Understanding Gram Sizes When Buying Mineral Makeup

Understanding Sizes and Amount When Buying Mineral Makeup
When you begin using mineral makeup one of the most confusing things is all the different sifter jar sizes and the corresponding amount of product that fits in them. If you are buying brand name, such as Bare Escentuals, the amount it what is on the factory made label. However, when buying other Private Label Brands, it can get more confusing. After weighing and selling my own minerals I decided to write this guide is to help you gain a better understanding of what your buying and what you are getting.
Jar Sizes and Corresponding Amounts
Please keep in mind that when you are buying mineral makeup the jar size DOES NOT mean the amount that will be in the jar, it simply refers to the jars volume. For example, a 5 gram jar does not contain 5 grams of minerals. Also, minerals vary in weight slightly due to the ingredients, so all weights are approximate.

5 gram jars with a sifter hold appx 1.5 - 2 grams of minerals
10 gram jars with a sifter hold appx 3 - 3.5grams of minerals
30 grams jars with a sifter hold appx 8 - 10 grams of minerals
Teaspoons and Grams

1/2 tsp is appx 1 gram
1/4th tsp is appc .5 grams
How Long Does This Last?

9 grams of foundation will last appx 6-12 months, even with daily use
1.5 - 3 grams of eye shadow, blush,or bronzerwill last appx 6-12 months
1/4th tsp of foundation will last about a month, 1/8th should last about 2 weeks
1/8th tsp of eye shadow, blush or bronzer should last about a month
I hope this guide helps you choose the right mineral cosmetic products. Happy Shopping!!
