Well, thanks to the suggestion made recently on the list, I have found a source
for laterite that is pretty reasonable. What I propose to do is this: form
the laterite into coin-sized pieces and fire them. The biggest problem is
probably the kiln time, and as usual, the marketing. Here are the questions
1. What size coin? (I am currently thinking quarter).
2. What kind of packaging? (I am currently thinking one (a sample), ten or so
coins (for recharge or small tanks), and 100 or so for a big layer in a big
3. What about pricing? (I am currently thinking one is free, ten for $3.50
(incl. postage in the US), 100 for $24, postpaid).
Please let me know what you think. If this is too commercial, feel free to
reply off-list. Dave
