Do you ever wonder if all glass bottles can be recycled?

Glass bottle FAQ’s

Did you know that glass is made from natural materials like sand and minerals? Once it's made, it takes over a million years to decompose, which means the first-ever glass created is still around! 

So, what can we do with an object that lasts forever? We can recycle it! All types of glass bottles can be recycled and reused, sparing the environment from waste. Best of all, for every ton of glass that is recycled, a corresponding ton of natural resources is saved. Make a difference - recycle your glass bottles!

Have you ever wondered why you can't fill a glass jar or bottle to the brim?

If you're wondering why there's always a gap at the top of your drink bottle, it's for a good reason. As the temperature changes over time, the liquid inside the bottle can expand. To accommodate this, every liquid has a specific filling method in relation to the headspace. 

For alcoholic drinks, you should aim for a headspace of about 4-5% of the total volume of the contents. In contrast, something like maple syrup requires a 7% headspace. 

So next time you fill up your bottle, keep in mind that leaving a little room at the top is crucial to preventing spills and leaks.

Have you ever wondered how the colour of glass is altered? 

Glass bottle FAQ’s

Beer bottles are brown, while vodka bottles are White - Glass colour can be changed using various methods. One way is by adding colourants to the glass, but this can be problematic for bottle manufacturers as it requires them to clean the entire furnace to prevent colour contamination in future production.

An alternative approach is to use feeders to introduce colour flakes into one section of the production process, resulting in coloured bottles. This process is more efficient as it only affects a small section of the furnace, making cleaning much easier.
