Rich, I love your enthusiasm & always enjoy seeing your creations.
Contemps are not my thing but there is room for all.
Perhaps some vintage collectors were put off when you torched CAC cullet.
I do not believe your intent was to deceive anyone.
Any "seasoned" collector could tell the difference if needed.
You are not the first to experiment in this matter & probably won't be the last.
All artists have both fans & critics.
I say Post & Marble On!!
