When investigators discovered three deceased victims at a vehicle crash site over the side of Backbone Mountain they retraced the vehicle’s path and also discovered several pieces of broken glass lying in the roadway. In this lab, students will examine the refractive index of various glass fragments. They will learn the importance of glass analysis in the forensic field and how this analysis is performed by forensic scientists. In addition, students will learn to microscopically determine the refractive indices of several known types of glass, and then apply what they have learned in the comparison of glass fragments collected from a crime scene to a potential source.

  • Kit includes microscope slides, microscope cover slips, refractive index liquid 1: nD=1.45 (6 Bottles), refractive index liquid 2: nD=1.47 (6 bottles), refractive index liquid 3: nD=1.49 (6 bottles)
  • Also includes headlight reference glass (6 envelopes), bottle reference glass (6 envelopes), evidence questioned glass (6 envelopes), evidence known glass (6 envelopes)
  • Supplies are included for up to 30 students working in six groups
  • It can be stored at room temperature
  • This kit is geared to high school and undergraduate courses, and is matched to National Science Education Standards

Shipping Policy

WE SHIP WORLDWIDE: We primarily ship via FedEx, UPS, DHL, EMS, TNT, and USPS because they are fast, reliable, and easily trackable. We usually ship within two to three business days after the full payment. Standard delivery generally occurs within 5 to 7 business days after the shipping date. However, sometimes delivery may take about 7 to 10 business days, depending on the shipping destination, logistics mode, weather conditions, product weight, size, or shipping company distribution structures based on re-planning, such as staff shortages caused by COVID.

SHIPPING COSTS: For some industrial products, e.g., heavy wheels, CNC machines, etc., the shipping cost is calculated based on the product weight, not quantity. To benefit from lower shipping costs for orders with multiple items, don't hesitate to contact us at sales@ozrobotics.com. Our shipping rates are listed very clearly on each product page under the SHIPPING tab. Additionally, to see the shipping cost for your country, add the item to the Shopping Cart; you will see the shipping cost based on your Country and Location.

CUSTOMS and TARIFFS: While not all products require a tariff, some products may require a minimal tariff if applicable in your country for orders of $800.00 and above. The total amount for your order does not include a customs fee/tariff. A tariff belongs to the buyer when applicable. Why don't we add tariffs to the product's retail price? - If all countries deducted the same tariff amount, we would have added the tariff amount to the product price. However, we do not do that because each country charges a different amount, while some do not even charge. Therefore we can't add any tariff to the product's retail pricing. Oz Robotics, Manufacturing Partner, or Supplier are not responsible for tariffs. Please check the "Made In" and "Made By" labels on the product page to see the product's origin. The total amount for your order does not include any duties, import taxes, customs fees, and GST/VAT. The buyer must pay all import duties. Please click here to see more on Tariffs.

    Hi, I have some questions Does the RI of the liquids match the RI's of the glass samples? What type of scope do you need, compound? Do you need to be able to isolate a single wavelength with your scope or does bright light illumination work without any filter? My scopes do not have filters? How long does it take to get the shipoment? Thank you for your help Bill Hebard

    Hi William, we have just emailed you the PDF file. Thank you.

  2. Hello! My school has bought this kit several times in the past. However, we have found that the shelf life of the refractive index liquid is not as long as we wish it were. Unfortunately, many of our refractive index liquids have thickened and yellowed since they were purchased before the pandemic. Is there any way to purchase the liquids separately from the rest of the kit? We currently have all the other supplies necessary to complete the labs, but the RI liquids are occasionally yielding incorrect results.
