Fused Glass Workshop RSVP Website: Blank Counts, a Kiln Cap, and a Firing Line
A fused glass workshop RSVP has to lock a glass blank and a kiln shelf before the first cut, because a maybe does not hold a glass blank.

A fused glass workshop breaks when six kiln shelves are planned and twelve people arrive expecting a glass blank, or when the glass order was built for six and two of those names were still a maybe on Friday. Glass blanks, the kiln shelf each piece fires on, and the firing you will actually run are set before the first cut. The host does not open a seventh blank because a neighbor decided to fuse after the sheet closed. This is cut glass stacked and melted flat in a kiln, not stained glass held with lead came and not a mosaic of tile set in grout. A maybe does not hold a glass blank.
You can create a fused glass workshop RSVP that fills the shelves you will actually load, records who is cutting and who is only watching the kiln, and stops when those seats are full.
Count the makers the kiln can hold
Walk the studio before you send the link. Write down how many shelves the kiln can load in one firing without pieces touching, how many glass blanks are already sorted by color, and whether a spare blank is a replacement for a cracked sheet or a seventh maker. If six shelves can each take one piece, that number is your cap: six makers, not a crowd sharing one sheet of glass and one cutter.
A fused glass station is one blank, one cutting mat, and one chair at the bench. You score, snap, stack the layers you named, and set the piece on a kiln shelf for a firing that runs after you leave. There is no lead came, no soldering iron, and no shared sheet that becomes someone else's tile. Ask whether a person who will not cut can watch from a chair away from the glass dust, and whether that person still counts toward the number the studio can hold. Pick one rule and write it on the page. Watchers stay off the bench. They do not score "one test strip" or start a second blank just to see the color.
Ask the last time you can change the glass order without paying for sheets you cannot return. If the supplier locks the blank order on Monday for a Saturday workshop, that Monday is your lock. Write the finish too: one blank, one named maker, benches swept only when the pieces you named are on the kiln shelf. A seventh blank "if a spare scrap turns up in the bin" is not a plan.
Set a capacity limit on cutting seats, not on everyone who was invited to watch the kiln load. When the sixth seat is taken, the form should say the workshop is full. If the blanks are already assigned, a late maker is not at these benches.
The firing line is a shelf count, not a vibe
Name the firing you will run and stop there. A clear line is one blank, one stacked piece, and a stop at "six pieces loaded and the kiln door closed," not a second firing for every guest's extra coaster. Fusing until the glass bin is empty is a different workshop, and you will not finish it in this block of time. Stained glass, with lead came and solder, is a different party. So is mosaic, with tile, nippers, and grout on a board.
Put that shelf count on the form as the point you will stop, not a vague "until the kiln looks full." If the workshop ends when six pieces are loaded and the schedule is set, that is the line. People who want to keep cutting until the color is gone will still be scoring when the kiln has to start. You need a yes to this blank, this shelf, and this firing line before you hand out glass.
Who can sit the bench, and who needs a different chair
Workshops go wrong when the seat is a surprise. Fused glass means sitting for a stretch, scoring with steady pressure, and working around sharp edges and a grinder that throws dust. Ask whether someone needs a taller chair, a standing-height table instead of a low bench, or a spot with room to stand back from the grinder. A guest who cannot sit through the cut does not get assigned a blank they will abandon halfway.
Collect seating preferences so you know who needs an end seat and who wants the blank on a higher table. Ask about accessibility needs before you assign blanks: a chair with or without arms, a larger-grip cutter, and a path that is not blocked by the kiln cart. Write what happens if someone misses the start: their blank goes to a standby already in the room, or it stays on the shelf and the late guest does not begin a second piece.
The moment the blanks are locked
The meeting point is the studio you named, not "the glass shop" with no bench marked. Put your phone on the page. A message in the group chat is not a blank assignment. You match names to kiln shelves.
Tie the deadline to the glass order, the day the maker count cannot change. After that, a late yes is a call about a cancellation, not a promise of another blank. If you want names ready when a maker drops, keep them as standbys and tell them they do not have glass until you write back. A maybe does not hold a glass blank.
Export the list the morning you lock: attending or not, which shelf, seating note, accessibility note, and phone. A fused glass RSVP is finished when every shelf has one named piece, the firing line is the load you will actually run, and a late guest knows whether they are cutting or watching from the chair.
