well, anita and i scored some hno3 & had etch fever. we had a most embarrasing array of sky iron from social circle, ga, to taza, to gibeon and everything in between. results: gibeon: BEAUTIFUL, silver, aluminum-like etch- taza- SNOWFLAKE etch, sardis, ga KILLER big-crystal silver flashes! social circle- very weak etch- NO etch NEAR TROILITE crystals (troilite was EATEN AWAY and a void left in some areas, but the surrounding iron falied to take an etch). why did some work out and others not? after cautiously handling the smoking nitric, i found that etch was BETTER in more contrated solution- go strong, or go home. when i finally got it right for the gibeons that previously failed to etch AROUND TROILITE crystals, the solution turned dark brown and i had to fish around to find the skyrox (could not see 'em). bottom line: most
turned out EXCEPT social circle which refused to etch AROUND troilite crystals eventhough the troilite itself was eaten away a bit??? ANY INSITE / instruction on this edutaining experience would be helpful so that ETCHFEST '07 goes more efficiently.
i will be gradually switching over to yahoo mail (it has 100 FREE megs of storage). please cc to: [EMAIL PROTECTED]
