The Weld-On 4 you used for the dichloromethane (AKA Methylene Chhloride) is only 30-60% DCM: https://www.tapplastics.com/uploads/pdf/MSDS%20IPS%20Weld-On%204%20New.pdf A cheaper and more concentrated source is Klean-Strip Premium Sprayable Stripper: http://www.homedepot.com/p/Klean-Strip-1-gal-Stripper-GKS221/100207981 It has 60-100% DCM: http://www.homedepot.com/catalog/pdfImages/1e/1eefe9ef-a288-415f-974a-5852129185cf.pdf I have a suspicion that the "Liquid Quartz Glue" you used is merely a more concentrated formula of the same chemical.
