Malo više o kanthalu:
"Kanthal A-1

Kanthal A-1 is a ferritic iron-chromium-aluminium alloy (FeCrAl alloy) for use at temperatures up to 1400°C (2550°F). The alloy is characterized by high resistivity and very good oxidation resistance.
Typical applications for Kanthal A-1 are electrical heating elements in high-temperature furnaces for heat treatment, ceramics, glass, steel, and electronics industries.

Kanthal A

Kanthal A is a ferritic iron-chromium-aluminium alloy (FeCrAl alloy) with high resistivity and good oxidation resistance for use at temperatures up to 1350°C (2460°F).
Kanthal A is typically used in industrial furnaces and home appliances. Examples of applications are elements embedded in ceramics for panel heaters, infrared heaters, warming plates, irons, ceramic pots, in cartridge heaters for liquid heating, storage heaters, in ceramic heaters for cooking plates, air guns, hobby kilns, radiators, in quartz tube heaters for space heating, toasters, toaster ovens, grills, industrial infrared dryers, coils on molded ceramic fibre for cooking plates with ceramic hobs.

Kanthal D

Kanthal D is a ferritic iron-chromium-aluminium alloy (FeCrAl alloy) for use at temperatures up to 1300°C (2370°F). The alloy is characterized by high resistivity and good oxidation resistance.
Kanthal D is used in home appliances and industrial furnaces. Typical applications in home appliances include metal sheathed tubular elements for dishwashers, elements embedded in ceramics for panel heaters, cartridge elements in metal dies, heating cables and rope heaters in defrosting and deicing elements, mica elements used in irons, quartz tube heaters for space heating, industrial infrared dryers, in coils on molded ceramic fibre for boiling plates with ceramic hobs, in bead insulated coils for panel heaters, in suspended coil elements for air heaters in laundry dryers. "

Dakle treba lokalno postić temperaturu hiljadu i četristo stupnjeva da ispari (MTM store A1 kantal) :D

Valjda kužiš da se radi o 360 st. Celsiusa a ne o 1400 :) .
Tj. ne radi se o isparavanju khantala nego o heksavalentnom kromu.

btw. Ne vjerujem da postoji realna opasnost za zdravlje :D
