I'm also continuing my research on the impatient sawer vs the saw blades.
I'm getting better. I will be reporting back on my discoveries. I am
trying out all the hints you've sent me (THANK YOU!) and for the most part
you guys are sooooo smart. I am sooo glad I ask these questions.
Later.

When the brass is liquid the zinc comes off as fumes which are toxic (heavy
metals). This causes the brass to zinc poor if it is not replenished. Safer
to stick to bronze...more humane to avoid ivory 8^)

- Reticulation of brass works very similar to that for Ag.
NOTE: Fumes can be dangerous and anything that is heated (especially any
metals), should be done with ventilation.(other additives are likely to
be in the brass besides Cu & Zn which become toxic upon heating and release)
I find that the texture is often quite nice and you can get a good selection
by using varying thickness and using "large" sheets (15x15 mm). Cu tends
to migrate to the surface, but pickling in Sparex, carefully wire
brushing, and then cleaned with dishwashing liquid and a toothbrush work
quite well. Also the metal doesn't tend to flow as well as sterling
because of the high Cu content, so some experimentation works best and
the brass is a lot cheaper than Au. (Cu sheet works ok too, and the heat
patination that you get are often spectacular)
Sometimes I have even Au plated the brass to get a richer look,
that works well when combined with other elements of a piece (such as
sand blasting or patination.)

Word of mouth has it that simple respiratory filters are no good to protect
you either. This is why there are quite a few bronze casters and not many
brass casters (I mean people don't want to play with it as opposed to a
Darwinian thing).
Thanx for justifying my brass toxicity warning. mbm
