I finally received My glass piece from PipedDaddy (better said: from the customs) it's their "vapor glass bubbler". It's SO tiny! Perfect for my use at the moment since it has to mate with an MFLB. MiniVAP is also present, got it today too and I cant wait to try it! I'll use the bubbler with a Ti Nail (between the bub and the MFLB). I used the nail first some days go on a bong. When I heated it it became red (ok), but after the use I noticed it has some blue residue/color on it. I think it's normal at least for the first uses mostly because that blue color is also present on www.doyoudab.com website. Does it mean I overheated it? How much do you have to Heat a nail? I made it to become red, than While I put the dome over it everything ready it cooled down so I re-heated a little bit and then I dabbed.
