Do I have to have a steel bath tub to dissolve a body with hydrofluoric acid ?

not that I need to do so......lolololDo I have to have a steel bath tub to dissolve a body with hydrofluoric acid ?
Well, wiki says it has to be stored in either polyethelene or teflon coated containers, so I guess the tub would have to be coated with one of those if you didn't want to lose the tub along with the body... oddly, they don't say the proper kind of bathtub to use.





from wiki:





';Hydrofluoric acid is notoriously known to dissolve glass by reacting with SiO2, the major component of most glasses:





SiO2(s) + 4HF(aq) 鈫?SiF4(g) + 2H2O(l)


or





SiO2(s) + 6HF(aq) 鈫?H2[SiF6](aq) + 2H2O(l)





Consequently, it must be stored in polyethylene or Teflon containers. It is also unique in its ability to dissolve almost all inorganic metal and semimetal oxides.';Do I have to have a steel bath tub to dissolve a body with hydrofluoric acid ?
You should have a plastic tub, preferably polytetrafluoroethylene (Teflon), or a ceramic-coated steel tub, or a tub coated with paraffin wax. HF(aq) will attack steel.
Hydrofluoric acid will attack steel -- and almost anything else. One exception is wax, so the stuff is shipped in wax-lined bottles.
A steel bath would not work. A Stainless steel tub can be used, as well as polypropylene, which would be less costly.
