if you are in the US - the oven broiler goes upto 500 - 550F (260-290C).
if you want to eat out of your dishes - if you use the lowest temperature clay - that is earthenware - you need to fire (1,800 and 2,100 °F) 1,000 and 1,150 °C and glaze-fired to between (1,740 to 1,920 °F) 950 to 1,050 °C.
if you make vessels to use as sculpture (so not to eat out of) you could either raku fire it (still need to bisque fire AND then glaze fire but still need heat at least to 1470-1830 F or pit fire in your backyard (still need to bisque fire) and then fire in a barrell or pit (if its legal where you are) to about temperature above 1000F.
that means you need a kiln. or have access to a kiln. if you have a ceramic supply store in your time you can enquire and find out if they fire individual pieces for customers or they know a place that does it.
that said i know some members here have built their own kilns from scratch. do you have space and time and means to do one?
you have to bisque fire first. well... and then instead of glazes you can use things like shoe polish or acrylic paint to paint on your pots.
but for eating use you need a kiln.
i have never heard of non heat based glazes. even in cooking you need heat to glaze the meat. but then just coz i dont know doesnt mean it does not exist.
