some forms of fine chain are made just this way. However, there
are many types of chains and some of them are not ever soldered
or fused. An example of this is the idiot’s delight. The loop in
loop that has been talked about is composed of soldered or fused
loops that are elongated, folded, and inserted into another one.
In fact, the loops can be assembled in multiples of twos, threes,
fours, and more. The simplest is one into one and is similar to
some brass chains that I have seen in hardware stores. I think
they might be used in double hung windows.
