Jared of J-Red Glass is a native of Washington state, and has been in the glass industry for over 15 years. Working with different glass techniques and styles over the years, he produces beautiful functional and non-functional art. He recently began experimenting with the quartz banger concentrate nail design, and came up with the revolutionary Diamond Knot. Diamond Knots quartz nails by J-Red Glass are the first domeless concentrate nail that does not require a carb cap for use. 100% American quartz Diamond Knots are designed for exceptional dab flavor and heat retention. Place your rosin, wax or bho around the outer ring and let your dab drip down the cut fins. Diamond Knots are available with either a regular, XL or Triple Stack diamond knot head with male or female joint. His latest innovation is the Thermal Diamond Knot Pan and Bucket quartz banger nails, which feature the benefit of thermal heat retention, making them an ideal choice for low temp dabbing.
