Dragonglass Lamps
Mechanics & Inner Workings
Dragonglass lamps make use of stored magic energy in the dragonsglass itself as a form of battery, that when released into the chamber of the lamp, creates a bright light without any significant heat, risk of combustion, or expelling any gasses or waste other than a depleted piece of glass that can be refilled and reused. Many areas that have potent excesses of magic may install refueling stations for refilling the dragonsglass cartridges and resealing them in order for reuse, making reuse of the lamps fairly easy for even infrequent users of the product. All cartridges for dragonglass lamps are regulated to be under 1 pound even in the largest models, to fit with safety regulations.
The lamps work in a wide array of conditions and do not require an external power source, and have become quite popular as both a method of utilizing 'waste' magic and long term lighting, as most lamps can last for days at a time. Most commonly, they are used as semi-permanent light fixtures, due to not being able to be turned off once lit, such as for emergency lighting, lightposts, sign illumination, or land markers. Mermidae settlements in particular are quite fond of the lamps due to them working easily under water, and their long lifespans mean that the need for a recharge station is rather infrequent, and discharged chambers can be saved until regular trading with ships or shoreline settlements.
Manufacturing process
All lamps are constructed by use of a dragonsglass battery or cartridge at their center, held within a bulb of the same material to contain the magic released. These bulbs are generally filled with gasses that react to magic, producing light when in contact. The cartridge or battery will have its seal broken when the lamp is triggered to its 'on' state, usually by a striker that pierces the seal.
