/diy/ - Do It Yourself

that's pretty weird. Usually, microwaves lose power as they age. How old is it? you may need to get rid of it

Is the whole thing getting hotter? Maybe your cup is just getting hotter

>>1544658
If you use the same mugs, the waves might have hardened the finish on them and created more wave reflection in the mug against the water.

Some ceramics aren’t fired and contain trace amounts of water which might cause this under the right conditions

im pretty sure its your mug, not the microwave that's getting hotter.
it might be the ceramic is starting to lose its heat resistance as its aging.

altho i dont know shit about the mechanics of microwavelength limiters or internal build of those things but that just seems more plausible to me.

Microwaves can make tiny invisible cracks in the glaze which allows the ceramic to absorb moisture which is then heated by the microwaves. Older ceramics tend not to fair well in microwaves for some reason, might just be that once the glaze has some damage moisture gets in, microwave turns it to steam and the pressure builds cracking the glaze more.

Accidental discovery after doing some baked potatoes, the starch from the potatoes settled into those once invisible cracks and showing them off. Simple test, soak the cup for awhile, dry it off and stick it in the microwave for a minute, if it gets hot you know it is absorbing moisture.

Also your wall voltage could have increased, not sure how that would effect a microwave though.

use a kettle you spacker

>>1544658
Decreasing of the capacitor in the voltage multiplier arguably could have increased power output, voltage multipliers are funny like that.

Also this

its the mug deteriorating

>>1544664
This is halfway true. Microwaves work by exciting water molecules and causing the water in your tendies to heat up, therefore your tendies get warm.

The mug has be absorbing water over the years. Now you have water molecules trapped in the tiny pores in the ceramic so the mug gets warmer faster.

Also thIs was complete bullshit before I ever read this >>1544669

If it’s true, beppo is a certified genius idiot.

Thank y'all, very interesting. The mug is about 40-70 years old , and I got the burn on the opposite side of this little hole. It's always gotten hot there but suddenly it's cool off your burn under cold water for a minute, hot. Fortunately there is an unending supply of these mugs at the thrift store

This
>>1544787
Ya man chuck it before it heat stresses out to failure or burns you.

>>1544733
dubs of truth, what can I say

>>1544787
>those visible cracks
Holy shit you ruined that mug, put it on a shelf and use a kettle.
