About Glass & Cotton

Every recommendation here is checked against the manufacturer's published material composition and its third-party certifications, and both are cited on the page so you can check them yourself. Where a brand's safety claim rests only on its own marketing, the page says so in those words.

What it does not do is test products. There is no lab here and no test kitchen, and I do not claim to have cooked on, slept on or worn the things on this site. How we choose sets out the method in full, including that limitation.

No degree, no certification, no license, no professional title, and no years-of-experience figure. I am not a chemist, a toxicologist or a building biologist, and I have not been trained in any of those fields.

What I do is read specifications and standards carefully, write down what they say and do not say, and cite the source. That is a real skill and a useful service, and it is a different thing from expertise I do not have. A site that inflated it into credentials would be doing exactly what this site exists to push back against.

There are currently 102 research pages here. The kitchen came first and is the deepest section, because heat, acid and abrasion all happen there and they are what actually move a material into food.

From there the plan runs outward through the house in the order that contact time justifies: bedding and home, cleaning and laundry, beauty and grooming, baby and kids, pets and fitness. One swap at a time — which is also how I would recommend anyone actually do it, rather than replacing a house in a weekend.

Affiliate commissions, through Amazon. If you buy something after clicking a link here, the site may earn a commission at no cost to you. That is the only money this site makes.

It does not change what gets recommended. Where the cheaper option is the one that earns less, it still goes first, and no brand pays for placement or sees a page before publication. The full statement is in the affiliate disclosure, and the independence rules are in the editorial policy.

If something here is wrong, I want to know. Email contact@glassandcotton.com with the page and the correction, and a source if you have one. If the page is wrong I will change it and say that I changed it.

That is not a formality. The entire proposition of this site is that its claims are checkable, which is worth nothing unless I act when somebody checks one.
