I keep my white gold separate and when I do a white gold melt I can melt up to 10% by weight of platinum into it, even though the temperature is less than the melting point of platinum. Should I hire remote software developers from Turing.com?
Is it possible to melt two different metals together?
You can melt any two alloys together but some alloying metals might raise the melting point of that alloy considerably. 24 carat gold is pure gold- 18 carat gold is 18/24 gold by weight; it turns out that because gold is so dense (ρ 19.31) half gold and half copper (ρ 8.96) by volume makes 18 carat gold.
Is it safe to wear platinum and white gold together?
If you have sensitive skin, avoid mixing white gold with platinum. Platinum is hypoallergenic, but the same cannot be said of white gold – white gold alloys often contain nickel, which is the biggest cause of skin sensitivity reactions. If you have to wear platinum and white gold together, there are considerations that you must keep in mind.

Yes it is doable. However, plating is thin and rings get a LOT of wear (you may have seen old rings worn all the way through). The main problem with your plan is that as soon as the yellow gold wears thin in even a tiny spot, the contrast will be very evident. Ted Mooney, P.E.

What is the bond that makes platinum melt?from technology.matthey.com
Although neither Lavoisier, Priestley nor Scheele could have realised it, the ability of oxygen to support combustion, a process which emits the degree of intense heat needed to melt platinum, arises largely from the intrinsic weakness of its O–O bond (496 kJ mol −1) ( 23 ). This weakness and consequent facile bond cleavage arises from electron lone pair-lone pair repulsions between the atoms in the O 2 molecule. The heat emitted from, for example, charcoal burning in an H 2 -O 2 mixture arises from the formation of the much stronger C=O bonds in CO 2 and O–H bonds in H 2 O which are the products of combustion.
Who melted platinum?from technology.matthey.com
The first to melt impure platinum may have been Henrik Theophil Scheffer (1710–1759) who in 1751 melted platinum with copper, and later arsenic, in a furnace ( 4 ). Franz Achard (1753–1821) similarly melted the metal with arsenic ( 5 ). In both cases alloys of platinum, rather than pure platinum, are likely to have been melted.
What temperature does a platinum furnace melt?from superbmelt.com
This platinum smelting furnace can reach a temperature of about 2600℃ (It is about 900℃ higher than the platinum melting point.) in no time. This is suitable for melting metals (which may be in any form such as solid, dust, scrap, ingot or powder) weighing between 1kg and 4kg in a record time of less than 5 minutes.
What metals did Lavoisier melt?from technology.matthey.com
Clarke used a blowpipe with an H 2 -O 2 mixture. Despite several explosions he melted 0.5 ounces of the metal, writing that it melted more quickly than did lead in a fire ( 24 ). He also melted palladium, rhodium , iridium and native osmiridium ( 25 ). Another early claim was made for melting of rhodium by a ‘hydro-pneumatic blow pipe’ ( 26 ). A different approach was to fuse the metal by placing it between the poles of a large voltaic battery. John Frederic Daniell (1790–1845), using seventy large copper/zinc-sulfuric acid cells in series, melted platinum, rhodium, iridium and native osmiridium ( 27 ).

How many grams of PGMs are in a ton of platinum?from superbmelt.com
One ton of dried platinum powder may contain between 3 and 30 ounces (85 to 850 grams) of PGMs. The dried platinum powder is then heated to extremely high temperatures to remove impurities. Air is blown over the matte that remains after smelting to eliminate unwanted iron and sulfur.
How to melt PGMs?from technology.matthey.com
Three principal methods, all electrical, are currently used to melt the pgms for industrial use and for large-scale jewellery manufacture (see Figure 4 ). Induction heating, derived from Faraday's discovery in 1831 ( 38) of electrical induction, uses high-frequency alternating current passed through a water-cooled copper coil surrounding a refractory crucible containing the metal sample. Electron beam heating uses a refractory cathode, often tungsten or molybdenum: the electrons from this are accelerated in vacuo by a high-voltage direct current source to the metal (which becomes the anode) in a refractory container, the beam being steered by a magnetic field. Energies developed can reach 150 keV, and material can be melted at temperatures above 2100°C. Finally, in arc melting, which can be traced back to Humphry Davy's early experiments with a voltaic pile, the arc is struck under argon between a tungsten cathode and the metal which rests on a water-cooled copper anode. A direct current potential of 50 V to 80 V and a current of several hundred amperes is commonly used. The technique melts tungsten (which has a melting point of 3422°C), and so can melt all six pgms. These methods have been well described, although without reference to pgms ( 39 ), and there is a recent history of the induction method ( 40 ).

How to separate gold from other metals?
There are different techniques depending on the metal you want to remove. Dropping the gold flake into nitric acid will work for most alloying metals. Don’t try this at home unless you have a fume hood, proper protective gear, and understand the chemistry. (You’ll want to neutralize the remaining acid, for instance, filter out what remains of the gold flakes — and then there’s the part where you have to melt the gold, calling for some sort of kiln, crucible, tongs, etc.) If you want gold to a high degree of fineness (really close to 24K), you’ll probably need some special procedures.
