water based paint

[Sam]

Hi folks,

I have just started to take an interest in porcelain painting. I
bought a flower pot and some paint. The instructions on the paint,
which is water-based paint for porcelain, say that after the paint is
dry I should place it in the oven for 90mins at 160 degrees.

I was wondering why this needs to be done and what would happen later
on if I skipped the "baking" part. Thanks.

Regards,
Sam

This is not true porcelain paints that need to be fired on at temperatures
greater than a domestic oven.
I guess what you are talking about is similar to something I have seen which
needs to be fired to 90C. I am guessing that you are working in Farenheight
(sp) :o)
These "paints" are basically plastic. I think if you did not bake or fire
them on they would be very fragile and would clean off very easily.
They are fun, and create a bright finish. If you really want to get into
porcelain painting though I suggest that you join a group or class where you
have access to a kiln and get all the appropriate information.

thanks for your post annmarie.actually the temperature quoted is in
celcius but i couldnt find the celcius symbol on the keyboard.

what puzzled me with the paints instructions is that the paint stuck
to the pot quite well without firing.

maybe it depends on the material you are painting on. the pot has a
rough surface so maybe it sticks better.

rgds,

Hello Sam
In order to have all the beauty of the porcelain you must fire it very
high. In this case why not glazing or painting with ceramic mateials
like ceramic water colors or ceramic pastels? You can paint and smear
the pastels than cover with glaze.
I know that there is an acrylic for ceramics. In this case I believe
you paint and dry!

i think that the paints you used could be by Pebeo and are called
Pebeo Porcelain 160. they also do one called porcelain 150. the number
denotes the temperature at which they should be baked and are celsius
temps.they should be placed in a cold oven and brought up to temp and
then the oven is turned off but the item left in until the oven is
cold again.if you do not bake the item the paint will come off as the
heat is needed to fix it.i know someone who let her kids paint mugs
and cereal bowls as the colours are really bright but in time the
paint chipped and came off so i would not use these for utility ware
only for decorative ware.the only way to go is by using real porcelain
paints and kiln firing.
