Each one of our glass guitar accessories are handcrafted and shaped in the flame by Chris Davidson. He has been blowing glass since 2001, and has a passion for making the highest quality gear for guitarists in their quest for tone and feel.

We use a glassblowing torch to melt and condense the glass, which forms our unique tapered interior. This provides a snug fitting slide, and also adds some eye-catching appeal. It also adds extra mass to the slide, making them superior in tone to any other borosilicate slide. Silica Sound is the original glass guitar slide made with a tapered interior, since 2003.

The tapered interior slides are typically used with the taper at the tip of the finger. This gives a great grip, keeping the slide snug and stable on the finger. It also gives a great feel to the weight and inertia of the slide.

They can also be used with the tapered end at the base of the slide finger. They have more of a Coricidin bottle feel, and have a great grip. Usually, a larger slide such as the Model(s) 425, 426, & 428 and a wider taper is necessary for this.
