CFH microtorch

some pics of the CFH microtorch i use to solder silver with.

i read some comments on the net about the temperature of 3000 dgrees centigrade it allegedly could produce. i knew it is bullshit. it runs on lighter gas (propane/buthane mixture)and oxigen which it draws from the air, meaning that the flame temperature cannot reach 3000 degrees. it can still reach 1100, maybe even 1300 as stated on the package it was in. in the video i melt 3 different metals/alloys to show how hot it can get.

Is that a hunk of fire brick? Can this be an alternative to a crucible?

[fedaikn]

@heartmindspace nope, it's a regular brich. i carved ingot molds in it. used to pour lead ingots in that brick.

no, it is no alternative to a crucible.

So basically, you crave out a shape, then melt metal/silver until it fills the shape... Let it cool and your shape is ready for more processing?

Btw, is that a brick you use to make the shapes?

[fedaikn]

that is a regular brick. the molds in the brick were used to melt lead into ingots. it has nothing to do with silver except for the fact that it is resitant to heat. i used it in the past as a replacement for a charcoal block. now i use a refractory brick. i just improvise

if you melt silver do it on a flat and even surface, it will leave less indentations on the piece after cooling. keep in mind the high surface tension of molten silver as it will not fill small spaces

do u know the company site??

the problem with this test is the process is not adiabatic, the flames peak temperature will always be higer than your tests, espeshally as your using relatively large coins, still great video :D

[mikeyburger1]

the peak flame temperature for that will be around 1500 celsius if you could accurately check it (2732 Fht.)

(I was first about to say "cool" vid, but the wordplay was kind of poor...)

good video :)

im gonna buy one of these haha.
