Not all glasses are created equal.  The hand finishing of a pair of frames is a long and complex process.  While many frames today are mass finished using chemical vapor baths, we put every frame through ten individual steps just to get the final finish.  We think it's worth it, because nothing comes before quality.


Steps 1-4 : Barrel Tumbling

The barrel tumbling process works like sea glass.  The frames spend four days (one day in each barrel) to remove tool marks from when they are cut, soften sharp corners and add a high quality finish to the acetate.

Step 5 : Sanding

The frames then move through several more steps and are then assembled.  We craft every pair to make a seamless connection between the front and the temples.  The first step in this process is to gently flatten the connection through sanding.

Step 6 : Hand Filing

After we get the connection close on the sanding belt, we hand file every pair to make sure that the connection is perfectly flush.  Here at Lowercase, we consider this a true sign of quality and craftsmanship.  

Steps 7 + 8 : Felt Buffing Wheels

We use two different felt buffing wheels to smooth out the connection that was filed and remove any filing marks or burrs.  First we use an aggressive wheel, then a more gentle wheel to smooth out the acetate.

Steps 9 + 10 : Polishing Wheels

After the connection is crafted, the frames move on to receiving their final polish.  We use a two step process - first to smooth out any minor scratches or imperfections on the frame, and then a final polish to give the frames a solid shine.

After the final polish, the frames are ready to be fit with lenses, wiped down, and shipped off to you!
