Tikro volframo karbido ziedai turetu suduzti nukritus ant zemes. O spalva ju turi buti pilka matine. Buitinis tikro volframo karbido pavizdys- graztu antgaliai, tekinimo stakliu "dantys".

Todel cia kazkokia xuinia.

Bet jei nori bandyti, karbidas visiskai inertiskas metalas. Bet jis nera spalvotas ir grazus.

Nori kruto metalo? Jamk Tantala- bandziau pjauti tantala su volframo karbidu. Karbidas pralaimejo.
