Safety First, high quality borosilicate glass, everytime!


Why you should always make sure your glass pipes, glass bongs and bubblers, or your dab rigs and oil burners are manufactured from borosilicate glass.

The first and only reason is safety and lessening the risk of serious, life-changing injuries. First, we need to not necessarily understand physics; but we do have to appreciate some physics. Have you ever wondered how a thermometer works? It is because when things get hotter, they expand or get bigger and when they get colder they contract or become smaller. So, when it’s a warm day the liquid in the thermometer expands and travels up the tube and on a cold day, the liquid contracts and drops down the thermometer. It’s not just liquids in a tube that do this, it is everything to a smaller or larger degree. This degree of how much something expands or contracts is given a number or coefficient and the lower this number the less a thing expands or contracts when heated or cooled. The higher the number, the more a thing expands or contracts with heat or cold. The chemicals and materials used to make borosilicate glass when combined, create a material with a very low expansion number. This means that when it is subjected to extremes of heat and cold it does not expand or contract violently like when you put boiling water into a glass straight from the freezer and it shatters into hundreds of pieces. This is because normal glass can only withstand a change of temperature of around 40 degrees Celsius. Whereas borosilicate glass can withstand a temperature swing of 165 degrees Celsius. It can also hold its shape in heated environments up to around 500 degrees Celsius. This is why glass cookware is normally made from borosilicate glass, you might have heard of it as PyrexTM which is a trademark name for borosilicate glass.

So, before you go using any old bottle or piece of glassware and think of turning it into a homemade or custom glass bong. Think about it. Think am I going to heat this glass with a high-temperature heat source like a jet flame lighter? Could that glass potentially get too hot too quickly and shatter? Is that glass close to my face and eyes? Is it worth the risk of losing my sight or the sight of someone else who is vaping from a homemade glass bubbler you made and who doesn’t know the dangers?

Just because it’s borosilicate glass, It doesn't mean it's indestructible, it does break if dropped and can crack and become weaker when you apply heat to glass. Always take care when using heat on any type of glass.


Other things to look out for to prevent accidents or injuries are:
  • ·    Check your glassware for defects or cracks. If it is damaged don’t use it, it is much more likely to break.
  • ·    If you do break some glass, don’t use your bare hands to clear it up, wear gloves and use a dustpan and brush before vacuuming the area.


In the event of an accident have a first aid kit to hand and seek appropriate medical attention


Always take care and keep safe. A cut or burn may heal well and may not even scar, however, your sight is a different thing

Windproof lighters | Jet lighters vs USB rechargeable lighters

No blow outs

Windproof lighters come in two main categories; Electric coil or pressurised butane gas jet flame lighters. Here at Dragons Head Shop, we have both types, the electric coil or USB rechargeable lighters used mainly for cigarettes, cigars or rollups. By pressing a button the Tesla coil heats up, glows red and by holding your cigarette to the coil of your USB rechargeable lighter the conducted heat from the coil ignites your cigarette.

temperature to produce a cleaner flame and is ignited by a spark which is created simultaneously that passes through the pressurised butane gas which is released when the jet lighter is operated.
