Some stores with extensive stocks may carry various nitrates, although this may not be the case in Canada.

 

I was at a pottery store a few months ago and they had cryolite, copper oxide, sodium oxalate, and other things.

 

If shipping is cheap, buy some powdered bentonite. In my experience the stuff sourced from pottery stores is better than kitty litter.

im gonna be ordering from a american website because there is no pottery stores close to were i live so i may as well order from the states its better priced than the ones in canada

I do like powdered bentonite, but it's kind of a pain to work with. Messy, sticks to the inside of the tube and is difficult to measure precisely. Kitty litter, or granulated bentonite is so much easier to use. Plus it's basically everywhere.

The dextrin, copper carbonate and copper oxide would be useful too. Iron oxide should be something you have too.

Sculpy brand pottery clay if they have it. Stars to make with it;

 

 

Orange/Red star

Comments: Sculpy is a PVC based modelling clay - "FIMO" will also work, but is more difficult to mix.
Preparation:

Strontium nitrate.................................35
Potassium perchlorate.............................40
"Sculpy"..........................................22
Fe2O3.............................................2

Salmon color star

Comments: Sculpy is a PVC based modelling clay. The result is a salmon-berry (reddish-orange) color.
Preparation: Warm the sculpy slightly, to make it more mixable and mix it with the ammonium perchlorate without using solvents. Screen it several times and make pressed stars. The stars can be baked in an oven at 135 C for 20 minutes, which will result in much harder, more ignitable, more intensely colored stars. Heating the stars is not recommended though, since it could cause the stars to ignite.

Ammonium perchlorate..............................75
"Super Sculpy"....................................25

My local pottery store sells things for most sorts of modelling and sculpture so there are some metals for use as fillers in resin casting, Really it's up to you to see how much you can find in their catalogue that may be useful. Some of our esoteric catalysts are available as pottery glaze colours. What they will not sell you are the oxidisers that tend to be 50+% of everything.

Are you sure it's cheaper with the exchange rate sitting around 1.30?

Buying things locally usually attracts least attention and breaks fewer transport and customs rules, BUT sometime you will need to source the difficult oxidisers.

well i have all the oxidizer i could possibly want its just the carbonates i need now.

and i have yet to find a canadian pottery site that comes anywhere close to the prices of this website plus i only want to buy a pound of each lots of site have like 2.5kg min order and thats way to much but if you know of a good canadian website that compares with this place please link me cause i would much rather buy locally and save on shipping and less chance of customs stopping it :)
