Description

Gerstley BorateGerstley Borate is a naturally occurring boron rich mineral used as a flux in ceramic glazes, particularly in low and mid fire applications. It helps lower the melting temperature, promoting smooth glaze flow and enhancing surface gloss. Due to its high boron content, it also improves glaze adhesion and contributes to the development of rich, variegated textures.

Gerstley Borate is a naturally occurring boron-rich mineral used as a flux in ceramic glazes, particularly in low and mid-fire applications. It helps lower the melting temperature, promoting smooth glaze flow and enhancing surface gloss. Due to its high boron content, it also improves glaze adhesion and contributes to the development of rich, variegated textures. Gerstley Borate is known for its ability to create stable, semi-matte to glossy finishes, but its natural variability and solubility can sometimes cause glaze inconsistencies. As a result, many potters and manufacturers substitute it with more consistent boron frits for greater reliability in glaze formulations.

Very good sunscreen, advice from a pale-skinned person
Size: 12 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50
I'm Scottish by descent, and so is my skin. This stuff works well, is pleasant, not greasy and seems to hang on despite kiteboarding, surfing, cycling, whatever. Pleasant smell, good dispenser.

Good product, the pump bottle could be better
Size: 12 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50, Size: 12 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50
This is a usual product for me, I like and trust it. It has little smell, spreads on easily and can be washed off without too much trouble. The pump is nice while it works but I take away one star because it leaves about 20% of the product in the bottom of the bottle when the "cone of depression" gets lower than the bottom of the tube that brings the product up. After the pump can no longer effectively pump the product up, I cut the top of the bottle off and dip the rest out with my fingers. I'm not sure what they can do to make it work better but it's inconvenient as it is.

Excellent protection for workouts and hot days! ☀️🏃‍♂️
Size: 8 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50
This sunscreen is fantastic for daily use and outdoor activities. The SPF 50 protection is highly effective; I’ve used it under intense sunlight and haven't gotten burned at all. What I love the most is that it actually resists sweat and doesn't run into your eyes when you are working out. It doesn't leave an overly greasy feel, and the 8oz size lasts a long time. It is a reliable product that is always in my bag. 100% recommended purchase!

Very helpful
Size: 8 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50
This sunscreen is a fantastic value, especially since I managed to grab it while it was on sale. It applies smoothly without feeling overly greasy and provides solid protection for outdoor activities. It is definitely worth picking up if you can find a good deal on it, as it does exactly what it is supposed to do. I will be keeping an eye out for another sale so I can stock up for the rest of the summer.
