What is a demijohn and what makes it special for lamps?

Demijohn with liquid inside

An demijohn It is a voluminous container, traditionally made of blown glass but also made of fired clay, characterized by its rounded body and wide base, which tapers into a long, cylindrical neck. Originally, demijohns were used to store and transport liquids such as wine, oil, or preserves. However, with the passage of time and the arrival of new industrial containers, this type of bottle has been converted into a decorative element of great value and versatility.

  • Unique visual appeal: The thick, green, transparent, or blue-tinted glass, with bubbles and small imperfections, gives the lamp personality.
  • Decorative styles: It fits perfectly in rustic, bohemian, Nordic, industrial and eclectic environments.
  • Great customization capacity: You can paint it, decorate the outside with rope, add LED lights, plants, or materials like stones, corks, and sand.
  • Ecological element: By reusing a demijohn, you contribute to recycling and sustainable decoration.

The rise of demijohns in home decor has made originals coveted collector's items. Finding authentic ones with a history can be difficult, but they still appear in antique shops, flea markets, vintage stores, or even through online sales between individuals. If you can't find an old model, large home decor stores often offer reproductions in different sizes, finishes, and colors, designed for decorative use and DIY projects like the lamp.

Where and how to get a suitable demijohn

The first step in creating your own lamp is to choose the demijohn. Keep these in mind tips:

  • Material and quality: Look for demijohns made of thick glass, free of cracks or breaks. If there are imperfections or bubbles, all the better! That will give them a vintage charm.
  • Size: Demijohns come in sizes from 5 liters to over 30 liters. Consider the space where you'll be placing the lamp to choose the most suitable one.
  • Opening: The neck must be in good condition. It doesn't matter if you have an original stopper: you can use a universal cork, rubber, or even create a custom one.
  • Color: Green and transparent shades are the favorites, but you can look for blue or amber tones for more sophisticated environments.

If you prefer to buy a new one, go to home decor stores, online portals, or even specialized department stores. If you want an authentic piece, your best option is to scour flea markets, antique shops, or inquire at wineries, as they sometimes part with old containers.
