wife and I went to 'big box' store today and purchased a nice light aluminum table for back porch use, but same table has what I'd call an 'openwork' surface, aka a decorative 'open' fretwork-like design lots of stuff in life can 'fall through', the tips of pens on paper JUST one example for 'starters'. we'd like to place a round glass .375 in thick tabletop on same table (also already purchased). problem is: the tabletop is intentionally made "crowned slightly"; tabletop's .250 in higher in the center than outer edges. so I'd like to find a source for .250 inch thick clear (or "near clear") silicone "buttons", or whatever these things are normally called. searches of google seemed no help...anybody know who makes these items in 'thicker thicknesses'? and what ARE these dang things 'called' anyway? alternately, I could cut them with a razor knife from 1/4 thick clear silicone sheeting, but can find no source for that, either...also would like some in .125 inch thick, or near, for mid-way between center and outer edge...
wide open here to alternate ideas - the table has some weird factory-applied finish which wouldn't lend itself well to having any other color 'buttons' between the glass and table 'frame'...
thanks in advance
