Zigmant J. Kanstul (1929–2016), Founder  After 38 years Kanstul closed it’s doors in February 2019.  I would guess this horn to be 7 years old and made by hand.  Read, and see how the copper bells are hand made.

Sheet copper has been cut to shape and then soldered together down the middle. You can see the seam going down the length of the bell. This process is very much like making clothes. They use a pattern to cut the sheet metal to the proper shape. Its hard to believe that these will be beautiful copper trumpet bells. Its hard to imagine these will be beautiful trumpet bells. They will be, after the bell maker is done spinning them on his lathe. Remember the best instrument making is still done by hand not computerized machines. Many of the techniques you see here have not changed in hundreds of years.The material is hammered so it bends around. The two two edges must come together and actually overlap, in order that they can be joined permanently. The two edges are then heated red hot and soldered together. The bell is soldered with a brass solder, which is yellow in color. This makes a yellow line which is invisible on Brass bells but really shows up on Copper bells because of the color contrast.

So now you know why there is a yellow line all the way down the full length of al ZeuS Copper bells. It is the visible seam. Its a sign a beauty and wonder because this is the traditional way to make bells. This is the way they made them for hundreds of years as far back as the Renaissance and even before, as long as there were brass instruments. If you visit any museum in Europe and view historic instruments you will see the pronounced seam on each and every instrument.  It sure is a sign of beauty and pride to know that your instrument was not just stamped out but hand made the old world way. Just like they had done it for hundreds of years. This is the real way to make a bell.
