As a professional Brand of porcelain and ceramics for the entire range of restaurant and catering indutry we are optimally prepared for the different requirements of tableware. The total collection of Holst porcelain include more than 4.000 items and ideas in Design and Function - lives from the right combination "customer demand", "quality - price" and "design". That's why at Holst we carry six types of porcelain or ceramics.


The differences in the types of ceramic qualities are often perceptible to the layman. Only when viewed critically and are often difficult to understand. Many material properties stand in an irrevocable relation of raw materials and firing temperature, which create the essential characteristics of the respective ceramic assignment. The defined usage characteristics determine material and price at Holst and make the best possible use of the respective advantages of a material type. A high heat storage can not be achieved with a "thin" aluminum ash and a rich, colorful decoration not on a thick-walled feldspar body. We recommend, especially in the assessment of quality hardness of the material  to be considered that almost automatically from the firing temperature results.    

 

The Holst porcelain collection is composed of different ceramic material and qualities:

Our aim is to offer different target groups of professional hosts the best value for money, which also maxes out the advantages of the particular materials. A good thermal storage is not achievable with a "thin" Bone-China and a copious, high coloured dekoration does not work on a thick feldspar shard. For this reason we at Holst Porzellan run six different types of porcelain or ceramics, to serve the needs  and requirements of our clients individually and in the best possible way.

Thereby we have the ability - like car manufacturers - to serve our clients from entry level dish to premium class with brands in different market segments.

Qualities of types of ceramics

 

By definition of ceramics and composition of raw material of a body and its firing temperature result the "not visible qualities" of ceramic materials like the hardness of the glaze or its impact resistance. These factors are relevant for price, durability and longevity of wares but do not seem to be "significant criteria" for consumers. In the common decision tree with "quality" visible criteria is meant, which generally do not have an impact on the utility of dish. Quality reducing decision factores often are:

 

To offer a simple and understandable distinction of our qualities at Holst Porzellan we classify our "visible quality" into 3 levels.

 

1. High Quality
2. Basic
3. Budget
   
& II. Choice

 

High Quality by Holst Porzellan

 

The highest level of quality of Holst Porcelain is labeled as "High Quality"! The glaze is even, consistant and shiny. The ware does not have any visible faults or barriers. Tiny pinholes or minimal light refraction are only visible by strict and scrupulous inspection in individual cases. Deformations are not visible and bottoms are polished well. The ware is "top" but not perfect.

 

The amount of b-grade (minimal flaws) should not be higher than 5% (95/5).

 

Premium is dedicated to sophisticated hosts, four star hotel industry- and gastronomy, luxury hotels, starred chefs and all critical end-consumers. On this level we compare our ware to known brands like Rosenthal, Villeroy & Boch, RAK and more. As a good example for High Quality we have SkagenStyleHarmonyLubin and many more.  

 


 

Basic Quality by Holst Porzellan

 

These articles are our medium quality level of our collection. Glazes are even and shiny. Smaller, visual flaws on the surface neither impact the grace nor the intended use of the ware and are just visible by critical inspection or light refraction. The dimensional stability of functionable dish is warranted (exact dimension) and the common claim of the porcelain for daily use is given. This level of quality is a result of a "mix sorting" (a/b-grade).

 

The amount of b-grade (minimal flaws) should not be higher than 15% (85/15).

 

This sorting criteria conform the expectation of professional hosts, who know that a Schnitzel on an expensive manufactured plate does not taste better than on a cheaper option. On this level of quality we compare our ware to Tognana, Churchill, Kahle, Seltmann, Mitterteich, Vega, Lubiana and many more known brands in the game. As a good example for Basic Porcelain we have Basic, our BackwareLine Katja, the Pasta plates and many more.

 


 

Budget by Holst Porzellan

 

These articles offer the optimal bond between cost and performance. The glazes are even, small flaws on the surface do not affect the intended use of the ware. Smaller differences in the whiteness are visible by scrupulous inspection, but all in all not disturbing. Bottoms and bottomrings underneath can have pores or interruptions, which are not sharp. Big platters sometimes can wobble at a minimum on glass or other slick surfaces, which is no problem at all when using tablecloths. When stacked rims show an optical inequality, which only the dishwasher sees, but not the guest. This level of quality is a result of a tolerant "mix sorting" (a/b-grade).

 

The amount of b-grade (minimal flaws) should not be higher than 20% (80/20)

 

This sorting is dedicated to budget hotellery, cafés, bistros and cost-sensitive gastronomy. We underline, that we, Holst Porcelain do not "cheat" or describe Porcelain imitationsNew Bone China or others, inferior types of ceramics as Porcelain "by mistake". Budget is at Holst Porzellan a real quality of Feldspar Porcelain, which meets all requirements of professional use. Fired at more than 1.320 °C our low-cost dish is not cheap, but good! On this level of quality we compare our ware to Royale, Saronno, Saturnia, Ikea, Maxwell & Williams, Pordamsa, Crea-Table and not with WAS, Pulsiva, Welco, Luzerne, Ionia, Tuxton as well as all kinds of Ceramics.
