Embrittlement : Keep The Guns Out of The Oven

[Professor Marvel]

There are a number of netizens who wish to use their ovens to "antique" their firelocks, refinish their firelocks, or just want to "dry them out" after cleaning .

The danger in this method is the possibility that one may have a poorly calibrated dial, a misunderstanding of what temperature is safe, or a spousal unit who suddenly decides to turn the dial up to preheat the oven for a roast....

Thus, this missive is to warn our dear readers of the possible danger of accidentally exceeding 450 deg F

FYI 250 C == 482 F :

Temper Embrittlement
Abstract:

Temper embrittlement is inherent in many steels and can be characterized by reduced impact toughness. The state of temper embrittlement has practically no effect on other mechanical properties at room temperature. Many alloy steels have two temperature intervals of temper embrittlement. For instance, irreversible temper brittleness may appear within the interval of 250-400°C and reversible temper brittleness, within 450-650°C.

Temper embrittlement is inherent in many steels and can be characterized by reduced impact toughness. The state of temper embrittlement has practically no effect on other mechanical properties at room temperature.

Figure 1 shows schematically the effect of temperature on impact toughness of alloy steel which is strongly liable to temper embrittlement. Many alloy steels have two temperature intervals of temper embrittlement. For instance, irreversible temper brittleness may appear within the interval of 250-400°C and reversible temper brittleness, within 450-650°C.

If you feel (for whatever reason) you heat up gun or knife metal make certain you have an accurate thermometer and monitor your temperatures.

Does this apply to peanut butter brittlement?

Does this apply to peanut butter brittlement?

Fortunately, Peanut Brittle is by design already purposefully embritteled, so that it
will either correctly shatter in the users mouth, for most bestest enjoyability,  or alternatively,
it may incorrectly shatter the user's teeth.

As Always, YMMV

Prof Marvel Enterprises, Lmtd, makes no claims, guarantees, or warentees, express or implied

use peanut brittle at your own risk
peanut brittle has been known to cause tooth decay, broken teeth, broken fillings, broken dentures, broken implants,
broken marriages, broken promises, broken noses, long noses, nose warts, nose hairs, long hairs, falling hair,
shedding hair, hair brained, brain tumors, brain fever, brain fog, foggy bottoms, sagging drawers,
and other symptoms including death

peanut brittle is suspected to cause cancer in the state of California, but not if eaten in any other state.

Now I know what to blame it on, Thanks Professor!





Edit: Blaming peanut brittle related problems, not brittle gun problems. I never cook my guns past medium rare)

[Coffinmaker]

Monitoring of temperature with an after-market temperature gage is very important.  Once the guns are loaded on the baking rack  ,
continued monitoring and careful basting are necessary for particularly tasty pieces 

I do not cook anything past Medum Rare.  Even with careful basting and temperature control, a brace of Medium Rare pistols will still
be hard to cut and tough to chew.  I highly recommend a tenderizer 

Oh, and a Flame Knife

Ah My Good Coffinmaker

However could I have forgotten Basting! ?

I stand humbled before your superior revolver baking knowledge....
