, as always, my results are science-based and replicable and, most important – an impartial, honest assessment of the product.

When tested with an XRF instrument, these Caveman Cups pint cups were negative for all of the toxicants that I generally look for and have a concern about: Lead, Mercury, Arsenic, Cadmium, and Antimony [which is to be expected, as non-complex all-stainless-steel items should normally be free of these toxicants]. Continue reading below for the full XRF test results.

These cups are certainly very solid, heavy and durable — notably more so than most of the other stainless cups and similar products that I have tested in the past; this is obviously a signature intention/selling point of the Caveman brand.

In light of the excellent test results, and the clean and sturdy construction of these cups, I personally think these would be a great Lead-free choice for any family!

Lastly, when I tested the cup I noticed the somewhat novel cream-colored logo on the bottom. Even with the tens of thousands of items I have tested, I had never seen an etched logo with a distinct color like that, so I asked the company about it — and here is what they shared with me:

“The color of a laser etching in stainless can vary from dark gray to faint creamy reddish. It depends on the laser settings, heat, depth, pattern, timing, as well as the composition of the steel alloy, etc. as to what the final color is. We like there to be a slight color difference between the etching and base metal, so it is easier to see/read the logo. We also want our products to be timeless and classy and look beautiful on a table with other dishware, so we keep it low-key and always put the logo out-of-sight on the bottom. We chose the laser etching process because it’s more eco-friendly than acid etching and we specifically avoid all types of paints, epoxies, coatings, wraps, chemicals, etc. We also designed our products without seam welds, spot welds or crimping along edges as these are also notorious for harboring contaminants.”

I have several more products from this company that I will be testing and sharing about, so stand by (I will also be giving them away as prizes on Facebook, so check in there too and make sure to follow my page!)… and in the meantime, based on the the company’s healthy and practical design approach — and what I have seen and tested, I think Caveman Cups genuinely “walk-the talk”, and would thus be an excellent choice for everyday use (as well as more rough-and-tumble use, like camping, sailing, etc.!)

When tested with an XRF instrument, the cups pictured here in this post had the following readings (all tests done for a minimum of 180-seconds/3-minutes, & results are replicable):

The readings [using the instrument’s installed optional “Metals” software module and testing mode] included an identification of the specific alloy as “Stainless Steel #304” — to learn more about Stainless in general, click this link: “What is Stainless Steel?”  The primary constituent metals found in food-grade stainless steel are Iron, Nickel* and Chromium (combined in different amounts with different additional ingredients in varying amounts to make the various stainless steel alloys.)

*While some people have concerns about Nickel allergies and leaching, I cannot personally speak to these these concerns (I have never experienced any issues with Nickel or Nickel-containing products with my family). My general advice around this subject is that (providing you start with Lead-free choices) it is a good idea to keep your dishware and cookware usage varied – with the thought that it is less likely that any one particular element (Nickel, Chromium, Iron) may become a concern on its own. What this means for my family is that we primarily use stainless steel, cast iron and glass in our kitchen (as well as bamboo and other untreated wood for some serving or short-term storage applications), and we naturally vary which items we use any given day.
