        Just a few tips from a photographer who's used these things.
1. The older models (pre 1976?) heated hotter than the later ones,
without as reliable a thermostat, which is fine for anything other than
resin coated photos, which virtually all photos are anymore. Those they
melt, badly. The newer ones, with the lower temp's, require the use of
"R.C." mounting tissue to bond, the older ones will bond either type of
dry mount tissue.

2. The Dry Mount glue is NOT what one would consider archival quality!

3. Whichever type you purchase, it is well worth the expense of buying
"heat test strips" which turn color at a pre-defined temperature to
verify you thermostat's actual setting. Never Trust The ThermostaT Dial!

4. The correct order for mounting, from the bottom up, ia a thin piece
of board, smooth, the board you want to mount on, the artwork, the matte
frame, if you have one, a board the same size & thickness as the matte
cutout, for the center, a fairly stiff cover board, and finally another
thin board over it all.

Hope this ism helpful.
