What are the details surrounding the brass brazier required for the Find Familiar spell?

In our campaign, I play a warlock and brass braziers are hard to come by. I want to carry a brass brazier in case my familiar dies and I need to again cast find familiar.

  1. How bulky is a small brass brazier? Can it be carried for several weeks without hindering long distance foot travel? That is, because of its shape or weight, does the typical brass brazier reduce my speed?
  2. What’s the price of a small, simple brass brazier?
  3. How long would it take a brass worker to make a small, simple brazier? How long would it take the brass worker to make one specifically designed to be eminently portable? In both cases, assume the brass worker works nonstop exclusively on the brazier.

What I’m looking for are references, similar cases, and information that can help handle these issues properly and accurately. First and foremost in D&D 5e (especially RAW) and then other RPGs and even real world, if they could be used to make estimates about the answers to these questions when we compare how similar cases translate to D&D 5e mechanics.
