Title: Help needed - 9.75" Amber glass vase with everted rim and unusual finish
Post by: catshome on August 20, 2008, 03:12:27 PM

Hi,

This vase has a very "handmade" feel to it, but it's the finish I am curious about.  It's as though the hot form was sprayed with some sort of powder, or rolled in something, prior to the rim being folded over.  The rim does not meet the body.

The detail shot is of the bottom where there is more of whatever was used.  I did consider acid etching, but it seems more powdery.

The base has a polished rim, slightly concave middle.

Can anyone tell me what this technique is and, perhaps where it is used?  The closest I have seen is on Roman glass.

1. Marvering.

2. Most glass with applied colouring.

Just to expand on Frank's reply, the piece is marvered (rolled on a flat metal surface) in ground glass that (I'm assuming here) has a higher melting point; at any rate it fuses to the object without melting.  There are lots of ways of applying color at the furnace, and many involve marvering; all glassblowing involves marvering at some point.  I don't know if there's a more specific term for your decoration.  The same technique is used in "overshot" glass, but the glass bits are bigger and melt more.
