Description

ColemaniteColemanite is a natural source of boron commonly used as a flux to lower the melting point of glazes and clay bodies. It enhances glaze fluidity, promoting smooth, glossy surfaces while improving adhesion and durability. As a boron rich material, colemanite helps develop bright, well melted glazes at mid range and high fire temperatures. However, due to its tendency to release gases during firing, it is often replaced by more refined boron compounds

Colemanite is a natural source of boron commonly used as a flux to lower the melting point of glazes and clay bodies. It enhances glaze fluidity, promoting smooth, glossy surfaces while improving adhesion and durability. As a boron-rich material, colemanite helps develop bright, well-melted glazes at mid-range and high-fire temperatures. However, due to its tendency to release gases during firing, it is often replaced by more refined boron compounds such as frits to ensure stability and reduce defects such as pinholing or bubbling.

Excellent mineral face sunscreen with minimal weight cast.
I’m glad I tried this. I am enjoying this mineral face sunscreen. It leaves a minimal white cast as long as you gently dab it on, blend it out, and don’t add too much. It wears very nicely under foundation, cream makeup, and powders foundations. Very nice! It acts like a gripping primer for make up. There’s a few other mineral face sunscreens that I’ve tried and liked to, but this one is my favorite so far.

Lovely Moisturizer
My 14 year old needed something for her sensitive, fair skin and this purchase was perfect. She says it is light and doesn't feel like she's wearing anything on her face. The bottle is easy to use and aesthetically pleasing on her bathroom counter.

Overpriced and Underwhelming
I had high hopes for this sunscreen, but it was a major letdown. The texture is oddly thick yet doesn’t hydrate well, leaving my skin feeling dry and tight. It also pills terribly under makeup, making it useless for daily wear. Despite being labeled as oil-free, it somehow made my skin look greasy within a few hours. Plus, the strong herbal scent is overwhelming and lingers way too long. The worst part? The tiny 1.1 oz size for the price—it’s ridiculous! You barely get any product, and with daily use, it runs out insanely fast. Definitely not worth the hype or the money.

No white cast and no irritation
Great choice for my sensitive skin. Goes on smooth and absorbs quickly with no apparent cast. Did NOT cause oiliness or breakouts on my sensitive, acne-prone skin. No irritation after wearing all day. BONUS that it's HSA approved.
