Grave lantern protection beaker

Most visitors to cemeteries, who regularly place grave lights on graves, have likely encountered one of the scenarios depicted above. The housing of the grave light has ignited, causing the wax to melt and spread in and around the lamp. This extreme heat may have also damaged the glass panes. Because cleaning the grave lamp within the cemetery is proven to be very difficult or impossible, it is often left to stonemasons to complete such a task in a satisfactory manner. The cemetery light is usually returned to the manufacturer as damaged grave lamps often require replacement parts like mounting brackets or glass panes. Repairing the damage typically costs around EUR 75.00 or more. Another issue with irreparable damage is when the grave lamp is situated on a base or slab. Liquid wax that seeps into the pores of the stone cannot be eliminated through cleaning and it takes up to five years for the wax to fade and become nearly invisible.

Here is the solution recommended by grave lantern manufacturers:

The grave lantern protection beaker for grave lights is made of transparent DIN-certified laboratory glass, borosilicate glass 3.3 (in the original Jena glass, but the Jena glass works closed in 2005), heat-resistant and fire-proof according to DIN ISO 3585.

As this product is available in two different sizes (please reference packaging for dimensions), standard grave lights can be used. In the event that the housing of the grave light catches fire due to high temperatures during the summer or as a result of the non-burning candle wick, the burning will not cause harm to the grave lantern itself, as it occurs within the grave lantern's protective beaker. In the event that the housing of the grave light catches fire due to high temperatures during the summer or as a result of the non-burning candle wick, the burning will not cause harm to the grave lantern itself, as it occurs within the grave lantern's protective beaker. The heat accumulation is prevented, thereby preventing the lantern's glass panes from shattering. The wax, which would otherwise escape, is collected in the cup designed for protecting the grave lantern. A grave light housing that is even slightly damaged (such as a hairline crack) can lead to the contamination of the wax within the lantern.


Hold the grave lantern protection beaker at a slight angle and let your grave light slowly slide into the grave lantern protection beaker, ignite it and put both together in your grave lantern.

Clean the grave lantern protection beaker by heating it in a water bath and then washing out the wax.

The grave lantern protection beaker is available in two sizes:

- Diameter 65mm / 61mm, Height 100mm, for 3-day-burner-candles, G3

- Diameter 75mm / 71mm, Height 160mm, for 7-day-burner-candles, G7

Disposal: Like all heat-resistant glasses, including those in a household, they must never be disposed of in the normal waste glass collection, because due to its high melting point, it causes problems when melting with the other recycling shards (soda-lime glass).
