How to fix cracks in old metal Plant Pot?

[JD2012]

I found a old metal Plant Pot in the shed. I sanded it down as I was going to paint it and use for plants.

I have noticed though there are hairline cracks on three sides.

What would be the best thing to use to fill and bound these cracks?

I have attached pictures of the cracks.

Thanks

That looks like copper so it would be soldered originally.

Any reason it can't be used for plants even with the cracks?

Its a brass or a brass alloy not copper. I am not good at soldering though.

Its over 50 years old and i don't want the bottom giving way all together. I would just prefer it to fill them in and make it look nice before I paint it.

Tape over the crack on outside and squirt some CT1 along to seal , you can then remove tape after an hour or so and paint .
