came across the site and am hopeful you might be able to help me..I
own a pair of hand made Alain /mikli frames which I believe are
made from acetate. I took them into a steam room with me and across
the bridge they have whitened/misted on the surface.
Is it like a surface bloom? I’ve had that when solvent-polishing or
laminating acetate with acetone. According to Mazzucchelli, an
Italian manufacturer of acetate:
Optimum storage is about 20-25B0C and 45-55% relative humidity
[....] Excess water can cause blooming, which is difficult to
avoid even with high boiling point solvents [....] Polishing. a.
Superficial treatment with acetone by emersion or vaporisation.
Too long can cause flaking and cracking due to excessive
swelling. Use a dry environment. b. Dry rough tumbling. Use
adequate ventilation of the barrel and avoid over-loading. Too
high a temperature causes flaking, breakage or deformation. c.
Water rough tumbling. Not advisable for acetone treated
material. Tumbling method at 18-20B0C room temperature with
constant humidity: Stage 1. Roughing, 12hrs, birch rhomboid pegs,
spongy pumice, SL5 oil. Stage 2. Smoothing, 12hrs, birch rhomboid
pegs, hard pumice, SL5 oil. Stage 3. Polishing, 18hrs, rhomboid
pegs 1/3 cubes 1/3, cuspoids 1/3, polishing cream. Stage 4.
Finishing, 18hrs, rhomboid pegs 1/3 cubes 1/3, cuspoids 1/3, high
Do you know if I can polish this out/off and could you possibly
recommend a method and product that will do this?
I’ve usually buffed acetate using the usual silver abrasives. Try a
fine emery, gently rubbing. If that seems effective consider buffing
with white rouge on the flexishaft. I’d definitely NOT go near a
stationary buffing motor. The risk of them catching is too great.
