About Us

Chris Davidson has played guitar since the age of 12, and in 2001 he started learning to blow glass at Jerome Baker Designs in Eugene, OR. In 2003, the lack of options for a good fitting glass slide drove Chris to use his craft in glassblowing to develop the slides you see today.

During initial research & development, he found that the process of adding colored glass to the slide and then melting it in, inadvertently formed the snug-fitting tapered interior while keeping the exterior uniform and smooth. It was also a nice surprise to find that the added mass at the tapered end of the slide gave it a great tonal quality, separating it from all other borosilicate glass slides on the market.

As luck would have it, the slides also bore the resemblance of a ‘pipe’ or ‘bong’ that this type of glasswork is known for, so it was naturally fitting to give them Model Names surrounding one of his favorite numbers, “420”.

Thus, Silica Sound (The Sound of Glass) and the original glass guitar slide with a tapered interior was born.
