  1. Hi again, I was wondering over my above problem if there was any material that was both light (in terms of weight) and had a high heat capacity - if such a thing exists. I bought a whole lot of silicate pebbles which apparently is the best however my barbecue is now way to heavy for realistic use, any ideas?? Thanks Mik
  2. Thanks!! So from this I think that brick would be the way to go - apparently ceramic grog is basically fired ceramic which is then crushed might use this
  3. I am trying to keep the project as simple as possible and therefore wanted to use a simple material that I can cast or pour into the cavity. If the material were a solid this would also prevent me from having to have an airtight / watertight seal. Would brick, sand, stones or ceramin grog be the best then?
  4. Dear all, I am a design student, studying in South Africa and need help on a current project. I am designing a barbecue that doubles as a small fireplace. the idea is that once the fire is out the fireplace can be taken indoors to warm the house. So far my design can be simply put as 2 metal cylinders one inside the other - now I want to fill the gap with a material that has a high heat retention. the idea being that when the fire is burning (cooking food) the heat will be absorbed by this material, then once the fire is out the material will start to radiate the heat. I have had a few suggestions from my lecturers including, sand, brick, stone, salt (NaCl) and ceramic grog. I was wondering if there was any other material that could be better at this. I have also heard that water is the best at this but I don't think that it will work for my application as the area I will be putting the material is sealed and if water will boil and possibly explode. Any help will be appreciated!!! Thanks Mik
