Ink Making Workshop RSVP Website: Pigment Counts, a Bench Cap, and a Bottle Line

An ink making workshop breaks when the host weighed pigment for eight vials, set six benches, and fifteen people answer yes after the jars are already portioned. Pigment, binder, mortars, and a clean slab are decided before the first grind. The host does not open a new jar or promise a bottle that has no pigment left because a friend decided to come after the list closed. This is grinding and bottling ink, not a calligraphy practice and not a print run. A maybe does not hold a vial.

You can create an ink making workshop RSVP that counts pigment shares, records access needs, and closes when the bench cap is reached.

Count pigment, vials, and slabs

Weigh the pigment before you send the invitation. Lampblack, a plant color, or another dry color becomes a bottle only after it is ground with a measured binder and capped. A small jar does not stretch because the room is enthusiastic. If one workshop yields eight labeled vials, eight portions is the material count. A student who wants “a little extra if the jar is still open” is asking you to spend someone else’s pigment.

Count the tools that touch the color. Mortars or glass slabs, mullers, spatulas, gloves, funnels, labels, and a vial with a cap for every maker are the limit. Two mortars do not create fifteen stations. People can watch a grind, but each person who leaves with ink still needs a portion cup and a bottle with their name on it. A slurry with nowhere to go becomes a stained cloth and a guest who thinks the workshop failed.

• Dry pigment weight, and how many vials that jar honestly fills

• Binder and water measured for that same count, not for a second round

• Slabs or mortars that fit on the benches without crowding elbows

• Gloves, labels, and caps so every bottle can be closed before anyone leaves

• A wipe-down plan, because pigment travels farther than the slab

An ink making place is one named maker with a pigment share, a grind station, and a vial. A guest who wants to see the first turns of the muller is not a student. Someone who expects to leave with a bottle needs a place in the portion tray. Ask who is grinding, who is only accompanying, and whether a late student will accept a smaller vial if a share opens. Students stay inside the pigment you already weighed. They do not scrape the jar because it still looks dark at the bottom.

The bench cap and the bottle line

Six benches and eight makers is a cap only if the session length, the slabs, and the vials agree. If you have six mortars and six portion cups, the cap is six, even if the jar could have stretched to eight. The smallest real constraint wins. Set a capacity limit for makers, not for every person who might stand near the color. When the last vial is claimed, the form should say the ink making workshop is full. If the pigment is portioned and the labels are written, a late guest is not an unplanned maker.

The bottle line is the end of the workshop. Name it: the last vial is capped, the label shows the pigment and the date, the slab is wiped, and the dry jar is closed. A clear bottle line stops the class from becoming an extra half hour of unlabeled slurry. Pigment left on a slab is not a promise to a guest who arrives during cleanup. It skins over, it stains the next cloth, and it is not a new seat.

Access and arrival fit a grind bench

Making ink means standing or sitting at a slab, gripping a muller, and working with a material that can smell, stain, or bother skin. That is a real barrier, not a detail for the day of class. Collect accessibility needs on the RSVP before you assign benches. Ask whether someone needs a seated station, a lower slab, a place to rest a cane off the work surface, or gloves because of a skin sensitivity you should know about before you set the portion cups. If you can set one bench at sitting height near a window or a vent, say how many of those benches exist. If you cannot, say that too, so a guest can decline instead of discovering the bench height at the door. Do not assign a vial that looks open on paper if that person cannot finish the grind before the bottle line.

Use arrival time windows on the RSVP because pigment is portioned for the people who are coming, not held open in the jar for an hour. The first window is names on labels, gloves on, and a short look at how the grind should look when it is ready. The start window is when the mullers move. A student who misses the start can keep their cup only if it is still in the tray. They do not get a fresh weigh-out. Put the host’s phone on the page so a delay is a message, not a guess.

The moment the vial list is locked

Tie the deadline to the weigh-out. If the pigment has to be portioned the night before a Saturday workshop, Friday is your lock. After that, a late yes is a call about a cancellation, not a promise of a mortar. Standbys can wait, and you tell them they do not have a vial until you write back. A maybe does not hold a measured cup of color.

The meeting point is the studio door, the check-in time, and the bench row you named, not “come by anytime and we will be making ink.” You match names to makers, vial size, bench, access notes, the bench cap, the bottle line, and a phone. Export the list the morning you lock: attending or not, pigment share, bench, access note, arrival window, and phone.

An ink making workshop RSVP is finished when every portion in the tray has a named vial, the bottle line is the last capped bottle rather than an open jar, and a late guest knows whether they are grinding, watching from a clean corner, or waiting for a cancellation.
