THE CLAY TABLE MEMBERSHIP GUIDELINES
Studio Location: 19 Brookline Street, Cambridge, MA 02139
Studio Website: www.theclaytablestudio.com
Studio Contact: hello@theclaytablestudio.com
1. Working in the Studio
These are some basic guidelines and principals for working within our studio and on our equipment. Please ask any of the studio managers for further clarification or advice. Should the studio be hosting a class, workshop, or private event, members will be notified well in advance.
1.1. Wheels
A wheel operation manual has been provided. Please be sure to read and refer to it as needed.
1.1.1. During use
Before turning on the wheel, always make sure the pedal is in the DOWN (heel-down) position.
When you are finished using the wheel, please leave the pedal in the down position as well.
NEVER turn off the power switch while the motor is running, as doing so may damage the internal belt of the wheel.
1.1.2. Cleaning
Before cleaning your wheel, please make sure the power switch is turned OFF.
DO NOT pour water directly onto the wheel to clean it.
Wipe the wheel down with a damp sponge or cloth. The splash pan can be removed, taken to the sink for cleaning and then placed back onto the wheel.
Cleaning your wheel includes the wheel head, bats, splash pans, the body of the wheel, and the surrounding area, including the floor, walls, and any nearby tables or shelving.
1.2. Slab Roller
Depending on what color clay you are working with (white/porcelain or dark clay), you will grab the corresponding canvas to lay down on the slab roller first. Slabs must be pre-flattened to approximately 1–1.5 inches thick before going through the machine. NEVER roll directly on the slab roller. Roll out on the work table.
Our slab roller has a dial that allows you to set a precise ruler measurement for slab thickness and should be checked and adjusted before each use. Sandwich your clay between the folded canvas and proceed to roll your slab. Clean up your mess, if any, and please remember that raw clay should never run through the rollers.
SAFETY when using the slab roller requires keeping hands, loose clothing, hair, and jewelry away from the rollers and all moving parts to avoid crushing injuries. Never place your hands under or near the rollers during operation. Use the safety pusher bar on motorized models when provided. Do not reverse the rollers if items become stuck; allow them to pass through completely.
1.3. Extruder: Training & Permission
Members may only use the extruder after receiving approved training from an authorized studio manager or instructor. If you have not been trained, do not operate the extruder under any circumstances.
If you would like to request training, please email us.
1.4. Kilns & Firing Procedure
1.4.1. Kiln authorization and access
ONLY trained studio managers are authorized to operate or access the kilns.
Members are strictly prohibited from touching, opening, adjusting, or operating the kilns at any time. This includes, but is not limited to, opening kiln lids, interacting with controllers, or accessing kilns, and especially while the kilns are firing or otherwise running, due to the risk of severe burns and injury. The Clay Table fires all our electric kilns at cone ^06-^04 for bisque and cone ^6 for glaze (that’s approximately 1880°F – 2200°F).
1.4.2. Emergency (Smoke, Fire, or Kiln Abnormality)
In the event of a kiln abnormality, or if you see smoke or fire, remain calm. Proceed immediately to the back room where the breakers are labeled “KILNS”, and switch the corresponding kiln breaker from “ON” to “OFF.” Immediately contact Hyo or a studio manager and continue calling until you are able to reach someone. Fire extinguishers and first aid supplies are located throughout the studio and should be used if needed.
Although we have ventilation in our kiln area, there are times you may smell some organic matter burning through the kiln and it can create a little smell. It is usually not a problem but if you are ever concerned, please call or text Hyo.
1.4.3. Firing turnaround
Our average firing turnaround time is approximately three weeks after pieces are placed on the firing circle shelves, though turnaround times may vary. Larger or oversized pieces may require additional time.
If any issues are identified prior to firing (such as bisque or glaze concerns), the piece will be moved to the Orphan or Oops shelves and accompanied by a note explaining the issue.
1.5. Tables
The worktables in the main room are divided by dark clay and white clay. If you are wedging or hand building, or doing similar work, please use the appropriate side of the table and be sure to always clean your workspace no matter how large or small the area used.
Please note that the wedging table is for wedging only and should not be used for drying work.
1.6. Spray Booth
The spray booth is available to members so long as they have their own face respirator. During the winter months, when you cannot go outside to sand your bisque ware, we allow you to use the spray booth for sanding. Likewise, if you have your own portable air compressor (from Home Depot) you can spray glaze onto your pots in our spray booth. If you use any communal tools, please clean up.
Procedure:
Close the door behind you.
Secure respirator on your face.
Turn on the power strip on the left-hand side of the spray booth, and work.
When you are done, take special care to clean thoroughly with a damp sponge and water, including the spray booth surfaces, floor, and surrounding area.
Turn off the switch and close the door.
1.7. Clay
We offer a variety of commercial clay bodies, and clay can be purchased directly through the studio website. Clay is sold in standard 25 lb bags only. At checkout, members need to enter their full name and pickup date. Please double-check the number on the box before purchasing clay on our website and picking it up. Members are also encouraged to label all clay bags with their name and clay type to help identify personal materials.
Members may purchase up to two bags of clay per month. Unused monthly clay allowances do not roll over. All clay used in the studio must be purchased through the studio website. Outside clay may not be brought into or used in the studio. Available clay types and pricing may change from time to time. Clay may not be sold or traded between members. Small, casual sharing between members is allowed, as long as it is not used to bypass monthly purchase limits.
Clay storage guidelines, including communal clay containers and personal cubby use, are outlined in the Section 2.1 (Personal Cubbies).
1.8. Glazing PLEASE READ CAREFULLY
1.8.1. Glaze Mixing & Raw Materials
Glaze raw materials and mixing ingredients are for authorized use only. Members are not permitted access or use glaze raw materials. Only trained and authorized studio managers are permitted to handle or mix these materials.
1.8.2. Glaze safety
Glaze before firing is considered a toxic substance and should be handled with care. Members with sensitive skin are encouraged to wear a pair of disposable gloves, which are provided by the studio at the glaze table.
All studio glazes are non-toxic and food-safe once fired and contain no lead. Glaze mixing is permitted only for those who have been trained by qualified The Clay Table studio managers.
1.8.3. Glaze handling
Using glaze, step by step
Open the glaze bucket and place the lid upside down on the table, with the messy side facing up. Use it as a small slop table to help contain drips.
Using the brush stored in the bucket, stir the glaze thoroughly before use.
Close the lid properly and securely before moving on to prevent the glaze from drying out or changing in consistency
Preventing Cross-Contamination When using Multiple Glazes
When working with multiple glazes, keep each brush on the lid of its corresponding glaze bucket to prevent cross-contamination.
Keep only one glaze bucket open at a time to avoid splashing or accidental spills.
Be mindful of brush placement and always return brushes to the correct bucket.
When layering glazes, allow the first glaze layer to fully dry before applying the next.
Please be aware of the space you’re using, as the studio can feel intimate during busy times.
Disposing of glaze
Glaze should not go down any sink. Glaze residue must be rinsed only in the glaze buckets provided and clearly labeled next to the glaze area.
You may use a little bit of clean water in a standard bucket to help you clean your work as you go. But please be mindful of how much water is already filled in the slop buckets and avoid overfilling them.
Please give all tools and cups a final rinse and place them back in the designated glaze area.
1.8.4. Glaze slip
The bottom of the piece must also include a clear mark (initials, stamp, or logo).
A glaze slip (see below) must also be completed and included.
Measurements are required only if any dimension exceeds 13 inches. In that case, all dimensions must be measured and recorded.
If glazes are layered, please list them as Glaze ① and Glaze ②.
1.8.5. Glaze running
Glaze running fee
If glaze runs onto a kiln shelf, a glaze running fee will be charged to cover cleanup and repairs. In this case, a note notifying you of the fee will be placed with your work. Please authorize the charge by filling out the note and placing it in the studio manager’s box.
Glaze running prevention
Glossier or shinier glazes have a higher likelihood of “running,” meaning the glaze continues to melt during firing and drips down your pot. Matte glazes have less likelihood of running but vary more significantly from one firing to the next.
Glaze is a mixture of glass, clay, and stabilizers so when in high temperatures it turns into high grade glue. Due to this if you get glaze near the bottom or on the bottom of your pot you would adhere your pot onto the glaze shelf and we would have to break your pot in order to get it off.
To avoid that we provide wax to make cleaning up easier, so when you are glazing, you should just wipe the bottom of your pot thoroughly. If we feel that a piece has been glazed in a risky or improper way, we will leave a note with the piece explaining our concern.
When glazing, please fill out a glaze slip so kiln loaders can better know whether your glaze choices are likely to be runny or problematic.
1.8.6. Glaze refire
Glaze refiring is available for eligible pieces and requires the glaze refiring fee. If you would like a piece to be refired, please clearly write “REFIRE” in the “MEMO” section of the glaze slip.
1.8.7. Test tiles
The studio provides a test tile wall to display glaze samples, showing how each glaze appears on both white and brown clay.
1.8.8. Commercial glazes
You may bring your own commercial glazes to use at The Clay Table as long as they are cone ^6. When using a commercial glaze, members must submit the commercial glaze approval form on the member portal. Once approved, you can use the glaze, and the name of the glaze must be clearly written on the glaze slip.
1.9. Oversized Work
Pieces with any dimension exceeding 13 inches may require additional kiln space, handling, or special placement and are subject to the oversized work fee.
The fee is calculated as Length × Width × Height, multiplied by the current oversized work rate (in dollars).
Examples (example rate shown below):
Size 14 x 10 x 4 x 0.05 (example rate) = 28 -> $28
If your work is oversized, please note the full dimensions on the oversized work fee note (see below) and place it in the box on the studio manager’s table. The oversized work fee will be charged to your payment method on file.
2. Work Storage & Shelving
The top of the shelving units is not intended for storage. Please do not place any work, tools, personal items, or materials on the top of the shelving units at any time. Any items found in this area may be discarded.
2.1. Personal Cubbies
Each member is assigned a personal cubby space for storing personal tools, small items, and their second bag of clay. If you need to move to a different cubby, please check in with the studio manager first.
At the bottom of each shelving unit, there is a designated communal clay container where members may store their first bag of clay. If you purchase a second bag of clay, it must be stored inside your personal cubby, not in the communal container. This system helps keep shared storage organized and ensures equal access to space for all members.
2.2. Works-in-Progress (WIP) Shelves (communal)
Designated communal shelves throughout the studio for storing in-progress pieces that are still being trimmed, assembled, dried, or otherwise not ready for the Firing Cycle Shelves. WIP shelves should be used only for active works that are still undergoing construction or drying. Unclaimed work will be discarded or donated after 2 months.
Personal wheel bats may be used for individual work. However, studio-provided wheel bats are shared tools and should not be placed on WIP shelves. Please keep studio bats separate from work-in-progress pieces and return them to their designated storage area after use.
2.3. Firing Cycle Shelves (communal)
In the kiln area you can find labeled shelving units that indicate where work at each stage of the firing process belongs:
Greenware: unfired work that is ready to be bisqued fired
(Please note: Due to limited space, only work at the leather-hard stage or beyond may be placed here. This area may not be used for drying purposes.)Bisqued work: work that has been bisqued
Glazed work: glazed pieces that are ready to be glaze fired
Glaze ware: fully glaze-fired finished work
In the firing cycle shelves, pieces are typically placed around eye level on the shelving unit first, and may move up or down the shelves the longer they remain there. Members are also encouraged to photograph and document the work they place into the kiln.
2.4. Communal Shelving Rules and Orphan Shelves
2.4.1. Proper identification
WIP
Write your label on masking tape using a Sharpie pen.
The label must include the NAME and DATE.
Greenware
Greenware must also include a clear MARK (initials, stamp, or logo).
Glazed work
The bottom of the piece must also include a clear MARK.
A GLAZE SLIP must also be completed and included.
For detailed requirements, please refer to Section 1.7.3 (Glaze slip).
2.4.2. Oops shelves
The following pieces will be moved to the Oops Shelf:
Greenware without a mark
Glazed work without mark and glaze slip
Pieces that are falling apart, broken, or structurally unstable and cannot be safely fired
Pieces with glaze runs
Unclaimed work on the Oops Shelf after 1 month may be discarded or donated.
2.4.3. Orphan shelves
Bisqued work and Glaze ware MUST be claimed within 1 month after it has been fired. Unclaimed work will be moved to the Orphan Shelf unless the studio is contacted by email or the member arranges for a studio mate or friend to assist with pickup. Work on the Orphan Shelf will be held for 1 additional month, after which it may be discarded or donated if still unclaimed.
2.5. Work Pickup, Storage, and Disposal Timeline
3. Studio Cleanliness & Care
3.1. General Clean-Up Responsibilities
Each station you worked at, area you touched, and tool you borrowed is your responsibility to clean up. When cleaning, please be mindful that the floor, walls, and tables are also your responsibility.
In order to prevent clay dust, which contains fine silica particles that can be HARMFUL if inhaled over time, ALWAYS use a damp sponge or water when cleaning dusty surfaces. Dry sweeping can cause silica dust to become airborne and pose a health risk. Please make sure to apply Clean Sweep to the floor before sweeping, for your safety and the safety of other members.
In order to keep our studio a safe and silica dust-free environment everyone is required to mop around their wheel after throwing.
Please help us keep the studio a safe working environment by keeping it clean and free of dust, germs, and trash. Cleaning supplies are provided for studio use, including brooms, dustpans, Clean Sweep, and mops, and are located in designated areas.
3.2. Clay Recycling
Members are highly encouraged to recycle their own clay whenever possible. Otherwise, all recyclable clay must be placed in the designated recycle bins to help reduce clogging in the slop sink. We provide separate bins for light clay and dark clay.
3.3. Sink Use & Drain Protection
Proper sink use is essential to maintaining a safe, functional, and clean studio environment. To protect our plumbing, equipment, and shared workspace, please follow the guidelines below at all times.
Please discard all clay chunks into the designated buckets first, and use the provided sieves or strainers to catch as much remaining clay as possible.
The studio does not have a designated food sink. Food-related dishes, containers, or utensils may not be washed or rinsed.
Be mindful of using minimal water when cleaning tools or work surfaces.
All glaze-related cleanup must be done using the designated glaze buckets and slop containers located in the glaze area, then final rinse here.
3.4. Damages & Maintenance Responsibility
Members will be held responsible for any damage to the facility or equipment if obvious negligence or improper use is the cause.
