Această reacţie este cunoscută drept ”vipera faraonului” sau ”şarpele faraonului” şi este cauzată de descompunerea mercurului pe măsură ce arde. Este un exemplu de reacţie intumescentă, care duce la umflarea unei substanţe ca urmare a expunerii la căldură.
O reacţie similară este folosită pentru popularele artificii ”şarpe”, însă companiile nu mai folosesc mercurul deoarece fumul este toxic.
