Harnessing modern glassblowing technology for you to create brilliant music with the “Sound of Glass”.

Through creative innovation & quality craftsmanship, we strive to produce outstanding glass guitar slides and picks that compliment your sound and style. Silica Sound is the original handmade glass guitar slide made with a tapered fit, since 2003. Handcrafted in California, U.S.A.

Silica Sound glass guitar slides are handmade with a thickened end to promote a unique grip on the tip of your finger, as well as added mass for better sustain. They are unlike any other glass guitar slide in the way they feel, sound and look.

Choosing Your Model & Sizing Information


We offer 10 different slides: Models #418 - 428. This presents a lot of options, so here's a few easy things to help you decide which model will fit you best.

Simply put, we use glass with 2 different wall thicknesses, and there a few different sizes (such as large/small and short/long) in each of the 2 different wall thicknesses. 

The tapered interior and length of slide can also be tailored to your specifications.

For online orders, please take a few moments to make sure you have properly determined your slide sizing. This will avoid exchanges due to sizing issues, saving everyone $$$.


Slide Model Sizing guide

It is best to first determine which model will fit best. We have made a simple, downloadable guide to help you with sizing.

Just click on the Slide Sizing Guide image to get the pdf.

Print it out and follow the directions.

Make sure it prints at 100% (actual) scale. Please check print settings and correct if necessary. Measure the width of Template 1 (2.6") to check for accuracy.


Customizing your slide

We can create a custom fit for you by controlling the inner diameter of the colored end of the slide, or by cutting the slide to a custom length.

This option is FREE for international orders. Just add it to your order, and we will refund the charge once you place the order. Please take advantage of this so your slide fits well!

Some tips on Taper Sizing:

First, determine which model you want, then measure for taper sizing. One of the easiest ways to find your Taper Inner Diameter, is to use the Slide Sizing Guide above. 

Alternatively, you can try these methods:

(1) take a piece of string, piece of paper, or a clothe/flexible tape measure, wrap it around your finger where the taper will rest (usually near fingernail or first knuckle), and measure the circumference around (millimeters preferred). Be as accurate/precise as possible

(2) divide your measurement by 3.14 (pi) to get your "Taper Inner Diameter"

Or, If you have access to a pair of calipers, measure the diameter of your finger where the taper will rest.

Taper Diameters tend to be in the range of approximately 13-17mm.
