Just going back to the bentonite problem, I use plaster of paris for making rockets and salutes. I wet the powder slightly and mix(about 1:6 water to plaster of paris by volume). When this is rammed into a tube well by hand, it is strong and light. It isnt as good as bentonite, but it is cheaper and available from most chemists in the UK. the plugs can crumble if the tube is crushed. Adding more water and leaving to dry overnight would produce a much stronger plug, but i dont have the patience for this!

Finely powdered bentonite clay is available for a couple of quid per kilo, I would probably expect the chemist's prices to be a lot higher, PM me for source.

I used cat litter for a fountain the other day and i rammed it ok ( the rammer was slightly smaller ID than the tube ) but i found that the choke was blocked up after the fountain had ignited, by the looks of it, of melted cat litter. I may be wrong but just wondering if anybody had this before. Also i just looked on ebay and found many listings of bentonite clay powder being sold for less than 10 quid. Don't know if this is a rip off but it seems alright for bout 500g.

Divide that by five and then it would be reasonable.

So your saying this is 5 times better than a reasonable price?

He says it's 5 times worse, even £2 for 500g is steep, I get mine for £2 for about 15kg. I use alot of it though for furnaces.

Yes, annoying isn't it I made up three small fountains a while back using ground cat litter nozzles, hand drilled, and by the time I had transported them to the display only one would ignite. The other two had become completelely blocked by the crumbling clay.

Try the fine bentonite powder from Inoxia - it consolidates much better and doesn't crumble nearly as much in use. You can also wax treat your clay. Adding 5% paraffin wax (shaved candles will do) dissolved in Coleman Fuel (purified gasoline - beware the major fire hazard) and drying before use will make it more workable.

Yeah it was I might buy some of ebay as my dad won't let me buy anything else of the internet except on ebay I know that it might not be of the best quality but that's all i can do
