The element that erodes glass in both hydroflouoric acid and etching cream is flourine. Hydrofluoric acid is very dangerous to handle, and requires special training and the use of proper equipment. "Etched Glass" by Norm and Ruth Dobbins states that "...borosilicate takes a bit longer to etch than soda lime glass. Some etching creams do not work on borosilicate." The fumes from this acid, when inhaled, will destroy lung tissue. Skin contact is painful and causes lasting mutilation. Here's some information on etching.
