Aquarium heaters are sometimes made of borosilicate glass. Due to its high heat resistance, it can tolerate the significant temperature difference between the water and the nichrome heating element. [citation needed] Specialty glass smoking pipes for cannabis and tobacco can be made from borosilicate glass. The high heat resistance makes the ...
The first modern aquarium made of glass was developed in the 19th century by Robert Warrington. [44] During the Victorian age, glass aquariums commonly had slate or steel bottoms, which allowed them to be heated underneath by an open-flame heat source. These aquariums had the glass panels attached with metal frames and sealed with putty.

[1] It is available in a number of colors, and may be naturally colored or dyed, and may have a polymer seal to ensure it does not affect water chemistry. [1]
