With my glass painting I fill transparent, geometric spaces whose visual explorations produce surprising variations in forms. Different perspectives on apparent spherical floating built-up forms of linear brush strokes, reveal to the viewer new perspectives within the object‘s space.

I favour commercial float glass for my work.
In earlier pieces I cut these into slats, in themselves slight changing form which I layered in a stainless steel profile or between stone, wood or coal. It resulted in light converging fields or blocks of clear or coloured glass as an interruption in a tumben, glass contrary material.
Later I produced slim cases in which I stacked square, painted small glass slivers. Out of that the group of works, ‘Where the shark blows bubbles’ developed.
These days I work predominantly within this area. With delicate brush strokes I paint or draw on single panes that, layered and glued, seemingly float in the glass creating three dimensional shapes.
Those revealed paintings, similar to the above described box objects, at times more or less visible leading almost to a complete dissolution depending on the viewer’s angle, are mirrored on the inside of these object blocks which are polished on all sides.
In this way variations of forms are created, mirror axes, views of one and the same body depending on one’s point of observation.

Whenever you use this website, a variety of personal information will be collected. Personal data comprises data that can be used to personally identify you. This Data Protection Declaration explains which data we collect as well as the purposes we use this data for. It also explains how, and for which purpose the information is collected.
We herewith advise you that the transmission of data via the Internet (i.e. through e-mail communications) may be prone to security gaps. It is not possible to completely protect data against third party access.

Information about the responsible party
The data processing controller on this website is:
Wilfried Grootens . Am Deich 20F  . 47533 Kleve. Mobil: +49 171 7926108. wilfried.grootens@t‍-‍online.de

The controller is the natural person or legal entity that single-handedly or jointly with others makes decisions as to the purposes of and resources for the processing of personal data (e.g. names, e-mail addresses, etc.).

Revocation of your consent to the processing of data
A wide range of data processing transactions are possible only subject to your express consent. You can also revoke at any time any consent you have already given us. To do so, all you are required to do is sent us an informal notification via e-mail. This shall be without prejudice to the lawfulness of any data collection that occurred prior to your revocation.

Right to object to the collection of data in special cases; right to object to direct advertising (Art. 21 GDPR)
In the event that data are processed on the basis of Art. 6 Sect. 1 lit. e or f GDPR, you have the right to at any time object to the processing of your personal data based on grounds arising from your unique situation. This also applies to any profiling based on these provisions. To determine the legal basis, on which any processing of data is based, please consult this Data Protection Declaration. If you log an objection, we will no longer process your affected personal data, unless we are in a position to present compelling protection worthy grounds for the processing of your data, that outweigh your interests, rights and freedoms or if the purpose of the processing is the claiming, exercising or defence of legal entitlements (objection pursuant to Art. 21 Sect. 1 GDPR).
If your personal data is being processed in order to engage in direct advertising, you have the right to at any time object to the processing of your affected personal data for the purposes of such advertising. This also applies to profiling to the extent that it is affiliated with such direct advertising. If you object, your personal data will subsequently no longer be used for direct advertising purposes (objection pursuant to Art. 21 Sect. 2 GDPR).

Right to log a complaint with the competent supervisory agency
In the event of violations of the GDPR, data subjects are entitled to log a complaint with a supervisory agency, in particular in the member state where they usually maintain their domicile, place of work or at the place where the alleged violation occurred. The right to log a complaint is in effect regardless of any other administrative or court proceedings available as legal recourses.

Right to data portability
You have the right to demand that we hand over any data we automatically process on the basis of your consent or in order to fulfil a contract be handed over to you or a third party in a commonly used, machine readable format. If you should demand the direct transfer of the data to another controller, this will be done only if it is technically feasible.

SSL and/or TLS encryption
For security reasons and to protect the transmission of confidential content, such as purchase orders or inquiries you submit to us as the website operator, this website uses either an SSL or a TLS encryption programme. You can recognise an encrypted connection by checking whether the address line of the browser switches from “http://” to “https://” and also by the appearance of the lock icon in the browser line.
If the SSL or TLS encryption is activated, data you transmit to us cannot be read by third parties.

Information about, blockage, rectification and eradication of data
Within the scope of the applicable statutory provisions, you have the right to at any time demand information about your archived personal data, their source and recipients as well as the purpose of the processing of your data. You may also have a right to have your data rectified, blocked or eradicated. If you have questions about this subject matter or any other questions about personal data, please do not hesitate to contact us at any time at the address provided in section “Information Required by Law.”

Right to demand processing restrictions
You have the right to demand the imposition of restrictions as far as the processing of your personal data is concerned. To do so, you may contact us at any time at the address provided in section “Information Required by Law.” The right to demand restriction of processing applies in the following cases:
In the event that you should dispute the correctness of your data archived by us, we will usually need some time to verify this claim. During the time that this investigation is ongoing, you have the right to demand that we restrict the processing of your personal data.
If the processing of your personal data was/is conducted in an unlawful manner, you have the option to demand the restriction of the processing of your data in lieu of demanding the eradication of this data.
If we do not need your personal data any longer and you need it to exercise, defend or claim legal entitlements, you have the right to demand the restriction of the processing of your personal data instead of its eradication.
If you have raised an objection pursuant to Art. 21 Sect. 1 GDPR, your rights and our rights will have to be weighed against each other. As long as it has not been determined whose interests prevail, you have the right to demand a restriction of the processing of your personal data.
If you have restricted the processing of your personal data, these data – with the exception of their archiving – may be processed only subject to your consent or to claim, exercise or defend legal entitlements or to protect the rights of other natural persons or legal entities or for important public interest reasons cited by the European Union or a member state of the EU.

Rejection of unsolicited e-mails
We herewith object to the use of contact information published in conjunction with the mandatory information to be provided in section “Information Required by Law” to send us promotional and information material that we have not expressly requested. The operators of this website and its pages reserve the express right to take legal action in the event of the unsolicited sending of promotional information, for instance via SPAM messages.

The website operator has a legitimate interest in storing cookies to ensure the technically error free and optimised provision of the operator’s services. If other cookies (e.g. cookies for the analysis of your browsing patterns) should be stored, they are addressed separately in this Data Protection Declaration.

Server log files
The provider of this website and its pages automatically collects and stores information in so-called server log files, which your browser communicates to us automatically. The information comprises:

The IP address
This data is not merged with other data sources.
The operator of the website has a legitimate interest in the technically error free depiction and the optimization of the operator’s website. In order to achieve this, server log files must be recorded.

Request by e-mail, telephone or fax
If you contact us by e-mail, telephone or fax, your request, including all resulting personal data (name, request) will be stored and processed by us for the purpose of processing your request. We do not pass these data on without your consent.
The processing of these data is based on Art. 6 para. 1 lit. b GDPR, if your request is related to the execution of a contract or if it is necessary to carry out pre-contractual measures. In all other cases, the processing is based on your consent (Article 6 (1) a GDPR) and/or on our legitimate interests (Article 6 (1) (f) GDPR), since we have a legitimate interest in the effective processing of requests addressed to us.
The data sent by you to us via contact requests remain with us until you request us to delete, revoke your consent to the storage or the purpose for the data storage lapses (e.g. after completion of your request). Mandatory statutory provisions – in particular statutory retention periods – remain unaffected.
