is in the description :The problem is there is nothing to reference scale in the photo. The stainless table may be worth more than a few grams of metal. And act as a constant reminder of what not to do.
Its a brand new heavy duty stainless steel bench! I honestly didn't imagine it would weld up so fast.Do you need to save the stainless, or can you just cut the plug out?
Sure will be a reminder! yeah over 3 grams. I soaked a papertowel with HCl, covered it with a plastic cup for about an hour and it loosened up enough to get a chisel under it. Got the majority off but there's still at least 0.25 gramsThe problem is there is nothing to reference scale in the photo. The stainless table may be worth more than a few grams of metal.

Mr. chisel! Low tech but effective.Sure will be a reminder! yeah over 3 grams. I soaked a papertowel with HCl, covered it with a plastic cup for about an hour and it loosened up enough to get a chisel under it. Got the majority off but there's still at least 0.25 grams
Don't know. I would be afraid I'd have a real clean button welded to my table.. At least when I sell the table I can advertise it as having 24k gold inlays.Wouldn't it move if you sprinkled borax on it and around it and heated it with a torch?
If you soaked a paper towel in AR and covered the gold you will risk dissolving some gold.Sure will be a reminder! yeah over 3 grams.

What if I soaked a paper towel in AR and covered it overnight? ....would I just make more of a mess?
We call it sheetrock over here in the US."I'm not sure what you call plasterboard over in the US, but it's Gypsum with card outers. "
Hey, thanks! Well the fireproof stuff would be perfect. It's not going to be permanent of course but it'll catch your gold perfectly.We call it sheetrock over here in the US.
They make sheet rock in regular, waterproof, and fireproof.
If your "melt" bench is outside fumehood, I would opt for non-fireproof version. Flame retardants are nasty halogenated compounds, and they decompose to HCl, HBr and whatever toxic organic junk as they burn/heat up. Considering that hot things on melt bench dropping onto it are quite regular thing (crucibles, slag/metal spil, accidental pointing of torch towards board etc...), you will be steadily breathing small quantities of nasty smoke over the years.Hey, thanks!

"Sheetrock" is a brand name. It's all fire resistant and as far as I know type X has fiberglass, type C has fiberglass and vermiculite. It's used for demising walls and utility/elevator shafts/stairwells. Fire ratings are variable depending upon the occupancy classification, but 5/8" drywall gives an hour burn rating.If your "melt" bench is outside fumehood, I would opt for non-fireproof version.

Underlayer is gypsum, which is fireproof enough (in my opinion) for small accidental spills.
We used to use larger steel tray/catchpan, several centimeters high, filled with few cm layer of clean sand. However we did some larger smelts where several liters of melt could potentially be spilled. Sand is very good at containing spills of molten material - melt does not just flow away, and heat is evenly dissipated. Potential metal spills are easily recovered by panning.
BTW, correct me please, doesn´t it also called drywall ? Gypsum between two pieces of thick paper/cardboard, sold in large "sheets" for construction of interior walls ? Or I am wrong
