The Titanium Matrix Bowl is a hybrid glass and Titanium bowl designed for use with the Thermal and Ruby Twist, along with the Wireless One Hit Wonder. The bowl comes as standard with a 14.4mm male glass joint attached and an 18.8mm glass joint in the box. 10mm joints are also available as are Spare Glass adapters/joints. This style of bowl provides all the advantages of a Titanium bowl with the ability to heat soak for hybrid style hits from your Thermal/Ruby Twist but without the disadvantage of traditional metal bowls which expand and get stuck in the glass joints of your bubbler. We have adjustable height mesh basket screens available, linked below. With these you can adjust the height of the screen inside the bowl to make the easy dosing. Just don't set it so high the herb is touching the heater!  If purchasing this with a Thermal Twist or Ruby Twist Full Kit, please use discount code "MatrixBowl" for 15% off the Matrix Bowl.  If you previously bought a Thermal or Ruby Twist Kit from us please use discount code "MatrixEarly" for a 15% off discount code.

This has been cleared by Vapvana for use with other designs such as the bowl in this listing! Please note To remove the screen from inside, simply poke it out with something from the underneath, towards the top of the bowl. The bowl doesn't need to be disassembled to remove it! The joints on these bowls can be quite stiff to remove. We've found the best way is to grip the glass joint and bowl firmly then pull steadily apart, don't wiggle or twist. Once it's apart you can add a little o-ring lubricant, Flower Mill wax, Dynawax or similar to the o-rings to make it easier the next time. If you're really having trouble you can use thermal expansion to assist; place your Thermal or Ruby Twist housing onto the bowl for around 15 seconds to heat it up, then hold the Titanium part with an oven glove or towel and pull the glass joint out as described here.
