Denser materials like oak flooring will generally show sharper lines of demarcation than polymer e. The absence of a carpet pad often leads to sharper lines. Irregular patterns are common in situations of post flashover conditions, long extinguishing times, or building collapse. These patterns may result from the effects of hot gases, flaming and smoldering debris, melted plastics, or ignitable liquids. The presence of ignitable liquids is suspected, supporting evidence in the form of a laboratory analysis should be sought. It should be noted that many plastic materials release hydrocarbon fumes when they pyrolyze or burn. These fumes may have an odor similar to that of petroleum products and can be detected by combustible gas indicators when no ignitable liquid accelerant has been used. It should be noted that pyrolysis products, including hydrocarbons, can be detected in laboratory analysis of fire debris in the absence of the use of accelerants. It can be helpful for the laboratory, when analyzing carpet debris, to burn a portion of the comparison sample and run a gas chromatographic-mass spectrometric analysis on both samples.

Antique Ink Bottles An ink bottle was made of glass and typically sat on a desk. The writer would dip the pen or quill into the bottle to put more ink on the pen. Because they set on a desk, ink bottles were often decorative. Ink wells as opposed to “ink bottles” were typically metal with a glass insert, often ornate, and sat on a desk. The larger master ink pint or quart size was used to store ink and refill the smaller ink wells.

News: Ink of the Year 2018 – Olivine
Under an Elsevier user license open access Abstract Attenuated total reflectance ATR Fourier transform infrared FTIR spectroscopy associated to linear discriminant analysis LDA was employed to perform classification of blue pen ink according to types and brands, in a nondestructive way. To build a representative data set, blue pens of 3 types, namely ballpoint 5 brands , roller ball 2 brands and gel 3 brands were purchased from local dealers.
Ten different pens, representing the best seller of each brand, were purchased, making a total of pens. Three types of paper were employed:

To decode Martha Ballard’s diary, you will need to understand how she structured her pages, how she recorded the date, and how she used abbreviations and marginalia. Rollover the headings below to see fragments decoded. Read more about these and other aspects of Martha’s diary her ink, her pen, the layout of the diary, etc. She recorded not only the day of the month, but also the day of the week. Sunday, the first day in the week, is identified with one of the letters from A to G, corresponding to the”dominical letters” used in almanacs “dies dominica” is Latin for Sunday.
Monday is always 2, Tuesday 3, Wednesday 4, etc. Martha infrequently used 1, instead of a letter, for a Sunday. Midwifery accounting in her margins — Martha clearly paid special attention to her midwifery practice. Although she noted numerous other kinds of financial transactions in the body of her diary entries, she kept margin notes only of her midwifery accounts.
Most probably this allowed her to find her midwifery accounts quickly when scanning through her diary. Over the years, she labeled and carefully numbered more than deliveries in the left-hand margin of her diary.

The questioned document was a list of 29 pages containing a consecutive handwritten numbering and dated entries payments made of blue ballpoint pen ink. By definition, a cash book has to be written by hand and the entries have to be made daily. The questioned document was suspected to have been written within a short period e. The document lab was asked to determine the date of the entries of the questioned list.
On one hand, we were asked, if the cash book had been kept on account consecutively during the period of one year, and on the other hand, the judges were interested in knowing, if the document could have been written in and back dated to To answer these questions, the document was examined for latent elements by electrostatic detection device ESDA. The relative dating of the entries was performed by the quantification of the ballpoint pen ink dyes and their degradation products using HPLC.
Results show that it is possible to determine the relative age of entries written by ballpoint pen within a relatively short time scale, if storage and supporting material of the different samples are the same or at least similar.

Open Access funded by Engineering and Physical Sciences Research Council Under a Creative Commons license open access Abstract Although degradation of iron gall ink containing paper has been scientifically studied for almost years, we still do not have a good understanding of the kinetics of the process. While many studies focussed on model samples to avoid the inhomogeneity of real historic samples or the need for sampling, this research was conducted on a selection of real documents.
The analytical methods were optimised such that sample consumption was minimised and errors and uncertainties were evaluated. The results show that the rate of degradation, measured as change in the degree of polymerisation of cellulose in paper beneath ink, can be described in Arrhenius terms, and that the apparent activation energy for the process depends on the moisture content in the material.

Several of these were adopted after by Doulton and remained in use for about twenty years. The following are two typical examples found on the patterns Rouen and Kew. Various other pattern names will be found. The coronet on B. The mark continued in use until This mark continued in use until

In this paper we describe a case in which a cash book, dated of the year , was sent to the Forensic Science Division, Document Laboratory, Zurich Canton Police in March The questioned document was a list of 29 pages containing a consecutive handwritten numbering and dated entries payments made of blue ballpoint pen ink. The questioned document was suspected to have been written within a short period e. The document lab was asked to determine the date of the entries of the questioned list.
On one hand, we were asked, if the cash book had been kept on account consecutively during the period of one year, and on the other hand, the judges were interested in knowing, if the document could have been written in and back dated to To answer these questions, the document was examined for latent elements by electrostatic detection device ESDA.
Results show that it is possible to determine the relative age of entries written by ballpoint pen within a relatively short time scale, if storage and supporting material of the different samples are the same or at least similar. But one of the most challenging investigations is the dating of entries. If a questioned document is written by means of mechanical devices typewriter, inkjet printer, laser printer, copy machines, etc. In case of handwritten entries, this method is only valid for very old documents.
However, a maximum age determination is in general not adequate to answer the question concerning a forgery by backdating. Because the signature, produced with ballpoint pen, is often the only handwritten trace in a questioned document, it represents the most important element for document dating analysis.
