Do you plan on adding copper into the pure silver to reduce it to 925? I started with a Bernzomatic TS4000 when melting silver, but it didn't do copper to well... When I needed to replace that one I got a dual torch like this from Amazon. It works with propane as well, which is much cheaper and can melt down several ounces of silver in just a few minutes.

It depends on where I want the 'button' and how much clean up I need. Pouring from the side places the excess button on the edge of the piece instead of the middle of the back. Easier to clean up. I saw it in https://www.amazon.com/dp/B08RXY4JXH Thanks
Had a good deal with good reviews, and had the most that came with it. Will see how good it works this weekend if I don't get too itchy tonight
I used my buddies casting equipment like this one
Cast Iron 2-Piece Flask Mold Frame for Sand Casting Jewelry Metal Casting Making Tool https://www.amazon.ca/dp/B018ZMI7TA/ref=cm_sw_r_cp_api_fabc_tGK0FbQEEACKR Just make sure you make a good sprew opening and cut vents around your casting. The hot gases need to escape so they don’t cause bubbling
For 925 Im only doing rounds. I use a dremel wire wheel and clean it up and then wet sand it with 600-2000. After patina or plain - I use this polish which works well.

If you mean those little disposable oxy tanks, then no. They are not cost effective. Amazon has them for $35 (!) and they have less than an hour's burn time, depending on the size torch. One person in the reviews said 10 to 15 minutes. Another "Our OX9 cylinder is 1.4 oz. It should also be noted that our oxygen tanks are designed for smaller projects. Since fuel burns at a much higher rate than propane, they generally work at a 4: 1 ratio compared to propane."
Get yourself a little oxy/acetylene setup. I found one for less that $100 on Craig's list with a carrier. Got some cheap regulators in EBAY, and found a free golf cart to finish it off.
I purchased this one https://www.amazon.com/dp/B0036E9VB6?ref=ppx_pop_mob_ap_share because it comes from a decent manufacturer. There are ones for half the price, and if you have access to a harbor freight or tractor supply that might work.
Good. When I first started I went through 5 dishes before I figured it out. When I bought this everything went so much better.
I bought pure talc from Amazon. Works well and doesn't smell like a baby's ass. https://www.amazon.com/gp/product/B08LZ4XBLR/
I cut up an old t-shirt and made a "puffball" that I could pat onto things for a light dusting.
Is your stamp offset? I have heard thathelps:
Also available on Amazon
Once it's out of the flask it comes off pretty easy I polish with the 3m rubber publishing wheels like these There is a mild acid that is supposed to be good at breaking this stuff up but I haven't tried it yet https://www.amazon.com/BUYGOO-Abrasive-Bristle-Brushes-Mandrels/dp/B07G8WC2QF/ref=mp_s_a_1_5?keywords=3m+polishing+disc&qid=1573009011&sprefix=3m+polishing+di&sr=8-5
Upon deep reflection and a couple of beers, it came to me that you want a book, "Practical Casting: A Studio Reference" by Tim McCreight. Seriously, don't buy anything until you get this book.

I was thinking, you may want to try sling casting. Nothing says fun like 1800 degree molten silver flying through the air!
I live in Canada so I have to get it shipped of Amazon.ca, are both of these products the same as the one you linked? The reason I asked is because the prices are significantly different to each other:
a lazy susan is a flat table that can be rotated, usually used int he center of dining tables to carry commonly used condiments.
easiest way, mount this to your bench, mount a board to the top of it, mount your bottom mold (the cope) to the board.
http://www.amazon.com/Capacity-Bearing-Turntable-Bearings-VXB/dp/B002TIKEQ6
spinning the mold forces the silver to run to the outer areas, in this case deep into the ring mold forcing the silver to reach every area, the oversized sprue is acting as a reservoir so you don't end up with shrinkage porosity ruining the piece.
