Resin Casting Pot Life and Exothermic Temperature Tracker
Overview
A clean, professional-grade, browser-based utility designed for resin artists and casting professionals. This tool provides a reliable countdown for resin pot life (working time) and a secondary monitoring phase for the exothermic curing cycle. It features a high-visibility, light-themed interface built for safety and precision.
Technical Constraints & Directives
- Single File: All HTML, CSS, and Vanilla JS must reside in one file. Use CDNs for Tailwind CSS and Lucide icons.
- No Storage: ABSOLUTELY NO usage of
localStorage,sessionStorage,IndexedDB, or cookies. The state must be entirely in-memory. - No Popups: Use custom HTML/CSS modals for all alerts, inputs, and confirmations.
- Sandboxed Iframe: The code must be compatible with a null-origin iframe (no blocked access to system-level storage).
- No Branding: Ensure all copy is generic and functional.
UI/UX Design
- Aesthetic: Modern, vibrant, professional SaaS look. High contrast, sans-serif typography (e.g., Inter or Geist). Strict light-mode color palette: whites, soft grays, and energetic primary colors (electric blue for active, amber for warning, crimson for safety critical).
- Layout:
- Header: A simple, descriptive title and a 'Reset' button.
- Main Input Section: Simple numeric inputs for 'Pot Life (minutes)' and 'Initial Mix Time'.
- Central Display: A large, prominent circular countdown timer that changes color based on remaining time (Green -> Yellow -> Orange).
- Safety Module: A dynamic text area below the timer displaying specific phase warnings (e.g., "Safe to Pour," "Gelation Starting," "Peak Exotherm Expected").
- Safety Checklist: An interactive (non-persistent) checkbox list for safety steps (Gloves, Respirator, Ventilation, Stable Surface).
Feature Set
- Dynamic Countdown Timer: Allows users to set custom duration for their specific resin type. The timer uses CSS transitions for smooth ticking.
- Exothermic Phase Timeline: Once the pot life timer hits zero, a secondary "Observation" timer triggers, providing visual cues for when the resin should be entering its peak exothermic phase.
- Visual Cues: The background of the timer container will slowly shift hues to reflect the urgency of the phase.
- Safety Reminders: A persistent, non-intrusive modal or static list of best practices for casting (e.g., 'Ensure adequate ventilation').
- Responsive Design: The UI will stack vertically on mobile (Timer on top, safety list below) and expand horizontally on desktop to show both side-by-side.
Animations
- Micro-interactions: Use CSS transitions for button hover states (slightly scale up, shadow increase).
- Timer Transitions: Fade-in/out effects when moving from 'Pot Life' to 'Exothermic Observation'.
- Pulse Effect: A subtle pulse animation on the container when the pot life timer is in its final minute to draw attention.

Frequently Asked Questions
Everything you need to know about using this application.
How do I accurately use the resin casting pot life and temperature timer?
To use this tool, first identify the pot life duration listed on your specific resin manufacturer's technical data sheet. Input this time into the duration field before you begin mixing your components. Once you start the timer, the application will provide a visual countdown to help you understand exactly when your working time is ending and the gelation phase begins. After the pot life expires, the tool transitions into an observation mode. While this tool does not measure physical temperature, it serves as a reliable reminder to periodically check for signs of an exothermic reaction, such as increased heat or thinning/thickening viscosity. Monitoring these phases allows you to safely manage your casting project.
What is an exothermic reaction and why should I track it?
An exothermic reaction in resin casting occurs when the chemical reaction between the resin and hardener generates heat. As the polymer chains cross-link, the mixture releases thermal energy, which can cause the cup or mold to become warm or hot to the touch. This process is essential for curing but can be dangerous if the reaction proceeds too quickly or in too large a mass. Tracking the progress of this reaction is critical for safety and project success. If a resin batch generates too much heat, it can release toxic fumes, warp plastic molds, or even cause the resin to smoke or crack. By monitoring the timeline of your pour, you can ensure that you are aware of when the material is at its peak exothermic phase, allowing you to take appropriate safety precautions.
Is my data saved by this resin casting timer tool?
This application operates strictly within your browser's volatile memory and does not use local storage, cookies, or any persistent databases. Every time you refresh the page or close your browser, the timer and any input parameters are completely cleared. This design ensures your privacy and adheres to strict security protocols for web-based tools. Because the tool does not save data, it is designed for real-time, one-off project sessions. If you need to keep track of multiple pours or resin types, you should manually record your timing data in a separate log. This approach eliminates the need for complex data management or user accounts, making the tool faster and more accessible for immediate use.
Does this tool work on mobile devices for workshop use?
Yes, the application is built with a mobile-first, responsive design approach to ensure it works seamlessly on smartphones and tablets. Whether you are in a dedicated workshop or a hobbyist studio, you can keep your mobile device nearby to monitor your resin pot life timer without needing a desktop computer. The interface uses large, high-contrast buttons and clear typography to remain readable in various lighting conditions. To ensure the best experience, we recommend keeping your device screen awake while the timer is running. The clean, light-mode interface minimizes power consumption and prevents eye strain during long curing periods. All features, including safety reminders and phase tracking, are fully accessible on touch-screen interfaces, providing a professional experience regardless of your chosen hardware.
