Thought you would like to see the result of the Pyrocrete material rather than the Fondue that is no longer available.
After many trials of ratio's and tests I arrived at the following. 1 part Pyrocrete. 3 parts sand.1 teaspoon of colored oxide. A 50/50 mix of water and Bondcrete or exterier pva glue.
Mix in small amounts at a time.( no more than 1 mug of Pyrocrete) and add fluid mix untill consistancy of ceiling paint for brushing on.
I found the best method was to use this amount mix up on the prepared pot.( chicken wire and dynacloth) untill it set up then repeat.
You can leave it a natural color but I gave it a light spray of hammer head bronze spray paint with black oxide.
I still maintain though that the Cement Fondue is better.

Is it likely to release chemicals into the soil? Some of those mixtures really stink for a long time until they age.

hi guys,

the technique is pretty much the same for pyrocrete or fondue, same theory anyways, you can see alan's thread here - viewtopic.php?f=45&t=1156&p=47576&hilit ... due#p47576

chemicals shouldnt leach into the soil if you allow the pot to dry completely and im not talking touch dry, im talking set rock hard, should be around 2-4 weeks depending on how thick the crete is ;)

Jamie :D

Thanks for that Jamie.
Yes it turned rock hard after a week, I had to give it many coats and give it time to set each coat.
Pyrocrete is a flame retardant that is sprayed onto walls or mixed in concrete.
Dynacloth and fibre glass close weave cloth can be found in the well known boating merchant supplies. Both are used on boat repairs.
