So I just got my very first piece. It's a 6' roor bubbler with percs. It's a rather plain bubbler and I have come up with the idea to paint it with paint pens. The pens can be cured on glass by putting in the oven at 160*C for 45 minutes. Is there a chance that the heat of the oven will break or crack the fragile percs? There is a bit of water left in them but I suppose I could wait till it entirely dries out.
I wouldn't do it. You'll regret it later and if it looks stupid youll be stuck with it. I would let it stand upon its own legs.
