Just use a glass screen, you can buy them at a headshop for probably 2$. They are small glass jacks and u just drop it into the bottom of the bowl and it covers some of the whole.
Mex Reviewed by Mex on . Epoxy I have read that one person has actually "epoxy'd" a screen permanently into their bowl, and I may do the same thing. I am looking for some opinions as to if this is safe or not and what type of epoxy to use. I am using a glass bowl. Rating: 5
