making crystal geodes with borax

so there's a lot of vids on this on youtube but they always use a glass beaker for heating the solution. i don't have a glass beaker and would rather not buy if i don't have to. my question is, can i just heat the borax-water solution in an aluminum/steel pot instead?

i know boriatic acid is caustic but that's borax+sulfuric acid. this solution is just borax+water…. your thoughts?
