Frequently Asked Questions:
How do I place an order?
Step 1: Label your samples. Write the ID number directly on the sample or on the bag/vial containing them.
Step 2: Download and complete the order form from this website. The most current order form is always posted on the website.
Step 3: Email the order form with any questions or pertinent information to info@grindstonelab.com.
Step 4: If you are requesting a RUSH service, wait for confirmation from the lab (most likely Kendall).
Step 5: Pack the samples with bubble wrap or packing material to ensure they arrive safely. Ship the samples.
Step 6: Email the tracking information to info@grindstonelab.com.
We will confirm receipt of the order form as well as samples via email when they arrive. Once we log the samples and insert them into the production schedule, we will email you with any questions. The turnaround time starts from the day we receive the samples to the day we complete processing.
What types of material do you accept?
Rock, ore, mineral, soil, sediment, powders, meteorites, single grains, terracotta, ceramics, eggshells, bone, teeth, otoliths, fish scales, concrete, aggregates, roots, stems. If you are unsure whether your material can be made into a thin section, please call us for further recommendations.
How do I send sample material to the lab?
Box, bucket or bag. We accept sample material through the USPS, FedEx and other shipping providers. Be sure each sample has visible sample number and orientation (either marked or notched, if necessary) on the sample itself or sample bag/wrapping. Small Samples can be sent in vials or jars. Please be sure to include a copy of our order form with your order either with sample materials themselves or email to info@grindstonelab.com.
Do samples need to be pre-cut?
No, but there is a $10 cut fee for proper hand samples or highly specific cuts. Please identify area to be cut and sampled. Thumb-sized samples are ideal.
What do you do with the excess material?
By default any remaining sample material left after your thin sections have been made will be returned with the finished slides and billets – unless otherwise instructed by the client. We can also discard it at no cost, or we can archive your material for future use with a nominal fee.
Can I pre-embed my samples in epoxy?
We strongly recommend that you do not embed sample materials yourself unless there’s special circumstances. For those situations, we ask that you contact us to discuss options. Our lab cannot guarantee the performance or end result of an improperly mixed or cured epoxy. Please feel free to contact us and we can provide a procedure for you to embed your samples yourself to secure their transport to the lab.
My samples are very resinous/rich in hydrocarbons. Is this a problem?
Sometimes. We are more than happy to put your sample material through an extraction process to provide the best capture possible.
Can you make thin sections with a pre-existing billet made from another lab?
Yes. Final results will vary depending on the original quality of the billet.
Can I get permanent cover slips removed?
It would be an extreme situation where removing a cover slip is necessary in lieu of taking another thin section from the original billet. Chances are slim of preserving a thin section from cover slip removal.
How much is return shipping?
We primarily use FedEx 2-Day with return shipping. Depending on the size of your order, the rates generally range from $15 to $50. It typically takes 2 days for a business address and 3 days for residential. This is not included in turnaround time. If you need faster return shipping, let us know that you need FedEx Overnight. Please include this cost to your project estimate and/or purchase order.
What forms of payment to you accept?
We use Square merchant services for all invoicing. When you receive the email invoice, you have the option of paying with credit card or check. We prefer prepayment when using a credit card (if your agency allows). We also accommodate EFT/ACH, wired funds or cash (for local accounts). If you’re working with a Purchase Order or Service Contract, please include that number on your order form. We accept NET30 payment terms for Purchase Orders. Otherwise, payment is due upon receipt.
