About ResinBatch
ResinBatch is a small collection of practical planning tools for epoxy craft makers.
Built around the whole batch
A project can involve different molds, different piece counts and one shared mix. Our calculator combines that geometry into a clear volume plan, keeps the ratio basis visible, and provides a batch sheet you can keep beside your workspace.
Clear limits, useful numbers
We publish the formulas and assumptions, use manufacturer references for measurement guidance, and keep unsupported product recommendations out of the calculations. The tools are planning aids; your exact product instructions govern mixing and pouring.
Your projects stay on your device
Saving a project uses browser storage on the device you are using. It does not create an account or send the recipe to a server. Download a CSV or print a batch sheet if you want a separate copy. Read the privacy notes.
Feedback and corrections
A public support address has not been configured for this first version. Until it is, keep the input values and a description of the result to share with the site owner. We do not present the tools as manufacturer-certified or claim an expert review that has not happened.
