Can i buy a roasting tin and s0mehow purposely make it rusty, and make a sign out of it?

Question

i have found rusty tin, but the ones i have found are not big enough for the project i want to do

i want to make a large picture to put on the wall about 12 inches square, or maybe bigger, or maybe rectangle

a baking sheet would probablt be about the right size

could i just but one and dip it in something for a few days to purpoely make it rusty, then i can paint my own design on to it

do you know how to do this i have asked in the science section because i am sure i remember doing somthing like this at school

what would be the best thing to paint with after, ot would it be better to draw with pens or somthing

thanks for your help

Answer 1

If I were you I would buy a baking sheet because they are flat. I'd go to a good cookery shop and be careful to buy a sheet which is the old fashioned kind, as in not a non-stick one.

This will be cheaper but will rust easily. I would then give it a good scrub at home with a scouring pad to slightly roughen the surface (which will aid rusting). I would then leave it outside somewhere safe for a few weeks as the outdoor atmosphere of changed temperatures, wind, sun, cool air, warm air and rain will dramatically speed up rusting. If you are trying to create an old advertising type sign/painting it might help if you do your painting before you do the rusting, the rust will be hard to paint over but if rust is wanted as part of your design then do the design first.

Answer 2

put it in water for a week when rusty use oil paints for your design

Answer 3

A cheap steel baking sheet should work. Make sure it's not aluminum or stainless - it should strongly attract a magnet. You'll need to sand the finish off, most likely. Give it an acid bath (dilute muriatic acid, or hot white vinegar), then soak it overnight in a hot saturated salt bath. Put it out in the sun. Mist it with a little salt water from time to time until it reaches the desired degree of rustiness, then wash it thoroughly  but gently to get the salt residue off.

A local scrap yard or sheet metal shop might be able to provide you with a suitable piece of sheet steel, possibly even pre-rusted.

Not sure what to paint it with. There are primers made to go on rusty steel, you might want to paint over a base layer of that.

Answer 4

I expect that roasting tins will all be made of a non-rusting metal or have some kind of coating to prevent rusting.  Your best bet is to buy a sheet of iron/steel of the size you want (try asking any local steelworks factories) and leaving it outside for a while.

Answer 5

If you go to a harware store and ask for some muriatic acid (or their might be other acids which would work as well) you can rust your baking tray in a couple of days.

For the painting, you can buy little tubs of paint specifically for use on metals, from any arts and crafts shop.

Answer 6

A new one will probably have something like varnish on to help prevent it rusting. You could scrub it with wire wool to scratch it, leave it in water, or outside somewhere very wet for a week and if neither of those work sprinkle some iron filing on it and leave it outside for a week for some rust stains to appear . (You could easily make your own iron filings with a large steel nail and a metal file.)

Some really cheap trays I've seen in shops obviously don't have any protective coating on, so I'd choose one of those to start with.

Answer 7

Buy a roasting tin, get it so hot it burns off the tin plate, leave it outside to rust, `wont take long if you keep it watered.

Answer 8

try sandpapering till you got the raw aluminium heat it up in the oven then cool with cold water quickly the expose it to the elements for a about two weeks
