Durability testing

Eternity's performance has been tested within a broad scientific research programme.

In the first test, pans were immersed in oil heated to 200 °C for 24 hours. No part of the non-stick or enamel surfaces of Eternity products was damaged.
In the second test, milk and egg were cooked in the pan with no lubricating agent whatsoever. The surface showed excellent non-stick behaviour and cleaned easily.
The surface was then scored with a knife at 2 mm intervals; after adhesive tape was applied and pulled away, no part of the non-stick surface lifted. This test was repeated 25 times.
After 60,000 spatula scrapes the Eternity pan retained its non-stick properties; the competitor pan tested alongside it lost them after 3,000.
SCRAPE TEST: the surface of the pan was rubbed with a metal spatula, imitating the motion of cooking an omelette. After 60,000 cycles Eternity still showed excellent non-stick behaviour. At various shows this figure has exceeded 200,000 cycles.
ABRASION TEST: carried out by scouring the wet non-stick surface with a cleaning implement. On Eternity products, surface wear appears only after 1,800 repetitions.
CUTTING TEST: the surface was scored with a crescent-shaped carbide cutter. The force required to pierce Eternity's base was found to be 26 newtons, beyond which the base was damaged.
STAIN RESISTANCE TEST: conventional non-stick coatings are prone to staining, particularly in light colours. In this test an Eternity roasting tray was held at 315 °C for 36 hours, and retained its resistance to both high heat and staining throughout.

The tests show that Eternity is up to 20 times more durable.
