There seem to be a couple of answers to this question, depending on where you're from. In the UK, herculite is hard-setting plaster used to make plaster buildings for war gaming and architectural details for dollhouses.
It can be used with silicone molds to create inexpensive terrain / scenics / miniatures.

What is the Difference between herculite tempered glass and herculite tempered safety glass?
Herculite tempered glass is a type of tempered glass that has been processed to increase its strength and safety. Herculite tempered safety glass is a specific brand of tempered safety glass known for its durability and resistance to impact. The main difference is that Herculite tempered safety glass is a branded version of tempered safety glass, possibly with additional features or specifications.
What is a herculite door?
A herculite door was a particular manufacturer of a frameless glass door. This would normally consist of 1/2" tempered glass with the vertical edges polished. Tops and bottoms are pivoted by either patch fittings or full width shoes, often with polished metal cladding. These are hi profile doors you might see at a lobby, or mall entrance, or perhaps an executive office. People often recognize frameless glass doors as the age old term herculite door.
What is herculite tempered glass?
thick commercial glass panels formed under pressure. when cooled the temsion of the pressure is locked into the crystal structure making them very resistant to damage from a blow to their faces (but not to their edges and edge corners)
What type of glass is used to make bus shelter?
Glass shelter should be protection from weather. Parts should be easy to reorder and replace and should not require removal of other parts or sections for access to make the repair. Materials should be vandal, graffiti, weather, salt, and rust resistant, and easy to clean. Herculite glass side panels are strong, shatter-resistant, and easy to clean.
What are the advantages and disadvantages of latex casting by using Plaster of Paris mould?
The following assumes we are discussing the Slush Casting Method. The primary advantage of using Plaster of Paris Moulds with casting latex is their porosity. The latex solids are drawn to the face of the tool quickly, as the water and ammonia soak into the plaster. It is essential to have a DRY plaster mould to do this with. Once allowed to deposit latex solids for some time, which varies from latex to latex based on their solids content, the remaining mix is poured out. Grades of latex go from Cheap Moulding Latex > Cream Latex (40-70% solids variation!) The next advantage of a PoP mould is the speed which latex dries within it. Being fully porous, this allows the latex to dry from "both sides". Also the fact that the water/liquids disperse within the plaster. The whole mould then becomes a drying surface. The main disadvantage of PoP moulds is mould longevity. Plaster of Paris is a Beta Plaster. This means the plaster is essentially weaker. Its second main disadvantage is fine details can be lost to the larger particle size and therefore definition. To combat this try to find a harder plaster, but the balance is fine. Too hard and the porosity drops. In the UK Herculite 2 is a good balance, but Plaster of Paris (Fine Casting Plaster by British Gypsum) is cheap and readily available -ebay or a web search for british gypsum fine casting or herculite 2 will see you right!
