Why does my colored glass lotion bottle have clear mouth?

Have you ever noticed that your glass lotion or serum bottles are clear at the mouth even the body is in other colors?

Why can’t the manufacture make the whole piece same color?

And what are the differences between this kind of bottles and the totally colored ones?

Here are the answers.

The raw material of glass is the mixture of sand,soda ash and limestone which is transparent or translucent powder or granule. There are normally 2 ways to get the colorful glass:

Add colorful paints into the raw material;

Paint the shaped clear glass.

When the paint is added to the raw material, you get a entire colored bottle, and the color is like the gene of the bottle, it is natural “since birth”. While the later is painted on the surface of the clear glass, it is like a coat, you can take it on and off as you wish. That is why the factory does not paint the mouth of a glass bottle or jar, the paint can be scratched off while screwing the lid. It is risky because the paint may fall into the skin care or cosmetics product. You must not want the paint pollute the ingredients inside.

Now you probably think that no body will choose the painted glass package,right?

Actually painted glass has a big demanding because there is a huge customizable color range, meaning you can have many choices of the color. Meanwhile, there are different crafts can be made by painting, such as gradient color. In this respect, the natural color glass has very limited choices because the paint for raw material is less.
